Secure LLM Proxy — MCP Server

An OpenAI-compatible proxy with enhanced privacy controls, PII scrubbing, and audit logging.

Features

• PII scrubbing — strips emails, phone numbers, SSNs, and credit card numbers before forwarding

• Audit logging — every request logged with hash of original content

• OpenAI-compatible — drop-in replacement, just change OPENAI_BASE_URL

• Model routing — supports GPT-4o, Claude, Gemini, and Llama via single endpoint

• Rate limit pooling — spreads load across multiple upstream keys

Privacy
