Lucairn SDKs
Official client libraries for Lucairn — an EU-based privacy-preserving AI gateway. Lucairn sits between your application (or AI agent) and the upstream LLM provider you choose, removes personal data from prompts before the model ever sees them, and returns a signed Lucairn Certificate proving what was redacted, when, and by which sanitizer layer.
This monorepo hosts four packages at parity:
@lucairn/mcp-server— Model Context Protocol server (one-linenpxinstall for Claude Desktop, Cursor, Cline, Continue, …)@lucairn/sdk— TypeScript / Node SDKlucairn— Python SDKgithub.com/declade/lucairn-sdks/go— Go SDK
Quick start (MCP)
For most agent use cases, the fastest path is the MCP server. No build step, no install — npx runs it on demand:
npx -y @lucairn/mcp-serverAdd it to your MCP client config (Claude Desktop's claude_desktop_config.json, Cursor's mcp.json, Cline's cline_mcp_settings.json, Continue, etc.):
