One asset library for Models, MCPs, and Skills across every AI coding Agent.
Models, MCPs, Skills, and an Agent picker — in one desktop workspace.
Create a Provider once, add Models, and choose which compatible Agents use them. Account portals and protocol paths stay visible and editable.
Models & Providers →Download or import one central copy. Browse by source, read three-line descriptions, and open consumers through their Agent icons.
Manage Skills →Add, paste, import, or subscribe to MCPs. Assign from the central library while preserving each Agent’s unrelated settings.
Desktop guide →Batch status reads, inspect local traces, and review a plan before committing it in the original process. Desktop and CLI share the same assets and safety rules.
