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.

Enforces YAML-configurable policies (blocklists, rate limits, token budgets), tracks real token costs via tiktoken, monitors server health with live JSON-RPC probes. Features include OAuth 2.1/OIDC with RBAC, web dashboard with Prometheus metrics, payload normalization against encoding bypasses, semantic shell AST analysis, mTLS zero-trust networking, circuit breakers, and a formal STRIDE threat model. 168 tests across 16 suites. Install: npm install -g @mcp-guardian/server
Runtime governance for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.
