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 on the Starter plan or higher. 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, and some tools require the Pro plan. 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.
