Sam Gov MCP Server

The most comprehensive keyless-first MCP server for US federal and state/local (SLED) contracting + spending + regulation + partner vetting. 150 tools across 52 data sources - keyless-first: only 4 sources (Census business-patterns, FRED, BEA, and DOL's data endpoint) need a free key; the other 48 need none. Works today, in any AI agent. Its 40 documented tools cover usas, sam, spending, awards.

People connecting API integration tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

Claude Code

claude mcp add cliwant-mcp-sam-gov -- npx -y @cliwant/mcp-sam-gov

Claude Desktop / Cursor / VS Code - add to config

      "args": [
        "-y",

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can extract attachment text (RFP / SOW / Q&A / wage tables) from PDF + DOCX + text/HTML, resolve 'VA' / 'DHS' → canonical toptier name + 4-digit code, and navigate the NAICS tree (2→4→6) + active-contract count per code.
