TaxMCP connects Claude to a searchable tax-law knowledge base covering the Internal Revenue Code, Treasury Regulations, IRS publications and guidance, U.S. Tax Court opinions, and supported state tax statutes. Seven read-only tools let users search tax topics, retrieve exact sections and source documents, explore cross-references, and review case citation activity. Results include source metadata and citation URLs so tax professionals can verify the underlying authority. Federal search is available on all plans; case law, advanced guidance, and state-law access depend on the connected TaxMCP plan.
