Not Human Search

ai.nothumansearch/search

This is the MCP interface to Not Human Search's index of 4,100+ agent-ready sites. You get 11 tools including search_agents to query by category or protocol, get_site_details to pull readiness scores and signal breakdowns, check_url to validate endpoints before calling them, and verify_mcp to probe MCP servers for liveness. It also exposes get_stats for index metadata and submit_site if you want to add URLs programmatically. Useful when your agent needs to discover APIs, find services by capability, or verify that a third-party MCP server is actually responding before wiring it in. The probe-before-use tools are the standout here: they let you build agents that validate their own tool chain at runtime instead of failing mid-task.
