Where does the catalog come from?
Live public sources, merged and deduped by domain + endpoint: the official MCP registry, PulseMCP, Glama, Smithery, GitHub topics, and the x402 Bazaar. Records land raw at T0 and climb only by being probed — there is no synthetic filler; sample records, when present, are banner-labelled. The whole index is downloadable at /v1/agents.json.
