Connects Claude to 890+ accounting skills covering tax, bookkeeping, payroll, and financial statements across 134 countries, all 51 US state packages, and 13 Canadian province packages. The project runs on a two-layer model: research-verified drafts live in the GitHub repo under AGPL-3.0, while accountant-signed skills (Tier 1, with named CPA/CA verification) are served through the MCP at openaccountants.com. Every verified output includes the credentialed accountant's name, and the request_accountant_review tool routes users to a real practitioner with context attached. Coverage is uneven: thirteen countries ship the full suite, many others are VAT-only or partial. Install the connector at openaccountants.com/connect or audit the research layer on GitHub before you trust any calculation.
