Overview

AI-generated overview

Lets an assistant look up US federal tax figures together with the IRS document each number comes from.

What it does
This remote MCP server provides US federal tax numbers and cites the IRS document each figure is drawn from. It is hosted at a fixed endpoint and is described as helping get those numbers right. No individual tools are listed in the supplied material.
When to use it
Worth adding when an assistant needs US federal tax figures and the IRS source behind them, for example while preparing or checking tax-related answers. Not intended for state, local, or non-US tax questions.
Requirements
A remote MCP client that can connect to a streamable HTTP endpoint. No packages, environment variables, headers, or authentication are declared, so nothing else appears to be needed beyond network access.
Before you install
The description says the numbers come with their IRS source, but no tool list, versioning, or update policy is provided, so figures may be outdated or incomplete. Verify any number against the cited IRS document before relying on it, especially for filing or payment decisions.
