Koskamo

MCP Observatory MCP

A free, MIT-licensed security testing tool for Model Context Protocol (MCP) servers. It allows developers to scan, audit, and compare MCP servers locally or in CI pipelines. Features include schema drift detection, attack simulation, health scoring, and SARIF report generation. It also supports runtime enforcement via mcp-seatbelt to block dangerous tool calls based on scan results.
