[Bug]: 403 Authorization Error while connecting through AI foundry

### What happened?

I created a dab-config.json for sql-mcp-server, with **development** environment and authentication as **unauthenticated** and permission in entity as **anonymous**.

Hosted this setup to azure container apps(mainly followed below steps)
[https://learn.microsoft.com/en-us/azure/data-api-builder/mcp/quickstart-azure-container-apps](url)

Tried this mcp server via VS code github copilot, it's perfectly working by calling tools and fetching relevent response by connecting database instance.

But when i tried same setup with AI foundry, with "unauthenticated" it's throwing 403 error.
