# Socket API
|
|
|
|
cmux exposes a Unix socket for programmatic control, enabling automation and integration with tools like Claude Code.
|
|
|
|
## Socket Location
|
|
|
|
| Build | Socket Path |
|
|
|-------|-------------|
|
|
| Release | `/tmp/cmux.sock` |
|
|
| Debug | `/tmp/cmux-debug.sock` |
|
|
|
|
You can override the path with the `CMUX_SOCKET_PATH` environment variable.
|
|
|
|
## Access Modes
|
|
|
|
cmux has three access modes, configurable in Settings:
|
|
|
|
| Mode | Description |
|
|
|------|-------------|
|
|
| **Off** | Socket disabled |
|
|
| **Notifications only** | Only notification commands allowed |
|
|
| **Full control** | All commands enabled |
|
|
|
|
<Callout type="warn">
|
|
On shared machines, use "Notifications only" mode to prevent other users from controlling your terminals.
|
|
</Callout>
|
|
|
|
## Protocol
|
|
|
|
Commands are sent as newline-terminated JSON:
|
|
|
|
```json
|
|
{"command": "command-name", "arg1": "value1"}
|
|
```
|
|
|
|
Responses are newline-terminated JSON:
|
|
|
|
```json
|
|
{"success": true, "data": {...}}
|
|
{"success": false, "error": "Error message"}
|
|
```
|
|
