TL;DR: Cursor IDE sends code context to AI providers for completions and chat. Route through AI Privacy Gateway to ensure sensitive data in your codebase stays protected..
Integration = one config change. No SDK changes needed.
Why Add PII Masking to Cursor IDE?
Cursor IDE sends code context to AI providers for completions and chat. Route through AI Privacy Gateway to ensure sensitive data in your codebase stays protected.
How It Works
Your App + Cursor IDE
→
Privacy Gateway
(masks PII locally)
→
AI API
(receives clean data)
✓ PII masked before leaving your machine ✓ Zero code changes in your Cursor IDE integration
Benefits
✓
Protect proprietary code from being sent to AI servers
✓
Auto-mask secrets and tokens in code comments and strings
✓
Zero impact on Cursor's autocomplete speed
Setup: Connect Cursor IDE to AI Privacy Gateway
Configuration — Change One Line
# Cursor respects the OPENAI_BASE_URL environment variable
export OPENAI_BASE_URL="http://localhost:9999/v1"
# Or configure per-project .cursorrules
Step-by-Step Setup
- 1 Start the privacy gateway locally
- 2 Set OPENAI_BASE_URL to point to your gateway
- 3 Cursor completions and chat are now PII-masked

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