Frequently Asked Questions
Which integration should I use - stdio or HTTP?
For Claude Desktop, use stdio (npx command) for best performance. For Cursor, VS Code extensions, or custom apps, use HTTP (just add URL). Both support all 7 tools.
What operators are available?
6 operators: Replace (fake data), Redact (remove), Hash (SHA-256/512/MD5), Encrypt (AES-256 with your key), Mask (partial hide), and Keep (exclude from anonymization).
Can I use my own encryption keys?
Yes! Load personal AES keys (16/24/32 chars) from your account or enter them manually. Encrypt with your key, decrypt later with the same key. Keys never leave your control.
What are entity groups?
Predefined collections: UNIVERSAL (common PII), FINANCIAL (banking), DACH (German-speaking), FRANCE, NORTH_AMERICA, etc. Saves time configuring which entities to detect.
What's the difference between redact and tokenize modes?
Redact mode permanently removes PII. Tokenize mode replaces with reversible tokens and returns a session_id. Use detokenize_text with the session_id to restore original values.
How do sessions work?
Tokenization creates sessions (24h or 30-day persistence). Use list_sessions to see active sessions, delete_session to remove them. Sessions store the mapping between tokens and original values.
