README Excerpt

A transparent proxy that sits between MCP clients (like Claude) and backend MCP servers, automatically detecting and masking PII with deterministic surrogates. When a tool returns results containing names, emails, SSNs, or other personal data, they're replaced with realistic fake values. When the client calls a tool using those fake values, the real data is restored before reaching the backend.
