Partnertax.aiMCP

Plug in. Ask the law.

PartnerTax MCP connects our library of U.S. federal and state tax law to Claude and any MCP-compatible assistant. Your AI searches the actual statutes, regulations, and IRS guidance — and cites the official source for every answer.

What your assistant can do with it

Three tools, available in every conversation once the server is connected.

Search tax law

Ask in plain English. Your assistant searches the indexed corpus and returns the most relevant passages, each with a citation and a link to the official source.

Read the full section

Pull the complete text of any statute, regulation, or form instruction the search surfaces — so answers rest on the actual law, not a summary of it.

See what's covered

List every jurisdiction and body of law in the library, with live section counts, so you always know what the answers draw from.

What's in the library

U.S. Federal

Internal Revenue Code (Title 26), Treasury Regulations (26 CFR), IRS forms & instructions, publications, curated guidance, and the Internal Revenue Manual.

All 50 states

Statutes, regulations, and form instructions for every state, where each is publicly available. Ask your assistant to list jurisdictions for the live section counts.
