Connect Claude Code

Claude Code connects to Trace natively over HTTP. Add the server once, then complete the OAuth sign-in from inside a session.

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 the server:

   claude mcp add --transport http trace https://mcp.tracedata.ai/mcp

2. Start (or resume) a Claude Code session and run:

   /mcp

   This lists your MCP servers and triggers the browser sign-in for any that need authentication. You can also run claude mcp login trace directly.

3. Log in to Trace and approve access. Tokens are stored in your OS keychain, so you only sign in once per machine.

Tip

HTTP is the recommended transport for remote MCP servers. SSE is deprecated — use --transport http as shown above.

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.
