Open saved test results

The standalone CLI includes a local viewer for runs saved in the default project database.

Create and open a run

From the project root used in Your first MCP test:

m3 test --ui -- tests/test_m3_starter.py

After pytest finishes, the CLI prints a tokenized loopback URL and opens the newly stored run. It remains running so the browser can load data. Press Ctrl+C when finished.

To open existing history without running tests:

m3 ui

Run m3 ui from the directory containing .m3/executions.sqlite. It currently uses that default path; a database selected with m3 test --results-db PATH cannot be supplied to m3 ui.

The server binds to 127.0.0.1 and requires the launch token. Treat the printed URL as a credential while the process is running. Do not expose the viewer through a public reverse proxy.
