# Plugin, channel, and MCP problems

Diagnose the exact connection type—Plugin, Channel, or MCP Server—and reconnect only the layer that failed.

- Open the matching Settings section and read its current status and latest error.

- For OAuth plugins, confirm the correct provider account and scopes; for credential plugins, replace only changed secret fields.

- For Channels, verify destination mapping, webhook or mail settings, and the assigned agent or crew.

- For MCP Server, confirm the server address, transport, and tool discovery.

- Run one read-only capability before testing replies, publishing, or writes.




Saved secrets remain masked; a blank secret field during edit can mean “keep the existing value.” Disconnecting Foxora may not revoke the provider grant, so use the provider’s security page when full revocation is required.




**Expected result:** the intended capability appears and one safe call succeeds through the selected connection.
