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.
Primary authority on demand
TaxMCP retrieves primary authority and returns links a professional can open, inspect, and use with confidence in a well-documented research process.
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.
Focused by design
TaxMCP is purpose-built for tax research. That focus keeps primary authority visible while the professional applies judgment, checks context, and owns the conclusion.
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., which maintains the site's product pages and articles.
Questions about coverage, corrections, or the product can be sent through the contact page.
Editorial Methodology
Built around sources you can inspect.
TaxMCP product pages and articles identify the relevant authority, link to official sources where available, and distinguish retrieved source material from the connected assistant’s explanation.
We update product and coverage information as it changes. TaxMCP articles are published by TaxMCP for educational research support; readers review cited authority in context and apply professional judgment.
