Claude Desktop

claude:// opens the desktop app: a new chat, an existing conversation, or a coding session.

The scheme is split by surface. Chat links carry a claude.ai host — claude://claude.ai/new — while the agent surfaces do not: claude://code/new and claude://cowork/new. The host is part of the path here, not a domain, and getting it wrong is the easiest way to write a link that goes nowhere.

Folders are always untrusted. A link that names a working directory raises a confirmation dialog every time, no matter how many times you have trusted that folder before. That is deliberate, and it means a link cannot quietly point an agent at your filesystem.

Encode every value.
