Describe the issue
When creating a custom MCP connector in Claude Enterprise (web and desktop app), the OAuth Client ID and Client Secret fields under Advanced Settings do not persist after saving.
Issue details
Steps to reproduce:
Go to Organization Settings → Connectors
Click + Add → enter connector name and MCP server URL
Expand Advanced Settings
Enter OAuth Client ID and Client Secret
Click Add
Go back to the connector → three dots → See details → expand Advanced Settings
Expected result: Client ID and Secret should be saved and visible (Secret masked)
Actual result: Both fields are blank — showing only the placeholder text "OAuth Client ID (optional)" and "OAuth Client Secret (optional)"
Impact: Without saved OAuth credentials, the connector never presents a Connect button to users, making it impossible to complete the OAuth Authorization Code flow. The connector is effectively non-functional for any MCP server requiring OAuth authentication.
Environment:
Claude Enterprise (web)
Claude Desktop app
Both exhibit the same behavior
Connector type: Custom MCP
OAuth flow required: Authorization Code
Additional context: This connector is pointing to an Oracle Integration Cloud (OIC) MCP Server that requires OAuth. The IDCS OAuth application is fully configured with Authorization Code grant type, redirect URL (https://claude.ai/oauth/callback), and bypass consent enabled. All OAuth settings on the server side are correct — the credential save issue appears to be entirely on the Claude side.
Expected behavior
The connection is created with the OAuth credentials, and a connect button made available.
