Vibe Coding Safety: Prevent PII Leaks in AI-Generated Code
Cursor, Windsurf, and Claude Desktop ship production code at speed — but without PII guardrails. Anonymize sensitive data before it reaches your AI IDE and strip it from generated code automatically.
Why Vibe Coding Creates PII Risk
Vibe coding accelerates development — but AI IDEs like Cursor and Windsurf ingest your entire codebase context, including any real data used in tests, fixtures, or prompts. PII slips into model context, training fine-tunes, logs, and generated output silently.
Documented risks in AI-assisted development:
- CVE-2026-22708 (Cursor IDE): Credential and PII data in open files transmitted to model context without filtering. CVSS 8.1.
- LangChain CVE-2026-22708: CVSS 9.3 — prompt injection via RAG documents injects PII into unintended model outputs and logs.
- 8,000+ exposed MCP servers: Public MCP server scans reveal thousands processing raw PII without sanitization, violating GDPR and HIPAA.
Four Ways to Protect Your Vibe Coding Workflow
Choose the integration that fits your stack — or combine them for full-stack PII coverage.
MCP Server
Anonymize prompts transparently in Claude Desktop, Cursor, and any MCP-compatible IDE. PII is replaced before reaching the model; responses are de-anonymized automatically.
Learn moreREST API
Integrate PII anonymization directly into your CI/CD pipeline, test fixture generators, or code review bots via a single API call.
Learn moreChrome Extension
Protect browser-based AI IDEs and code assistants. Anonymizes text before it is sent from the browser — zero configuration required.
Learn moreDesktop App
Batch-process code files, test fixtures, and datasets locally before sharing with AI tools. Works offline with zero data leaving your machine.
Learn moreBuilt for Developer Workflows
Native IDE Integration
MCP Server connects directly to Cursor, Windsurf, Claude Desktop, and VS Code. No middleware, no proxies — just transparent PII anonymization in your existing workflow.
285+ Entity Types
Detect names, emails, API keys, credentials, SSNs, IBANs, and 285+ other PII types across 48 languages — including code-embedded secrets and hardcoded test data.
Reversible Anonymization
Replace PII with consistent placeholders (e.g. [PERSON_1], [EMAIL_1]) so AI-generated code stays functional. De-anonymize the output in one step to restore real values.
Zero-Knowledge Architecture
Your encryption keys never leave your device. anonym.legal cannot read your original data. CSPRNG-backed key generation with AES-256-GCM encryption.
GDPR & HIPAA Compliant
EU data residency. Anonymization meets GDPR Article 4(1) definition. Audit-ready reports for DPA inquiries and HIPAA compliance documentation.
Audit Logs
Every anonymization event is logged — entity types detected, timestamps, and session IDs — for compliance audits and incident response.
Set Up in Under 5 Minutes
Create a free account
Sign up at anonym.legal — free tier includes 200 tokens/month, all 285+ entity types, and full MCP Server access on the Pro plan.
Add the MCP Server to your IDE
Add the anonym-legal MCP Server config to your claude_desktop_config.json or Cursor settings. One JSON block — no binary installation.
Anonymize before every AI prompt
The MCP Server intercepts prompts containing PII and replaces entities with consistent placeholders before the model sees them. Fully transparent.
De-anonymize AI output
Paste the AI-generated code into the de-anonymize endpoint (or Chrome Extension) to restore original values. Your real data never touched the model.
