MCP Measure, an evidence ledger for MCP servers

mcpmeasure.com Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

A timestamped index tests Model Context Protocol servers by installing them, completing an initialize handshake, and enumerating their available tools.

Landing page captured for the 2026-09-17 issue.

Field notes

MCP Measure runs a disposable test sequence against server packages: installation, MCP initialize, and tools/list, while deliberately avoiding tool execution. The homepage displays repository identifiers, observation timestamps, authentication status, and tool counts for examples such as KnownFix and AgencyAI Commerce MCP. It reports 14,890 indexed servers and 652 currently verified, with records treated as stale after 30 days. The site distinguishes protocol evidence from security review and endorsement.
