find_servers
Find MCP servers
Find a compact, trust-aware shortlist for a task or capability when no particular MCP server or product is known. Search by free text or MCPLookup's normalized capability taxonomy, with optional filters. Free text returns a reviewed identity-only slate when available; otherwise results are explicitly labelled catalog matches, and the two evidence lanes are never mixed. Returns at most five results with no pagination. A selected exact server name can be passed to resolve_server for reviewed identity context and connection options; named artifacts fit resolve_server directly.

resolve_server
Resolve an MCP server
Resolve a named MCP server, vendor, product, package, repository, Registry identifier, or endpoint to a canonical MCPLookup identity. Returns at most five reviewed candidates with query-relative identity and publisher explanations, a compact trust assessment, and current connection options. This is the best fit when a particular artifact or product is known; find_servers covers open-ended capability discovery, while trust_lookup returns the full current evidence record for an exact canonical name.

trust_lookup
MCPLookup trust lookup
Return MCPLookup's complete current trust record for one exact canonical MCP server name. Includes the verdict, Trust Index band and 0–100 score with confidence, coarse safety, maintenance, adoption, and provenance bands, coverage, freshness, public evidence, and citation. This fits trust questions and evidence review after identity is known; resolve_server handles ambiguous names or coordinates. Current state only—no history or safety certification.
