Connect Cursor

Cursor connects to Trace natively. Add the server to your MCP config, then complete the OAuth sign-in when Cursor prompts you.

Before you start

You need a Trace account. Connecting uses OAuth — you’ll sign in to Trace in your browser; there’s no API key to paste. Your Trace email must be verified. See Authentication for the full access model.

Steps

1. Add Trace to your MCP config. Use ~/.cursor/mcp.json for all projects, or a project-local .cursor/mcp.json to scope it to one workspace:

   .cursor/mcp.json

   { "mcpServers": { "trace": { "url": "https://mcp.tracedata.ai/mcp" } } }

2. Reopen Cursor’s MCP settings (or restart Cursor). Trace appears in the server list.

3. When prompted, complete the OAuth sign-in in your browser. Log in to Trace and approve access.

Tip

Cursor also supports a one-click cursor:// deeplink for adding MCP servers, if you’d rather not edit JSON by hand.

Note

Connecting uses the standard MCP OAuth discovery flow. The client calls the Trace server, gets a 401 pointing at the OAuth metadata, registers itself automatically (Dynamic Client Registration), and then runs the browser sign-in. You don’t configure any of this by hand. Cursor’s OAuth callback is https://www.cursor.com/agents/mcp/oauth/callback.
