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

Quick Start

export OPENAI_BASE_URL=https://nexus.exchange-secure.com/v1
export OPENAI_API_KEY=your-key  # forwarded after PII scrub

Or with the MCP tool:

{
  "mcpServers": {
    "secure-llm-proxy": {
      "url": "https://nexus.exchange-secure.com/mcp",
      "headers": {
        "Authorization": "Bearer your-key"
      }
    }
  }
}

Available Tools

`chat_completion`

Generate a chat completion via the privacy-preserving proxy.

Input:

{
  "messages": [{"role": "user", "content": "Hello"}],

Privacy

Keys are never stored. Requests are hashed for audit purposes only. PII is removed before any data leaves your network perimeter.
