Motivation and Context
This PR adds native Model Context Protocol (MCP) tool endpoint support to the Azure Functions integration for the Agent
Framework. This enables agents to be exposed as MCP tools that can be invoked by MCP-compatible clients, in addition to
traditional HTTP endpoints.
Description
- Added enable_mcp_tool_endpoint parameter (app-level and per-agent)
- Implemented _setup_mcp_tool_trigger() method to register Azure Functions MCP tool triggers
- Implemented _handle_mcp_tool_invocation() method to process MCP tool requests
- Added agent_mcp_tool_flags dictionary to track per-agent MCP settings
- Updated health check endpoint to include mcp_tool_enabled field
- MCP tools accept query (required) and threadId (optional) parameters
- Handles both JSON string and pre-parsed dict contexts defensively
- Integrates with existing durable entity infrastructure for conversation state
