Why these MCPs

  • Tested. 5,457 collected regression tests, including live-API tests, across 9 servers and 133 tools, with up to ten audit rounds per server against the live government APIs. Published testing records document each bug fixed and the tests added.
  • Listed, no keys. 4 servers in the Claude directory and 3 in the ChatGPT directory, with all nine planned for both. Directory installs need no user API key.
  • One of a kind. The only known MCP server for Acquisition.gov FAR Overhaul model text and agency class deviations.

Available in Claude and ChatGPT

All nine MCPs install and run locally today; the Local column links to each setup guide. Four are also published in the Claude directory and three in ChatGPT, where installs need no user API key or local setup. The rest are coming soon to the directories.
