Azure Functions
An event-driven serverless compute service provided by Microsoft Azure that supports exposing function-based tools through MCP extensions.
Timeline (last 90 days)
In the reference architecture, the AI host connects via Azure API Management to MCP servers running on Container Apps or Functions; Microsoft Entra ID provides identity, API Management validates tokens, enforces rate limits and captures traces, the servers use managed identities to access backend APIs, and Azure Monitor and Application Insights record latency, failures and correlation identifiers.
Path B uses the Azure Functions MCP extension; a single Python function is decorated as an MCP tool, bindings can retrieve data such as Azure Blob Storage, and the MCP endpoint is hosted under the Functions runtime's webhook path, but the guide notes that the extension's current authentication and runtime support need to be evaluated and that preview limitations should be noted.
The Tailspin Toys website is fully prerendered with no backend server, so the browser cannot call the agent directly and should not hold Foundry credentials; the developer had Copilot build a small Azure Functions proxy to connect securely.
A prerendered website cannot call the agent directly, because a browser directly requesting the Foundry service would require issuing an API key or access token, which any user could view via F12 and steal; the Azure Functions proxy establishes a trusted channel on the server side, and credentials never leave the server side.
Parallel processing in engineering implementations typically relies on cloud function or task queue architectures, with common implementations including AWS Lambda, Azure Functions, Celery, and BullMQ.
