How to connect Truffle to Cursor with MCP

Cursor speaks MCP, so you can reach Truffle from inside your editor — handy for questions that span more than the file you're looking at ("does this API already exist?", "what calls this function across the repo?").

1. Create a token

In your Truffle dashboard, generate a personal access token (trfl_…) and note the MCP server URL shown there.

2. Add Truffle to Cursor's MCP config

Add a server to .cursor/mcp.json in your project (or Cursor's global MCP settings):

{
  "mcpServers": {
    "truffle": {
      "url": "https://asktruffle.com/mcp",
      "headers": { "Authorization": "Bearer trfl_your_token_here" }
    }
  }
}

Reload Cursor; Truffle shows up under its MCP tools.

3. Use it while you code

Ask Cursor's assistant a question about your connected sources and it'll call Truffle to answer — read-only, with sources. New to the protocol? Start with What is MCP?
