The docs reference this example with custom headers:

  mcpServers:
    - name: mcp-server-1  2 
      streamableHTTP:
        url: http://localhost:8080/mcp  3 
        timeout: 30
        sseReadTimeout: 10
        headers:
          - Authorization: Bearer <token>
          - Content-Type: application/json
          - Accept: application/json
        enableSSE: true

The issue is that in the latest OLS version headers are expected as objects rather than array, and header values must come from secrets.

Always    

    1. Try to add headers as the doc suggests, API will refuse to add them because it expects map of strings rather than array.
    2. If you add them as a map of strings but you simply put a value after the key:  controller will complain about not finding the secret.
