Example output uses fixture accounts and hashes, captured with the CLI's output
formatters. Plain-text output is shown without terminal colors; your values and
relative expiry dates will differ.

With `--output json`:

<div className="docs-response">

```json
{
  "profile": "default",
  "apiOrigin": "https://api.namera.ai",
  "status": "connected",
  "scopes": ["mcp:read", "mcp:execute", "offline_access"]
}
```

</div>

## Options [#options]

### --profile [#--profile]

- **Type:** `string`
- **Default:** `default`

Choose the MCP connection name. This is separate from ordinary CLI profiles,
whose default is `personal`. Use the same name for `serve`, `login`, `status`,
and `logout`.

### --host [#--host]

- **Type:** absolute API URL
- **Default:** `https://api.namera.ai`

Choose the API origin for this MCP connection. The origin and profile together
identify its saved credentials. Use HTTPS, or a loopback HTTP origin for local
development. `NAMERA_API_URL` does not override this option on MCP commands.

The command also accepts [global options](https://namera.ai/docs/cli/reference/global-options):
`--output pretty|json`, `--quiet`, and `--help`.

This is separate from `namera login`. Approve only the session keys and MCP
permissions the agent needs. Credentials persist in the OS keyring. If the
browser cannot open, follow the printed URL. Imported signing keys must be
available to the OS user running the MCP process.

## Errors [#errors]

Failures exit nonzero and are written to stderr. With `--output json`, inspect
`error.code` and `error.nextStep`. See [Output and Errors](https://namera.ai/docs/cli/output-and-errors).
