README Excerpt

Stdio proxy that intercepts MCP `tools/call` JSON-RPC messages and runs them through a multi-layer security pipeline. Returns Allow / Block / Redact verdicts. Sits between an MCP agent and tool server, inspects every `tools/call` request, and makes a security decision before anything reaches the downstream server. No code changes required on either side.
