Research tool, not professional advice

taxmcp.io, operated by Gray & Company LLC, is a tax research tool. It returns excerpts and citations from the Internal Revenue Code, Treasury Regulations, IRS Publications, Revenue Rulings, IRS Notices, and state tax codes. The content surfaced by the service is the underlying primary source material.

taxmcp.io is not a substitute for professional tax, legal, accounting, or financial advice. Nothing on this site or returned by the MCP server constitutes such advice, and no attorney-client, CPA-client, or fiduciary relationship is formed by using it.

No reliance

Tax law changes frequently. While we refresh the corpus regularly against official government sources, taxmcp.io makes no warranty that results are current, complete, or free from error. AI tools that consume this data may also summarize, paraphrase, or misstate it.

Before acting on any output from taxmcp.io, verify it against the cited primary source and consult a qualified tax professional licensed in your jurisdiction.

AI-generated answers

taxmcp.io provides structured data to AI clients (Claude, ChatGPT, and any other MCP-compatible client). The natural-language answers shown to you are generated by those AI models, not by taxmcp.io. Like any AI output, those answers can be incomplete or wrong even when the source material is correct.

Every tool response from taxmcp.io includes a citation URL back to the primary source. Always check it.

Practitioner use

If you are a CPA, EA, attorney, or other tax professional, you remain solely responsible for the work product you deliver to your clients, including the accuracy of any research performed via taxmcp.io. Use of the service does not modify your professional, ethical, or regulatory obligations.

Jurisdiction

taxmcp.io covers U.S. federal tax law and a growing set of U.S. state tax codes. It does not cover foreign tax law, treaty interpretation, or non-U.S. jurisdictions. State coverage is listed on the homepage and may change over time.
