AgentSearch

Find AI agents and MCP servers by natural-language query. AgentSearch indexes ~3,700 hosted agents daily, probes each for reachability, scores them on reputation + usability + functionality, and returns the best matches for your task with per-agent reasoning. Use it to answer 'is there an agent that does X?' or 'is this specific agent any good?'. Read-only, free, no auth.

Skills

Search the agent index

Take 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.

Examples:

find an agent that reads invoice PDFs

what MCP server lets me control a browser

agents for crypto price lookup

Get a scored agent profile

Return 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 URL

Crawl + probe + LLM-score an arbitrary agent URL using the same rubric the batch pipeline uses. Works for agents not (yet) in the index.

Examples:

score https://github.com/example/new-mcp-server

evaluate https://some-new-agent.com against the query 'edit calendar events'

is https://acme.com/agent/api any good?
