**Usage tracking and analytics for MCP servers.** Pure Python, zero required dependencies.

Track which tools get called, how often, and keep an audit trail - all in 3 lines of code.

## Installation

```bash
pip install mcpstat
```

With MCP SDK:
```bash
pip install "mcpstat[mcp]"
```

## Quick Start

```python
from mcp.server import Server
from mcpstat import MCPStat

app = Server("my-server")
stat = MCPStat("my-server")

@app.call_tool()
@stat.track  # ← One decorator does everything!
async def handle_tool(name: str, arguments: dict):
    # Your logic here - latency tracked automatically
    return await my_logic(arguments)
```

Then ask your AI assistant: *"Give me MCP usage stats"*

## Features

- **SQLite-backed** - Stats persist across restarts
- **Built-in MCP tools** - `get_tool_usage_stats`, `get_tool_catalog`
- **Tag system** - Categorize and filter tools
- **Token tracking** - Estimate or record actual token usage
- **Latency tracking** - Measure execution duration, identify slow tools
- **File logging** - Optional timestamped audit trail
- **Async-first** - Thread-safe via `asyncio.Lock`
