Getting Started

npx @getmcp/cli add work.nacre/nacre

Requires Node.js 18+. Community-contributed server. Review source before installing.

Required Environment Variables

NACRE_SERVICE_KEY
Service-account key for STDIO mode. The server also needs the deployment's full environment (database and backend configuration) - see docs/mcp.md; the key alone is not enough to start it.

Configuration

Config file: ~/Library/Application Support/Claude/claude_desktop_config.json
