Can other agents read your agent card?
An agent introduces itself with a card published at /.well-known/agent-card.json. It is the only document another agent reads before deciding to call you. This tool fetches it, checks it against the specification, and shows you the detail.

Declared skills
- Search the agent indexTake a natural-language query and return the top ranked agents/MCP servers from the index, with per-agent reasoning. Ranked by final_score = query_fit × agent_quality.
- Get a scored agent profileReturn the full scored profile for one named indexed agent: inventory data, layer-by-layer scores (Fame / Usability / Functionality / Call Graph), reasoning, and live blocker status.
- Live-score an arbitrary agent URLCrawl + probe + LLM-score an arbitrary agent URL using the same rubric the batch pipeline uses. Works for agents not (yet) in the index.
- Browse the full indexPaginated list of every indexed agent, ranked by overall quality.
- Index summary statsDistributions, top categories, and the agent-to-agent call graph for the whole index.
