AI Marketplace Tracker·v6.3: user-scoped MCP is the settled default

Who’s Shipping On AI Marketplaces?


A live record of HR, payroll, and accounting vendors with verified AI marketplace presence, Claude Plugin Directory, Anthropic Connectors Directory, OpenAI Business Apps, and vendor-published MCP servers. This is the canonical view of who has made the plugin distribution bet.

Last audited: 21 September 2026 (V6.3: Workable widens its MCP to the full HR lifecycle on the user-scoped model, the third user-scoped-write agent connector in four days. Workable expanded its MCP server from 57 to 94 tools (July 20), adding the full 15-tool performance-review lifecycle and candidate-profile writes across Claude and ChatGPT, with every session "scoped to the authenticated user's existing role and access." With Omni HR and BambooHR earlier in the week, user-scoped write is now the settled mid-market default, being stress-tested on the sensitive performance-review surface. The buyer-side mirror: sophisticated customers place one governed gateway in front of all agent access, so a vendor connector that dumps broad access on a shared token fails there while a cleanly user-scoped one passes through. Note: this day's headline (Intuit's QuickBooks business card and OneSource Virtual's federally chartered trust bank) is a money-rail story, not a marketplace one. Prior, V6.2: the mid-market HCM tier ships agentic platforms as a bloc, and every one leads with the boundary. In ~48 hours, Paylocity Ignite AI (GA, control plane, internal), BambooHR Bamboo AI (private beta, MCP to ChatGPT/Claude, permission-scoped/attestable) and Netchex Mesh (early access, six deskless agents accessible in ChatGPT/Claude, human-approval-gated) all launched named-agent platforms. Agentic HCM is now table stakes at the mid-market; the governance surface is the differentiator, and every payroll agent stays one step back from running the payroll. Same-day counter-signal: Morgan Stanley downgraded Workday to Underweight over gradual AI monetization. Netchex added to Live. Prior, V6.1: the write-scope governance middle path ships, from an emerging vendor. Omni HR, an APAC unified HR and payroll platform, launched a vendor-published read-write MCP connector, July 20, exposing employee data, lifecycle and time off to Claude, ChatGPT and Cursor, with every agent action scoped to the operating user's own permissions and nothing retained at the connector. It is the middle path between HiBob's write-by-default connector on a shared service-account token and the read-only tax engine that refuses to act: write capability with per-person attestation, shipped by an emerging vendor before the largest platforms. Channel 3 custom MCP, early access. Prior, V6.0: the first infrastructure-supplier MCP, and it bets read-only. Symmetry, the payroll-tax engine embedded inside Gusto, UKG and Paychex, launched an MCP server exposing tax determination and multi-state pay calculation to AI agents through a read-only interface that cannot mutate payroll runs, client data or tax rules, July 15. First customer UZIO; Channel 3 custom MCP; US and Canada only. It is the counter-pattern to the write-scope wave and the first clean answer to the accuracy problem under agentic payroll. Otherwise quiet: no other net-new HR and payroll marketplace entry in the July 10–17 window; the Anthropic Connectors Directory unchanged since isolved on June 16. Prior, V5.9: two ledger corrections. HiBob's MCP server verified live in shipped beta with read-write scope on employee records and time off, service-user auth only, live since at least Q2; and the Deel App for ChatGPT, live since April 24 with transactional scope for authenticated clients, caught as a missed launch. No net-new marketplace entry in the July 3–10 window; the Anthropic Connectors Directory held at roughly 554 connectors with no HR and payroll addition since isolved on June 16. V5.8 carried: Check Payroll MCP re-dated to its March 26 announcement and logged as payroll-infrastructure rather than a retail competitor. Prior: V5.7, 17 June 2026: a mid-market HCM incumbent enters the directory. isolved launches GA of its Connector for Claude in the Anthropic Connectors Directory and ships six named autonomous HR, payroll and benefits agents under a new "Workforce Capital Management" category at SHRM26, June 16, the first SMB and mid-market incumbent of its scale to take the Anthropic-direct path. Abacor, an accountant and advisor meeting-context platform, ships an MCP connector, June 4. V5.6 carried: Workable's 38-tool MCP, May 13; Remote's MCP, June 4; Omni HR Mino, June 8; ZipRecruiter via Claude, June 9; Lattice MCP, June 10; Workday Agent-Ready Tools, June 2.)

Understanding The Claude Marketplace

“Is Vendor X on Claude?” is not a simple yes/no question. Anthropic operates three distinct distribution channels, and vendors can be in one, two, all, or none of them. This page uses precise categories so readers can see exactly how a vendor is present.

The Three Channels

Anthropic has three distinct ways a vendor can “ship on Claude”

  1. Claude Plugin Directory Bundled plugin packages listed at claude.com/plugins. Work with Claude Code and Claude Cowork. Anthropic-curated via a managed GitHub repository. Plugins combine MCP servers, skills, commands, and sub-agents into one installable unit. Highest trust signal, highest vendor effort. No third-party HR/payroll vendor is currently in this directory.
  2. Anthropic Connectors Directory Curated MCP servers at claude.ai/directory. Launched July 2025. Works across all Claude products, Web, Desktop, mobile, Code, API. Anthropic reviews submissions for security and compatibility. Launch partners: Notion, Stripe, Asana, Atlassian, Intercom, Canva, Figma. As of April 2026, Gusto and Intuit QuickBooks are both live in the Connectors Directory, the first HR&P-adjacent vendors admitted.
  3. Custom Remote MCP Connectors Any vendor can publish an MCP server at a public URL; customers install it manually as a custom connector. Not curated by Anthropic. Gusto initially launched via this channel (Apr 8, 2026) but has since been promoted to the Connectors Directory.

A fourth strategic option is a named multi-year Anthropic partnership, which goes beyond directory listings to bi-directional integration (Claude inside the vendor’s product AND vendor data inside Claude) with joint engineering and co-marketing. Xero and Intuit have taken this route for SMB accounting/payroll. No pure HR vendor has a comparable partnership.

For MCP servers outside Anthropic’s curation, trust tiers matter: Official (vendor-published, vendor-maintained), Community (third-party, meets minimum quality threshold), or Managed 3P (commercial integration vendor like CData or StackOne wrapping the source API).

Anthropic’s Native Cowork Plugin Library

For reference: the free generic capability layer that every Claude Cowork customer gets without a vendor partnership. The Human Resources plugin is the most directly relevant, it handles generic HR tasks without any third-party integration.

Official GANov 2025

Dynamics 365 ERP MCP Server reached general availability in the 10.0.47 release. Exposes 650,000+ operations across Finance, Supply Chain, Human Resources, and Project Operations.

What’s exposed

Create, read, update, and delete operations across data entities in Finance, Supply Chain, HR, and Project Operations. Form Interaction, API Action, and Data tools. The first hyperscaler-scale enterprise platform accessibility commitment and the reference bar for every other vendor’s plugin strategy.

05

Transition Watch

Vendors with documented in-product AI capabilities but no published MCP server, no Anthropic partnership, and no entry in any curated directory. These are the vendors most likely to transition to marketplace distribution next. Each row represents a market position worth watching weekly, if any of them ship a plugin or MCP, they move to the Live section above.

Vendor In-Product AI Capability Community / 3P MCP Notes
Rippling Live data Q&A, Rippling AI across HCM modules Multiple community servers exist (rocketsciencegg/rippling-mcp-server 2 stars; bifrost-mcp/rippling-mcp 0 stars, 18 tools across 6 domains), both below quality threshold Highest market visibility. AI strategy is internal-first. The April NYC roadshow may signal marketplace ambition.
Workday Sana (GA worldwide, 300+ skills), Illuminate agents, Workday GO Agent-Ready Tools, announced June 2 2026: MCP-based connectors that expose Workday HR and finance data to external agents under Workday’s own security model. Early access via Extend Professional, GA targeted for H2 2026, fed by Pipedream. Announced alongside an Agent Passport attestation scheme, with Cisco as the first named partner. The reversal has happened. Workday, previously the clearest case of the closed camp, is opening MCP access to external agents as of June 2 2026. The shift was visible in April, when a reference MCP architecture appeared the same week the CTO departed for Anthropic; the June announcement makes it strategy. Now trending hybrid/open. Moves to the Live section above when general availability ships in H2 2026.
ADP Lyric HCM AI features, multiple in-product agents No vendor MCP verified on Claude or OpenAI channels; CData commercial wrapper only (Managed 3P). ADP Marketplace AI Agents launched March 2 2026: curated partner-built agents from Absorb, Aquera, G-P, Built, Employ, Praisidio, Salary.com, Tapcheck, MakeShift, Payactiv, and Quantum Workplace, distributed inside ADP’s own marketplace. Largest payroll incumbent. No longer zero external distribution: since March 2 2026 ADP distributes partner-built agents, but through its own marketplace rather than the AI platforms. The first-mover window on Claude and ChatGPT channels remains open.
Dayforce Dayforce AI Workspace, compliance monitoring, performance coaching, payroll anomaly detection Via Microsoft Copilot Studio partnership, not a standalone Dayforce MCP Hybrid case. Dayforce chose to distribute via Microsoft’s MCP ecosystem rather than publish its own. Worth watching whether this becomes a third path (ride a hyperscaler).
Paylocity In-product AI assistant, AI-driven insights CData commercial wrapper only (Managed 3P, read-only via JDBC) Mid-market HCM. No vendor-published MCP.
UKG AI features across UKG Ready and UKG Pro None verified Recent “workforce operating platform” rebrand could include marketplace distribution as a future roadmap item.
Deel In-product AI for global payroll; Akai AI ops platform Deel App for ChatGPT live since Apr 24 2026 (MCP-based; clients start contracts, approve requests and track onboarding in-chat). No Anthropic-channel presence. $17.3B valuation, IPO prep. The marketplace-distribution trigger fired in April on the OpenAI channel; the open question is whether an Anthropic-channel listing follows. See event log, Jul 10.
BambooHR Embedded AI assistant with citation-linked answers Multiple community implementations (encoreshao/bamboohr-mcp, evrimalacan/mcp-bamboohr, twentytwokhz/bamboohr-mcp, iseletsk/cl-bamboohr-mcp, plus a Go version for time-off), all 0–3 stars, all below threshold SMB HR market leader. High community interest (8+ implementations) but no vendor-published or high-quality community server. Candidate for fastest transition if any implementation crosses the star threshold.
HiBob Bob AI (mid-market HR) See Live section, MCP server now in shipped beta with read-write scope (create/update employee records, submit time off) via Claude desktop, Cursor, Copilot Studio, VS Code The V3 intent signal matured into a live capability: verified Jul 10 2026, live since at least Q2. Service-user-only access (no employee-level OAuth) is the governance model to watch. See event log, Jul 10.
Personio In-product AI features None verified European mid-market HR. Watch for DACH or UK moves.
Employment Hero Various AI features Zapier-bridged MCP only (not direct vendor MCP) APAC-first, expanding to UK.
Paychex Multiple in-product AI features Community demo server (ryanemitchell/paychex-mcp-server) not vendor-affiliated, documentation-focused, not data-access US SMB payroll incumbent.
Dayforce Dayforce AI Workspace (rolling out 2026), compliance monitoring, performance coaching, payroll anomaly detection Via Microsoft Copilot Studio partnership, not a standalone Dayforce MCP. CData commercial wrapper also available (Managed 3P). Hybrid case. Dayforce chose to distribute via Microsoft’s MCP ecosystem rather than publish its own. Worth watching whether this becomes a third path (ride a hyperscaler).

Confirmed absent from the MCP ecosystem entirely (verified 2026-04-11 via vendor search + GitHub + MCP registries): UK direct competitors (Access Group, IRIS, Zellis, Moorepay, Ciphr), construction payroll (Trayd, Miter, Lumber, Arcoro), Canadian SMB (Wagepoint, Payworks), US mid-market (Paycom), AI-native startups (Warp, Central HQ, Sira). No vendor-published MCP, no community MCP meeting threshold, no Anthropic partnership announcement. These categories will be checked on every scan, if any vendor launches, they will be added to Live or Transition Watch immediately.

Adjacent categories with MCP activity but outside HR&P core: SAP SuccessFactors (community only), PeopleSoft HCM (community Oracle-DB-backed), FactorialHR (European, community), Passgage (Turkish SMB, official but 1 star). Tracked for completeness but not shown in the matrix above.

What This Means For HR&P Strategy

The Category Has Split Three Ways

Open and distributed. Xero, Intuit, and Gusto. All three are accounting/payroll, not pure HR. All three moved before Q2 2026. Xero and Intuit took the highest-effort path (named Anthropic partnership plus published MCP). Gusto started with the lowest-effort path (MCP only, no named partnership) but has since been promoted to the Anthropic Connectors Directory, all three are now in Channel 2. All three are now visible in the market and generating social media attention.

Closed and fighting. Rippling, Paylocity, UKG. Building internal AI platforms with no external MCP distribution. This camp is thinning. Workday reversed course on June 2 2026 with MCP-based Agent-Ready Tools for external agents, and ADP began distributing curated partner-built agents through its own marketplace on March 2 2026. Workday’s CTO defection to Anthropic on April 9 had already shown the market’s verdict on the closed position: shares fell 6.5% to a six-year low in a single trading day.

Hybrid. Dayforce distributes AI capabilities via Microsoft Copilot Studio rather than publishing a standalone MCP server. Workday’s Agent-Ready Tools announcement on June 2 2026 points the largest HCM vendor in the same direction: external agent access over MCP, but governed by the vendor’s own security model and an Agent Passport attestation scheme. The hybrid path, marketplace reach without ceding the trust layer, now has the category’s biggest name moving toward it.

The Read-Only Consensus Is Broken

Until April 2026, the reference design for regulated vendors on AI marketplaces was simple: query layer in AI, transaction layer in vendor UI. Gusto pioneered this pattern. It was the safe, conservative blueprint that other payroll vendors were expected to follow.

Gusto itself has now abandoned it. The Claude Connectors Directory listing exposes calculate_payroll, submit_payroll, and run_payroll tools, eligible customers can execute payroll directly inside Claude. Combined with Xero’s full CRUD MCP and Intuit’s transaction-import capabilities, all three leading marketplace vendors now support write operations. The “query-only is the safe first step” thesis is no longer the industry consensus, it is last quarter’s thinking.

For any vendor still planning a read-only v1: the competitive bar has shifted. A read-only launch is still viable, but it will be perceived as behind the market rather than prudent.

Platform-Specific Experiences Are The New Bar

Intuit’s Claude Connector reveals a second strategic shift. The 11 tools in the Connectors Directory (profit-loss-generator, benchmarking-against-industry, industry-recommendation) are completely different from the 50+ CRUD tools in their open-source GitHub MCP server. Intuit built a purpose-designed financial intelligence experience for Claude, not a generic API wrapper.

This raises the bar for marketplace distribution. Simply exposing existing API endpoints as MCP tools may no longer be competitive. The emerging pattern is: build differentiated, platform-native experiences that leverage the AI’s conversational capabilities to deliver value that the vendor’s own product UI cannot. Intuit’s benchmarking-against-industry tool, which draws on aggregate data across millions of QuickBooks businesses, is a capability that only works inside an AI context, it is a new product, not a republished API.

The First-Mover Window Is Measurably Open

Twelve HR&P vendors on the transition watch list have in-product AI but no marketplace presence. None of them has a published MCP server, named Anthropic partnership, or Connectors Directory entry. The category of “first major multi-regional HR platform with a payroll compliance MCP” is currently empty. The regulatory moat is real, Anthropic’s native HR plugin handles offer letters and onboarding, but cannot replicate PAYE, CIS, auto-enrolment, multi-state tax, T4/ROE, or cross-border entity handling. Whoever ships first into this gap owns the category narrative for the next year.

The UK Cluster Silence

The most striking single observation from this audit is who is entirely absent. Every major UK direct HR & payroll competitor has zero marketplace presence, Access Group, IRIS, Zellis, Moorepay, and Ciphr. No vendor-published MCP. No Anthropic Connectors Directory listing. No named partnership. No community MCP above the quality threshold. No public intent signal. The entire UK direct cluster is silent.

This is a category-defining competitive gap. The UK mid-market HR&P segment, worth billions in ARR, dominated by PE-backed incumbents with deep compliance engineering, and feeding the entry-accounting upgrade path, is sitting on a narrative that is currently empty. The first UK vendor to ship a PAYE + CIS + auto-enrolment + multi-jurisdictional MCP server owns the UK category narrative for at least a year. The window is measurably open right now, and none of the obvious incumbents has made a public move.

Event Log

Time-ordered record of AI marketplace events that shape the HR&P competitive landscape. Updated after every strategy scan.

Jul 20–21 2026
The mid-market HCM tier ships agentic platforms as a bloc, and every one leads with the boundary. In roughly 48 hours, three mid-market HCM vendors launched named agentic-AI platforms. Paylocity Ignite AI (generally available, Jul 21) embeds named agents across HCM, finance and IT behind an "Ignite AI Hub" control plane, with "recruiters stay in control of every hiring decision"; it discloses no external model, so it stays internal. BambooHR Bamboo AI (private beta, Jul 21) spans HR, payroll, benefits and talent, adds MCP connections to ChatGPT and Claude on top of BambooHR's existing write-scope MCP, and frames its agents as bounded by existing permissions and an "employee context graph," with every action "traceable back to a person who's accountable." Netchex Mesh (early access, Jul 20) fields six named agents for the deskless workforce, accessible inside ChatGPT and Claude, where "nothing sensitive is submitted without human approval." The pattern is the story: agentic HCM is now table stakes at the mid-market, so the governance surface (a control plane, a permission-scoped attestation graph, a human-approval gate) is the differentiator, not the agents themselves. Every payroll-facing agent in the cluster analyses, checks or flags the payroll and stops one step short of running it. On the same day, Morgan Stanley downgraded Workday to Underweight over "gradual" AI monetization; everyone ships, the market is asking who gets paid.
Jul 20 2026
Workable widens its agent connector to the full HR lifecycle, still scoped to the user. Workable expanded its Model Context Protocol server from 57 to 94 tools, adding advanced candidate and employee search, the full 15-tool performance-review lifecycle, account and permissions management, and candidate-profile write access, across Claude and ChatGPT. The governance line held: "every MCP session is scoped to the authenticated user's existing role and access within Workable. AI assistants can only read and act on data the user is already authorized to see." This is the third user-scoped-write connector in four days, after Omni HR and BambooHR, and the notable part is that it extends the model across the performance-review lifecycle, a sensitive, judgement-laden surface. The differentiator is the permission model, not the tool count.

The write-scope governance middle path ships, from an emerging vendor. Omni HR, an APAC-origin unified HR and payroll platform, launched a vendor-published MCP connector letting AI agents read and act on live HR data from Claude, ChatGPT and Cursor, across employee data, lifecycle management and time off. It is read-write: agents can update employee profile data, not only query. The distinguishing feature is the permission model. Every action the agent takes is scoped to what the authenticated user is already authorised to see, with no new access granted and no HR data stored at the connector, so that in the vendor's words "your access controls travel with the data. The AI doesn't get a bigger view of your business than the person operating it." That places Omni on the governance middle path between two July poles: HiBob's write-by-default connector authenticated on a shared service-account token (the audit trail resolves to a service account, not a person) and Symmetry's read-only tax engine (structurally unable to act at all). Omni ships write capability with per-person attestation, the property a regulated buyer actually wants, and did so before the largest platforms. Channel 3 (custom MCP), early access; payroll modules not yet in MCP scope. It also marks Omni's pivot from the internal-AI camp (the Mino agent, June 8) to external agent distribution.

The compliance layer goes agent-callable, and bets read-only. Symmetry, the payroll-tax calculation engine embedded inside Gusto, UKG and Paychex (it calculates paychecks for more than 64 million US and Canadian employees a year), launched an MCP server exposing its engine to AI agents: federal, state and local tax determination for any US address, real-time multi-state and year-to-date-aware pay calculations, gross-ups, benefit limits and filing rules. The defining constraint is what it will not do. The logic is exposed through a read-only interface that, in Symmetry's words, "cannot mutate payroll runs, client data, or tax rules." This is the first infrastructure-supplier MCP tracked here: every prior HR&P entry was a vendor exposing its own product so an agent could act on it, while Symmetry, the layer sitting underneath several of those vendors, arms the agents above it with a correct-by-construction tax tool and forbids them to act. It is the counter-pattern to the write-scope wave (Gusto, HiBob, Deel) and the first clean answer to the accuracy problem under agentic payroll: with frontier models scoring roughly half on real finance tasks, a deterministic tool the agent merely calls beats a model asked to compute withholding. The first platform customer using it is UZIO. Channel 3 (custom MCP), US and Canada only, so the equivalent read-only tax tool for the UK and other markets is still unclaimed.

HiBob's MCP server is live in beta, and it writes. The July 10 audit verified that HiBob's vendor-published MCP server has moved from intent signal to shipped beta: agents connected through Claude desktop, Cursor, Microsoft Copilot Studio or VS Code can find and view employee records, create and update them, access time-off balances and submit time-off requests, and manage tasks. Access is restricted to Bob service users under permission-group controls (Basic-Auth tokens; no employee-level OAuth yet). The page is undated and changelog metadata suggests the beta has been live since at least the second quarter of 2026. Channel 3 (custom MCP), not listed in any Anthropic directory. This makes a fourth transactional, write-scope agent surface below the enterprise tier, after Gusto, the May 13 mid-market ATS MCP and Workday's Agent-Ready Tools early access; service-account-only access is currently the thinnest governance model in that cohort.
Apr 24 2026 (verified Jul 10)
Deel has been live in ChatGPT since April. The July 10 audit caught a missed launch: the Deel App for ChatGPT, an MCP-based app in OpenAI's apps channel with three access tiers. Anyone can query global hiring costs, employer-cost and take-home comparisons across 150+ countries without an account; authenticated Deel clients can start contracts, approve requests and track onboarding from chat; workers can check onboarding status, pay and benefits. Deel describes the underlying compliance base as maintained by hundreds of local legal experts across more than $22B in annual payroll. Deel remains absent from Anthropic channels, making it the clearest case yet of a major HR and payroll vendor choosing the OpenAI channel first.

isolved enters the Anthropic Connectors Directory and ships six autonomous agents. At SHRM26, isolved launched general availability of its Connector for Claude in the Anthropic Connectors Directory (Channel 2) and introduced six named agents built to own HR, payroll and benefits outcomes, phased across 2026 and 2027: The Guardian (flags payroll errors before the run closes), The Advisor (benefits enrollment), The Signal (retention risk), The Orchestrator (cross-system onboarding), The Watchdog (multi-state regulatory change) and The Helper (24/7 employee HR questions). isolved frames this as a new "Workforce Capital Management" category for managing human and agentic workers side by side. It is the first SMB and mid-market HCM incumbent of this scale to take the Anthropic-direct marketplace path rather than keep its AI behind its own product, a direct counter to the Workday, ADP, Paylocity and UKG internal-AI camp. The Guardian, a named pre-run payroll-error agent, is the most strategically pointed of the six.
Jun 4 2026
Abacor launches an MCP connector for Claude. Abacor, a meeting-context platform for accountants and advisors, shipped an MCP connector that captures meeting summaries, action items, transcripts and decisions, and chains with existing Intuit QuickBooks, Xero and Microsoft 365 connectors. Channel 3 (custom remote MCP). Accounting-advisor adjacent rather than a core HR and payroll competitor, logged for completeness as the advisor tooling layer continues to wire into Claude.
Jun 10 2026
Lattice announces an MCP server. The performance management platform announced an MCP server on June 10 2026, extending the mid-market MCP wave from payroll and recruiting into the performance suite category. Tool scope and architecture are not yet publicly documented; this entry will be expanded when details ship.
Jun 9 2026
ZipRecruiter expands AI job search through a Claude integration. Announced June 9 2026. A recruiting marketplace now distributes job search inside Claude, alongside the payroll and accounting vendors already shipping on the AI platforms. Candidate-side job matching in an assistant surface is a different wedge from the admin-side payroll and HR integrations tracked above, but the distribution logic is the same: meet users inside the AI tool rather than pull them to the vendor site.
Jun 8 2026
Omni HR launches Mino, an AI agent for multi-country HR and payroll across APAC. Announced June 8 2026, in early access. Mino operates on unified multi-country HR and payroll data with sub-agent coordination. This is in-product AI rather than marketplace distribution, logged because it adds a new vendor to the internal-AI camp and because unified multi-country payroll data under an agent is exactly the regulated depth that generic platform plugins cannot replicate.
Jun 4 2026
Remote formally launches its MCP server. As of June 4 2026, any AI agent can hold a live, secure connection to Remote’s payroll, contracts, compliance, and org-structure data with no API keys. Announced inside a results sweep in which Remote ranked first in all four company segments of G2’s Summer 2026 Global Employment Platform category, with payroll revenue up 300% year over year, more than $300M in ARR, and cash-flow positive operations. Remote is positioning as the employment-data engine underneath other platforms’ agents.
May 13 2026
Workable launches an official MCP server. 38 tools, read and write, spanning recruiting plus HR including employees, time tracking, and time off. OAuth2 with role-scoped sessions, free on all plans, works with Claude and ChatGPT. An ATS-HRIS shipping a transactional MCP surface at no charge follows the pattern Gusto set: agents can query and act on the data, not just read it. The MCP wave has reached the recruiting-led mid-market.
Apr 12 2026
Gusto promoted to Anthropic Connectors Directory with transactional payroll. Gusto’s Claude integration upgraded from Custom Remote MCP (Channel 3) to the curated Connectors Directory (Channel 2). Tool count expanded from 36 to 41, now including calculate_payroll, submit_payroll, and run_payroll. “Eligible customers can also run payroll in Claude.” The read-only consensus for regulated vendors on AI marketplaces is now broken. Going viral on Twitter/X.
Apr 12 2026
QuickBooks Connector live in Anthropic Connectors Directory with differentiated financial intelligence toolset. Intuit ships a purpose-built 11-tool connector for Claude that is entirely different from its open-source CRUD MCP server. Tools include P&L generation, cash flow analysis, industry benchmarking, and recommendations, a financial advisory service, not a data access layer. Accepts CSV/PDF/image transaction uploads. Signals that winning on AI marketplaces requires building platform-specific experiences, not republishing APIs.
Apr 8 2026
Gusto launches payroll inside Claude and Slack. First major payroll vendor to ship on a second AI marketplace after its ChatGPT launch in January. Natural language payroll queries available inside Claude via custom remote MCP connector. Subsequently promoted to Connectors Directory with transactional capabilities (see Apr 12 entry).
Mar 2026
Xero and Anthropic announce multi-year partnership. Bi-directional Claude integration. JAX “financial superagent” inside Xero powered by Claude reasoning. Xero data accessible inside Claude.ai for business planning. Rollout “in the coming months.” Official Xero MCP server active on GitHub.
Feb 24 2026
Anthropic launches Claude Cowork plugin ecosystem. Nine enterprise function plugins including Human Resources, Finance, Operations, Engineering, Design. Plus 10+ enterprise MCP connectors (Google Workspace, DocuSign, FactSet, MSCI, LegalZoom, Harvey, Apollo). Plus private plugin marketplaces for enterprise customers.
Feb 24 2026
Intuit and Anthropic announce multi-year partnership. Custom AI agents for mid-market via Claude Agent SDK. Intuit financial intelligence surfaced inside Claude, Cowork, and Claude for Enterprise. MCP integrations for QuickBooks, TurboTax, Credit Karma, Mailchimp. Claude Code deployed across Intuit engineering. Parallel $100M+ OpenAI contract continues.
Jan 20 2026
Gusto launches payroll inside ChatGPT. First enterprise-grade payroll app in OpenAI’s business app directory. OAuth-secured, admin-only enablement. Natural language payroll queries and trend analysis. The start of Gusto’s multi-platform plugin distribution strategy.
Nov 2025
Microsoft Dynamics 365 ERP MCP Server reaches general availability. 650,000+ operations accessible to AI agents across Finance, Supply Chain, Human Resources, and Project Operations. Full CRUD. First hyperscaler-scale enterprise platform accessibility commitment.
Oct 2025
Intuit publishes QuickBooks Online MCP server on GitHub. Early Preview. 128 stars, 55 forks, Apache-2.0. CRUD operations across accounts, bills, customers, employees, invoices, items, vendors. The most-starred HR/payroll MCP server on GitHub.
Jul 14 2025
Anthropic launches Claude Connectors Directory. Curated MCP servers at claude.ai/directory. Launch partners: Notion, Stripe, Canva, Asana, Atlassian, Intercom, Figma, Gmail, PayPal, Square. No HR/payroll vendor at launch, and none added since as of this audit.

Methodology

Update Cadence & Provenance

This page is maintained as a running log and refreshed regularly. Updates include checks of the Claude Plugin Directory, the Anthropic Connectors Directory, OpenAI’s Business Apps directory, and targeted vendor searches. New launches are added as they surface.

Community MCP threshold: a community-published server is included on this page only if it meets at least one of: (a) ≥100 GitHub stars, (b) listed on a major MCP registry (mcp.so, glama.ai, smithery.ai, mcpservers.org, modelcontextprotocol.info), or (c) documented maintenance in the last 90 days plus demonstrable usage. Commercial third-party wrappers (CData, StackOne, Knit, Composio, Unified.to) are tracked separately under “Managed 3P” status.

Intent signal (new category, added V3): a vendor-attributed public MCP repository is treated as a distinct signal type even when the code is minimal or empty. The reasoning: no one accidentally publishes a public [vendor]-public-mcp under an official GitHub organisation. Doing so requires internal approval, legal review, developer advocacy sign-off, naming priority over the community, and public commitment to maintenance. The act of publishing is a strategic commitment signal, even when the capability is still in development. HiBob’s repository is the first tracked example. Future intent signals will be called out separately from shipped-and-mature vendor MCPs.
