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. The Desktop App reads files on your device; detection runs on the EU-hosted API.
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.
273 Entity Types
Detect names, emails, API keys, credentials, SSNs, IBANs, and 273 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.
Persediaan setiap IDE, bukan automatik
Integrasi MCP Server mempunyai had sebenar yang wajar dinyatakan di awal: ia memerlukan persediaan pembangun bagi setiap IDE dalam Cursor, Windsurf atau Claude Desktop, bukan tanpa konfigurasi atau serasi dengan semua IDE secara automatik. Mana-mana kandungan codebase yang sudah dimasukkan ke dalam konteks IDE AI sebelum pelayan MCP dikonfigurasikan tidak dilindungi secara retroaktif.
Set Up in Under 5 Minutes
Create a free account
Daftar di anonym.legal — peringkat percuma termasuk 200 token/bulan dan jenis entiti teras; entiti khusus negara mulai Basic. Akses MCP Server memerlukan pelan Pro.
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.
