GitHub is managed through the Claude GitHub App rather than a credential; see Configure GitHub access.
Services marked (custom) aren’t in the Add a connector list. Add them with Custom connector following their guide.
Connect a service that has no guide
You can add any app that has an API as a custom connector or a custom MCP server, including services this page has no guide for. See Connect a custom service for the credential types and form fields.When a connector fails after setup
If Claude says it can’t reach a service you connected, start with the checks at the top of Troubleshoot Claude Tag setup. Open the channel’s page from the Channels tab under Claude’s access and confirm the connector is listed in its Claude’s access table. Then rerun the test in a new thread. Two entries on the troubleshooting page cover connector failures directly:- A connection works in one channel but not another: the connector, or the bundle that holds it, likely doesn’t apply to the failing channel
- I hit an authentication error and couldn’t finish this turn: Claude posts that message when its own request fails an authentication check. A connected service’s failing credential surfaces as a tool error inside Claude’s reply instead
