About TaxMCP

Give the AI you use a path to the tax authority.

TaxMCP is a hosted research connector for CPAs, enrolled agents, tax attorneys, and small firms. It retrieves source-linked tax authority inside Claude, supported ChatGPT plans and workspaces, and other MCP-compatible clients.

A source layer

TaxMCP retrieves primary authority and returns links that a professional can open and inspect. It does not replace the judgment required to apply that authority.

Inside your assistant

The product is delivered through Model Context Protocol, so the research step can stay inside the AI environment where a practitioner already frames questions and drafts.

Clear boundaries

TaxMCP is research software, not tax-preparation software, legal advice, a validity citator, or a substitute for reading authority in context.

What We Cover

Research that starts with the underlying text.

The corpus includes the Internal Revenue Code, Treasury Regulations, selected IRS publications and guidance, supported state tax codes, and U.S. Tax Court opinions available by plan.

TaxMCP is built and operated by Gray & Co. Product pages and articles are maintained by the TaxMCP Editorial Team under our published editorial standards.

Questions about coverage, corrections, or the product can be sent through the contact page.

Inspect the source before you rely on the answer.

Start with the free IRC tier, then add the federal, state, and case-law sources your practice needs.
