eCFR

Overview

eCFR is a Model Context Protocol (MCP) server: Electronic Code of Federal Regulations including FAR and DFARS. 13 tools. In practice that means any MCP-compatible AI assistant can call eCFR's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Python package ecfr-mcp (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.6, published under the MIT license, with source at 1102tools/federal-contracting-mcps on GitHub, where it has earned 20 stars.

eCFR is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
