Lucairn Privacy Gateway MCP Server 工具

Send a chat request through the Lucairn privacy gateway with cross-provider BYOK (Anthropic + OpenAI). PII is detected and replaced with placeholders before reaching the upstream LLM. The gateway picks the upstream provider based on the `model` parameter: `claude-*` / `anthropic-*` use ANTHROPIC_API_KEY; `gpt-*` / `openai-*` / `o1-*` / `o3-*` / `o4-*` use OPENAI_API_KEY. Wire format follows the Anthropic Messages API. Developer-tier responses contain raw placeholders; Pro and Enterprise tiers can enable automatic re-linking back to the original values.

概览

What is Lucairn Privacy Gateway?

Lucairn Privacy Gateway is an EU-based privacy gateway for AI agents. It sits between an MCP-enabled client and upstream OpenAI or Anthropic models, pseudonymizes personally identifiable information (PII) before the model sees it, and returns a signed verification receipt for each request.

How to use Lucairn Privacy Gateway?

Run npx -y @lucairn/mcp-server to start the server. Configure your MCP client (e.g., claude_desktop_config.json) with the command and environment variables LUCAIRN_API_KEY, ANTHROPIC_API_KEY, and/or OPENAI_API_KEY. The server exposes one tool, chat_via_lucairn, which you call with a messages-style payload.

常见问题

How do I get an API key?

Create a free Developer account at https://lucairn.eu/account/signup.

What models are supported?

The gateway supports any OpenAI or Anthropic model available to your provider account. Model prefixes `claude-*`/`anthropic-*` route to Anthropic; `gpt-*`/`openai-*`/`o1-*`/`o3-*`/`o4-*` route to OpenAI.

PII is replaced with placeholders like `[PERSON_1]` before the request reaches the model. On the Developer tier, placeholders remain visible in responses; Pro and Enterprise tiers support relinking.

Is the Developer tier free?

Yes, the Developer tier includes 500 requests per month and does not require a credit card. You must provide your own OpenAI or Anthropic API key.

Where can I verify a receipt?

Use the verification tool at https://lucairn.eu/verify to check the signed receipt returned with each response.
