### 2026.08.29.r027
|
||||
- Stellt bei aktivierter Toolbox zwei echte MCP-Werkzeuge bereit: `unraid_toolbox_status` und `unraid_toolbox_exec`.
|
||||
- Agenten erkennen und verwenden Medienwerkzeuge direkt im dynamisch gelabelten Container, ohne lokales Docker oder Umwege über die Host-Shell.
|
||||
- Toolbox-Werkzeuge verschwinden automatisch aus `tools/list`, wenn der GUI-Schalter aus ist oder kein gelabelter Container existiert.
|
||||
|
||||
### 2026.08.29.r026
|
||||
- Erkennt optionale Agent-Werkzeugcontainer dynamisch über `mike.ai.role=toolbox` statt über einen fest eingebauten Namen.
|
||||
- Die WebGUI bietet den Toolbox-Schalter nur bei vorhandenem Label an und zeigt andernfalls eine konkrete Einrichtungsanleitung.
