Generally Available: Azure Functions now supports MCP resource triggers

Developers building MCP servers on Azure Functions can expose tools but not resources. Now, Azure Functions supports MCP resource triggers, enabling developers to expose resources directly from an Azure Functions–hosted Model Context Protocol (MCP) server. Resources can include static or dynamic files, application metadata, and MCP App UI content such as HTML-based widgets rendered natively by MCP hosts. This capability is available in the Azure Functions MCP extension for Python, TypeScript, .NET, and Java.  

With MCP resource triggers, developers can now build and host MCP servers on Azure Functions that provide richer context, interactive experiences, and structured data alongside tools.
