Cursor

Connect Moonlit to Cursor through its MCP configuration file, for all projects or one.

Sign in: Moonlit account
Where: ~/.cursor/mcp.json, or .cursor/mcp.json in a project
Help: Cursor MCP documentation

Before you start

A Moonlit account. Sign in at app.moonlit.ai with your email and the one-time code it sends you, or with Google or Microsoft. Organizations can use single sign-on. Signing in creates the account if you do not have one.

The server URL:

https://mcp.moonlit.ai/mcp

Add the server

Add the server to ~/.cursor/mcp.json for all projects, or to .cursor/mcp.json at the root of one project:

{
  "mcpServers": {
    "moonlit": {
      "url": "https://mcp.moonlit.ai/mcp"
    }
  }
}

Cursor detects that the server needs a sign-in and shows a connection prompt for Moonlit. Follow it, sign in with your Moonlit account and click Allow.

Check it works

Open Customize in the sidebar and switch Moonlit on; its nine tools appear under available tools. In a chat in agent mode, ask:

Prompt

Find the official text of Article 6 of the EU AI Act.

A good answer cites CELEX 32024R1689, links to the official publication, and quotes the article.

Use an MCP key instead

For a configuration shared with your team, or a machine that cannot open a browser, an organization MCP key replaces the sign-in. Keys come from Organizations; keep them in an environment variable, never in the file itself.

{
  "mcpServers": {
    "moonlit": {
      "url": "https://mcp.moonlit.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${MOONLIT_MCP_KEY}"
      }
    }
  }
}

If something fails

Check that the URL ends in /mcp.
Remove the server entry, add it again, and sign in once more.
Ask for your Moonlit account status. The check is free and shows your remaining calls.
Cursor shows an MCP error in the chat: open the Output panel (Cmd+Shift+U), choose MCP Logs, and read the last lines for the Moonlit server.
