01 · Install Lune Research

before you install - you'll need

LUNE_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add retrogradelabs-lune-mcp-server --transport http https://mcp.luneresearch.com

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "retrogradelabs-lune-mcp-server": {
      "url": "https://mcp.luneresearch.com"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to mcp.luneresearch.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

npm package @retrograde-labs/lune-mcp-server - the @retrograde-labs scope differs from the repo owner (retrogradelabs); confirm it's the project's official package

registry vendor namespace com.luneresearch - domain-verified with the official MCP registry
