### Description (declared)

# Stateless MCP 
 
A **stateless**, **multi-worker compatible** JSON-RPC 2.0 server with streaming support for MCP (Model Context Protocol). This library provides a drop-in replacement for FastMCP with true stateless architecture. 
 
## Key Features 
 
- **Stateless Architecture**: No session state, works with multiple workers 
- **JSON-RPC 2.0**: Full compliance with JSON-RPC 2.0 specification 
- **In-Band Streaming**: Streaming responses over HTTP without external infrastructure 
- **Multi-Worker Safe**: Deploy with multiple Uvicorn workers 
- **Simple API**: Decorator-based tool registration 
- **No External Dependencies**: No Redis, no message queues 
- **Autogen Compatible**: Works seamlessly with Autogen agents 
 
## Version 2.0 Features (New!) 
 
Version 2.0 adds production-ready observability, security, and operational features: 
 
### Observability & Monitoring 
- **Structured Logging**: JSON and console logging with request ID tracking and sensitive data masking 
- **Prometheus Metrics**: Request counters, duration histograms, streaming metrics, and active request gauges 
- **Enhanced Health Checks**: Kubernetes-compatible liveness, readiness, and startup probes 
 
### Security 
- **API Key Authentication**: Header-based authentication with multi-key support 
- **Rate Limiting**: Sliding window rate limiter with per-client tracking 
- **Permission System**: Role-based and permission-based access control 
 
### Operational 
- **Request Tracing**: Automatic request ID generation and tracking across logs 
- **Metrics Export**: `/metrics` endpoint for Prometheus scraping 
- **Tool Introspection**: Enhanced `/tools` and `/tools/{name}` endpoints for discovery 
- **Better Error Handling**: Contextual error messages with proper JSON-RPC error codes 
 
All v2 features are **opt-in** and **backward compatible** with v1.
