For AI assistants

The Contrax MCP server

Ask an AI assistant which federal contracts are about to end, and get an answer from public records. Contrax runs a free, read-only connection (a Model Context Protocol server) that any assistant supporting MCP can use. No account and no key.

Address

https://www.contrax.company/api/mcp

Transport: streamable HTTP. In Claude, add it as a custom connector. In other assistants, add it wherever remote MCP servers are set up.

Tools

• contracts_ending_soon · Federal contracts ending soon

  Federal contracts in one line of work whose end date falls in the next 12 months in one US state: how many, their combined award value, how many companies hold them, the typical award size, the largest ones ending within 6 months, the agencies and companies with the most, and open bids that fit. Source: USAspending.gov records gathered by Contrax. An ending contract is not a promise that the work will be rebid.

• list_trades · Lines of work Contrax tracks

  The lines of work (trades) that contracts_ending_soon accepts, with their plain names.

Lines of work: Janitorial, Security guard, Trucking and hauling, Landscaping, Construction, HVAC and plumbing, Electrical, IT services, Cybersecurity, Waste and trash hauling. States: all 50 and DC, by two-letter code.

Things to ask

• Which federal janitorial contracts are ending in Virginia in the next year, and who holds them?
• What were federal HVAC contracts in Texas typically awarded for?
• Which agencies have the most IT services work ending in Maryland?

What it returns, and its limits

• Totals for the market, the typical award size, and up to 5 rows of each list, with a link to the rest.
• Source: USAspending.gov contract records. An end date can move if an agency extends a contract, and an ending contract is not a promise of a new solicitation.
• Read-only. It takes a state and a line of work and nothing about you.
• 40 data calls an hour from one address.
