Tango

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

What does this entry provide?

Tango is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 93/100. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding Tango to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.
