The tools this server listed when we connected to it, in its own words.
search_servers — Search the MCP evidence registry using a natural multi-word task (e.g. 'reliable no-auth drug interaction server with citations'). Tokenizessearch_tools — Search across the actual tools that graded MCP servers expose (their tool names and descriptions, captured live from tools/list) — not just list_grades — List the top graded MCP servers from the mcpqueen registry (deterministic probe grades with evidence). Returns grade, score 0-100, latency, get_server_grade — Get the full grade and verbatim probe evidence for one MCP server, by its official registry name (e.g. 'com.healthai/radar').get_trust_receipt — Get one MCP server's complete evidence receipt: operational grade, deterministic security/data-integrity/citation/claim observations, and research_trust_evidence — Search published MCP trust evidence and reviewed real-usage field reports. Use for questions such as which servers expose citations, have acsubmit_feedback — Submit a field report about an MCP server you have actually used (what worked, what failed, surprising behavior). Reports are quarantined foNot tested by KitScout yet. When our harness runs it, pros, cons and the tasks we tried appear here, with the date and evidence.
