### Description (declared)

# Azure Functions MCP STDIO Adapter

A Python extension for Azure Functions that acts as an adapter between MCP (Model Context Protocol) servers running on STDIO and HTTP clients. This adapter surfaces STDIO-based MCP servers as streamable HTTP endpoints without modifying the underlying MCP server behavior.

## Overview

The Azure Functions MCP STDIO Adapter enables seamless integration between:

- **Input**: Python MCP servers that communicate via STDIO (JSON-RPC over stdin/stdout with Content-Length framing)
- **Output**: Azure Functions HTTP endpoints that expose streamable HTTP responses
- **Transport**: Maintains protocol parity without modifying customer MCP servers

### Data Flow Diagram

```
Client ⇄ HTTP Stream ⇄ Azure Function Adapter ⇄ STDIO ⇄ MCP Server
      │                     │                  │           │
      │                     │                  │           └─ Customer's MCP Server
      │                     │                  └─ JSON-RPC over STDIO
      │                     └─ Process Management & Forwarding
      └─ Streamable HTTP Responses
```

## Features

- **Multi-format Configuration Support**: Supports various JSON configuration formats
- **Process Lifecycle Management**: Automatic start, monitor, and graceful shutdown of MCP servers
- **Streaming HTTP Integration**: Uses MCP SDK's StreamableHTTPSessionManager for real-time communication  
- **UVX Integration**: Supports `uvx` (uv tool run) for running MCP servers without global installation
- **Error Recovery**: Handles MCP server crashes and reconnection scenarios
- **Environment Variable Support**: Passes through environment variables to MCP servers
- **Well-known Configuration Files**: Supports loading from standard file locations

## Session Isolation & Multi-Tenancy

The Azure Functions MCP STDIO Adapter provides **best-effort session isolation** for multi-tenant scenarios while maintaining optimal resource utilization.
