Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Open Policy Agent (OPA) and Rego policy toolkit. 32 tools spanning authoring (format, lint, check, deps), evaluation (eval, test, bench, coverage), and OPA REST control (policies, data, decisions, compile). Wraps the OPA CLI and the Regal linter, with AI-assisted helpers for explaining decisions, generating test skeletons, and suggesting fixes.
Runtime governance for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.
