MCPulse

Analytics for MCP servers

MCPulse is an npm SDK that instruments MCP servers to measure how AI agents use their tools. It records per-tool call counts, first-call success rate, retries, empty answers, tool errors, crashes, latency, response size, schema cost, and dead tools. It runs inside the server process rather than as a proxy, records only sizes, timings, and one-way hashed fingerprints of arguments — never arguments or results. Includes a client-side schema checker that scores tool definitions against a corpus of 4,749 public MCP servers, plus API and MCP connector access to the data.
