Live data from nothumansearch.ai/digest.json — free public API, no auth, refreshed on every crawl cycle.
Of 5,418 sites that advertise MCP / agent-ready signals, only 725 (13.4%) survive a real JSON-RPC handshake to their /mcp endpoint. The rest either return HTML, time out, or never implemented the protocol correctly.

NothingHumanSearch crawls submitted URLs and auto-discovered candidates from public sources (awesome-mcp-servers, PulseMCP, llmstxt.site, curated feeds), then scores each site against seven weighted signals: llms.txt present and parseable; ai-plugin.json at /.well-known/; an OpenAPI or AsyncAPI spec at a discoverable path; an MCP manifest; a live JSON-RPC MCP handshake; documented rate-limit and auth headers; and an accessible structured API response. Sites are re-crawled weekly. Scores range 0–100; any score above 75 corresponds to a site an autonomous agent can realistically integrate without human help.
Verification means a TCP connection + HTTP POST to the declared /mcp endpoint with a JSON-RPC 2.0 initialize request, followed by a valid result response containing a protocolVersion. Sites that host a manifest but fail the handshake are counted in the index total but not in the MCP-verified total.
