Connect Claude and Claude Desktop

Claude can connect only if your organization has Claude's request headers beta. Without it, Claude connects only through OAuth sign-in, and Harmony's OAuth support is still in progress.

1. In Claude, add a custom connector.
2. Enter https://api.harmony.ai/api/mcp as the server URL.
3. Under Authentication, choose No sign-in.
4. Under Request headers, add an authorization header with the value Bearer harmony_pk_.... Keep the space after Bearer.
5. Start a chat and ask: "List my Harmony workflows."

On Team and Enterprise plans, an Owner adds the connector for the whole organization, so everyone in it uses the same key. If your Account is in the EU, use https://api.eu.harmony.ai/api/mcp.
