OpenAccountants Marketplace

83 Claude Code plugins for tax & accounting — verified by named licensed accountants.

One install command gets you the full marketplace. Every plugin is a thin router to the hosted OpenAccountants MCP server, which holds 1,889 verified skills across 190+ jurisdictions and an AI-to-verifier handoff tool that books you onto a real accountant's Calendly when you're ready to file.

Install

claude plugin marketplace add openaccountants/marketplace

Then browse and install any plugin from the /plugin menu in Claude Code:

/plugin install openaccountants-mt          # Malta (verified by Michael Cutajar, CPA)
/plugin install openaccountants-za          # South Africa (verified by Werner Britz, CA(SA))
/plugin install openaccountants-us-ca       # California
/plugin install openaccountants-crypto-tax  # Crypto, cross-jurisdiction
…

Or just install the base plugin and let it route everything:

/plugin install openaccountants

How each plugin works

Every plugin is the same shape:

plugins/<slug>/
├── .claude-plugin/plugin.json    # plugin manifest
├── .mcp.json                     # routes to openaccountants.com/api/mcp
├── skills/<slug>/SKILL.md        # auto-invoke trigger
├── commands/                     # 3 slash commands per plugin
│   ├── start.md                  # /start — scope your question
│   ├── skills.md                 # /skills — list everything in scope
│   └── review.md                 # /review — book a real accountant
└── README.md

The plugins themselves are light — they're routers. The actual rules, rates, and computation logic live on the hosted MCP server, which means:

• One source of truth across 83 plugins
• Annual rate refreshes propagate instantly to every plugin
• Verifier sign-offs flow through automatically

The handoff is the differentiator

Every plugin includes the /review slash command, which calls the MCP's request_accountant_review tool. When you're ready to file, the AI:

1. Captures your working paper (classified transactions, computations)
2. Routes the request to the named lead verifier for your jurisdiction (e.g. Werner Britz CA(SA) for South Africa, Michael Cutajar CPA for Malta)
3. Returns a Calendly link the user can book directly

The verifier sees the scenario + the worksheet before the call. No client-accountant relationship until both sides sign an engagement letter.

Regenerate

The marketplace is auto-generated from the OpenAccountants source repo. When new skills land or jurisdictions are added:

node scripts/generate.js

This rebuilds the plugin folders + marketplace.json from the current skill catalogue. Plugins below the minimum skill threshold (MIN_SKILLS_PER_PLUGIN = 3) are skipped.
