What it does
OpenAccountants MCP gives an assistant tax reference material organized by jurisdiction. Rates, thresholds and deadlines link to official sources. Users select the relevant country or region and ask questions through their AI client. Review levels vary: some materials have a named accountant’s review, while others were checked against legislation without that sign-off. A hosted connector and a self-hosted Python server are available. Review status can be inspected before relying on an answer.
Who it is for. Accountants and international business owners collecting initial tax references for a specific jurisdiction.
Good fit when
- Before speaking to a local professional, you gather rates and deadlines with sources.
- An assistant should explain a tax term using the selected country’s materials.
- You want to open the official source behind each figure in an answer.
- For a single country, you want to give your assistant a separate reference-file package.
Not a fit when
- An answer would be used to file a return without professional review.
- The collection lacks material matching your situation.
- You assume a named author necessarily means a licensed accountant reviewed it.

Limitations
Materials may be outdated or incomplete for your facts; have a qualified professional check outputs before filing or paying. Not every reference has an accountant’s review, so inspect the status and review record of the exact version. Hosted queries reach OpenAccountants; omit unnecessary client details from questions. Server code and skill content use different licenses, so review the content’s commercial-use terms separately.
How to disable. Remove the OpenAccountants connection or stop your self-hosted MCP server. Previously saved answers and downloaded references remain.
FAQ
Which address should I add?
Use `https://www.openaccountants.com/api/mcp`; the project’s connection page provides guided setup.
How do I identify the reviewer?
Check `reviewed_by` and the public reviewer roster. Authorship alone does not establish professional review.
Can I load just one country?
Yes. Download its folder from `packages/` and give the files to your assistant, starting with the main country package.
How do I report an incorrect figure?
Open an issue with the official source that demonstrates the discrepancy.
Where do I check the reference materials’ usage terms?
Read `LICENSING.md` and, for commercial use, `COMMERCIAL-LICENSING.md`. The server-code license does not define the terms for reference content.
