### Description (declared)

# MCP Observability SDK for Python

Open, vendor-agnostic observability SDK for Model Context Protocol (MCP) applications. No vendor lock-in, plug-and-play integration, and extensible for rate limiting, tool filtering, auth, and traceability.

## Installation

```bash
pip install mcp-hack
```

## Quick Start

### 1. Get an API Key

1. Visit [https://etalesystems.com](https://etalesystems.com)
2. Sign in with your Google account
3. Create a new API key from the dashboard
4. Set your API key as an environment variable:

```bash
export MCP_API_KEY="your_api_key_here"
```

### 2. Use in Your Code

```python
import os
from mcp_observability import MCPObservability

# Initialize observability
obs = MCPObservability(
    api_url="https://etalesystems.com/api",  # Production backend URL
    api_key=os.getenv('MCP_API_KEY')  # Your API key from etalesystems.com
)

# Add observability to your MCP tools
@mcp.tool()
@obs.tool_observer("add_numbers")
def add(a: int, b: int) -> int:
    """Add two numbers"""
    return a + b

# Get metrics
metrics = obs.get_metrics()
print(f"Total calls: {metrics['summary']['total_calls']}")
```

## Features

- 🔍 **Automatic Tool Tracing**: Monitor all MCP tool calls with zero configuration
- 📊 **Rich Metrics**: Execution time, success rates, error tracking
- 🚀 **Non-blocking**: Async trace submission doesn't slow down your tools
- 🔒 **Secure**: API key authentication with environment variable support
- 📈 **Dashboard Integration**: Real-time visualization of your MCP tools
