Koskamo

OPA MCP

An open-source Model Context Protocol server that provides over 50 tools for authoring, validating, debugging, and explaining Open Policy Agent (OPA) Rego policies. It integrates with MCP-compatible clients like Claude, Cursor, and VS Code, bundling the OPA binary for ease of use without separate installation.
