I monitored 11 public MCP servers. Latency ranged 215 (97ms to 21 seconds).
A developer has created a tool to monitor the performance of public Model Context Protocol (MCP) servers, revealing a significant latency spread from 97ms to 21 seconds across 11 monitored servers. The tool, which speaks the MCP protocol (JSON-RPC over HTTP), also identified a critical issue: contract drift, where servers silently alter tool schemas or disappear without failing HTTP status codes, causing agents to break. The developer offers a live index and an open-source CLI for MCP server monitoring. AI
