# Claude Desktop
> Connect Claude to Cala
Claude Desktop uses OAuth, so you don't need an API key.
In Claude Desktop, go to **Customize → Connectors → Add → Browse connectors**, search for Cala and click on **Connect to Claude**.
A **browser tab** will open for you to log in to your Cala account. After you **authorize**, return to Claude Desktop and open the Cala connector to confirm all tools are enabled. If not, enable them manually.
**Pair with the agent skill.** The MCP server gives your agent access to Cala's tools. The [agent skill](/integrations/agent-skill) gives it the knowledge to use them well. Install both for the full experience.
