Irs Taxpayer

Overview

Irs Taxpayer is a Model Context Protocol server that puts 39 tax calculation tools directly into your AI assistant. It covers federal and state income tax, tax credits, deductions, retirement planning, and more for US taxpayers. When you use it with Claude, Cursor, VS Code, or any MCP-compatible client, the AI can call these tools automatically during conversations to help with tax questions and calculations.

The server runs entirely on your machine using the npm package irs-taxpayer-mcp. Installation is simple: npx -y irs-taxpayer-mcp. No authentication or API keys are needed, and all processing stays local. Version v0.5.3 is available now under the MIT license, with source code at dma9527/irs-taxpayer-mcp on GitHub.

You'll find Irs Taxpayer listed in the AI & Agents category on mcp.site. It works seamlessly with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim your listing here to verify ownership and keep information up to date.
