The MCP Server includes 12 guided prompts for common workflows, including solving, uploading, diagnostics, and model management. It also includes two resources: a live model catalog and a browsable example library reference.

| Command | Description |
|---|---|
| RASON: Set Auth Token | Set the bearer token for RASON API authentication. |
| RASON: Clear Auth Token | Remove the stored authentication token. |
| RASON: Open Settings | Open RASON extension settings. |
