Lucairn Mcp Server

Overview

Lucairn Mcp Server is a Model Context Protocol (MCP) server: Pseudonymizes PII before your LLM and returns a cryptographically signed receipt per response. Because it speaks the Model Context Protocol, AI assistants can use Lucairn Mcp Server as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @lucairn/mcp-server speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need LUCAIRN_API_KEY. The current release is v1.2.9, published under the MIT license, with source at Declade/lucairn-sdks on GitHub.

On mcp.site, Lucairn Mcp Server sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
