Pseudonymizes PII before your LLM and returns a cryptographically signed receipt per response.

Install

claude mcp add lucairn-mcp-server -- npx -y @lucairn/[email protected]

Requires: LUCAIRN_API_KEY, ANTHROPIC_API_KEY, OPENAI_API_KEY, LUCAIRN_BASE_URL, LUCAIRN_TRANSPORT

Our take

An EU privacy gateway for LLM calls: the chat_via_lucairn tool routes prompts through gateway.lucairn.eu, which strips PII (Presidio NER plus entity matching) before the text reaches Anthropic or OpenAI, and returns a cryptographically signed redaction certificate. The monorepo is substantive — TS, Python, and Go SDKs with tests — and the docs are unusually candid. Two things to weigh: every prompt (and on the free BYOK tier, your upstream Anthropic/OpenAI key, forwarded per-request) transits their gateway, and the free tier returns placeholder tokens like [PERSON_1] verbatim rather than re-linked text, which limits it to testing the redaction surface.
