post/mcp-registry/v1/server_detail1 credit

Full merged profile for one MCP server across every registry it appears in: manifest (tools/capabilities/transport), install paths (packages/remotes/connections), license, GitHub repo health, and cross-registry presence (how many registries list it = trust signal).

Working example
Parameters

A GitHub URL/slug (owner/repo), a Smithery qualifiedName, a Glama id, or an Official registry name. github_url is the most reliable (it joins all registries).

Include GitHub repo-health enrichment (stars/issues/archived/license). Default true.
