Connect ChatGPT Desktop

You only need:

You do not need Developer mode, Node.js, or environment variables.

  1. Add the Celoxis MCP server
    1. Open ChatGPT Desktop.
    2. Open Settings.
    3. Navigate to Integrations → Plugins.
    4. Open the MCPs tab.
    5. Click Add → Add MCP Server.

    The form title should be Connect to a Custom MCP.

    The form opens with Type set to STDIO. That is not the Celoxis path. Do not keep STDIO selected. Celoxis MCP is a remote HTTPS server.

  2. Configure the connection
    FieldValue
    NameCeloxis MCP
    TypeStreamable HTTP
    URLYour Celoxis MCP URL
    Header KeyAuthorization
    Header Value<access-token>

    Important:

    • Do not keep STDIO selected
    • Leave Bearer token env var empty
    • Leave Headers from environment variables empty
    • Ensure there is exactly one space after Bearer

    Click Save.

  3. Verify the connection
    1. Completely close ChatGPT Desktop.
    2. Reopen the application.
    3. Start a new conversation.
    4. Ask: Who am I in Celoxis?

    The returned user should match the owner of the access token. If it doesn't, you are probably using the wrong token.
