Koskamo

MCP Security Guard

A local security auditor for Model Context Protocol (MCP) servers that detects tool poisoning, rug pulls, tool shadowing, hidden Unicode, and leaked secrets. It maps findings to the OWASP MCP Top 10 and operates locally to ensure nothing leaves the machine unless opted in. It supports integration with Claude Code, Cursor, VS Code, and GitHub Actions.
