Description

The Model Context Protocol (MCP) is a way for apps to provide capabilities and context to a large language model. Azure Functions recently introduced an MCP extension as an early preview to enable conversations with the community. The extension makes it easy to build remote MCP servers that run at cloud scale.  

  

The preview now includes functions written in Java, enabling even more teams to create remote MCP servers with this model. The extension has also been updated with additional support for returning server instructions and metadata and defining required tool properties. Function authors can use these new options to customize how LLMs interacts with their tools. MCP tool trigger invocations are now also instrumented to provide insights into app behavior and assist in debugging MCP servers.
