TL;DR: Claude Code is Anthropic's agentic coding tool that reads your entire codebase. AI Privacy Gateway masks sensitive patterns in your code before they reach Anthropic's servers..
Integration = one config change. No SDK changes needed.
Why Add PII Masking to Claude Code?
Claude Code is Anthropic's agentic coding tool that reads your entire codebase. AI Privacy Gateway masks sensitive patterns in your code before they reach Anthropic's servers.
How It Works
Your App + Claude Code
→
Privacy Gateway
(masks PII locally)
→
AI API
(receives clean data)
✓ PII masked before leaving your machine ✓ Zero code changes in your Claude Code integration
Benefits
✓
Protect API keys, tokens, and secrets embedded in code
✓
Mask PII in test fixtures and database seeds
✓
Keep proprietary algorithms confidential from AI analysis
Setup: Connect Claude Code to AI Privacy Gateway
Configuration — Change One Line
# Set environment variable to route through gateway
export ANTHROPIC_BASE_URL="http://localhost:9999/v1"
# Or configure in Claude Code settings
claude config set ANTHROPIC_BASE_URL "http://localhost:9999/v1"
Step-by-Step Setup
- 1 Deploy gateway: docker run -d -p 9999:9999 ghcr.io/gunxueqiu6/ai-privacy-gateway:lite
- 2 Set ANTHROPIC_BASE_URL=http://localhost:9999/v1
- 3 Run Claude Code normally — PII and secrets in code are auto-masked

Frequently Asked Questions
Does this work with the latest version of Claude Code?
Yes. AI Privacy Gateway works at the HTTP layer as a transparent proxy. It is compatible with any version of Claude Code that makes HTTP API calls.
Will this affect my Claude Code performance?
The gateway adds less than 1ms per request. The PII detection engine is written in Rust for maximum throughput, so your Claude Code application performance will not be noticeably affected.
Can I use this with multiple AI providers through Claude Code?
Yes. Route all your AI API calls through the same gateway. It works transparently with any OpenAI-compatible API — just change the base URL.
