You are connected

Start with narrow requests:

  • ask what Zentrik already knows about a problem or idea
  • pull the relevant opportunity, evidence, or context record before you act

Troubleshooting

These items are about workflow and expectations in the product, not a broken OAuth client. If something contradicts what you see in your workspace, note your workspace name and the screen, then contact us.

Authenticate does not appear

Wait for discovery to finish, then reopen Codex if needed. The most common cause is a URL mismatch; it must be exactly /mcp on https://zentrik.ai.

Codex asks for a token

Do not use a workspace API key for MCP. Leave token fields empty and use the browser OAuth flow instead.

I chose the wrong workspace

Run the auth flow again and choose the correct workspace. Each MCP connection is bound to one workspace at a time.
