MCP connectors by dev.tango

Tango gives your agent structured, real-time access to the entire federal procurement graph — contracts, opportunities, entities, IDVs, OTAs, protests, subawards, forecasts, budget accounts, vehicles, and GSA eLibrary — behind one auth boundary. No screen-scraping, no stitching together government APIs. Five tools (search, search_opportunities, resolve, get_details, fetch_api_docs) work from Claude, Cursor, the OpenAI Responses API, or any MCP client.

MCP access to the U.S. federal procurement graph: contracts, opportunities, entities, and more.
