### Description (declared)

# listo-mcp-observability

Lightweight telemetry SDK for Python MCP servers. Captures MCP tool invocations, HTTP requests, business events, and UI interactions with built-in payload sanitization.

Python port of [@listo-labs-ltd/mcp-observability](https://github.com/Listo-Labs-Ltd/mcp-observability) (TypeScript).

## Features

- **Easy setup** — 3 lines with `create_mcp_observability_easy()`
- **Local dashboard** — Real-time metrics at `/telemetry/dashboard`
- **Centralized analytics** — Send to Listo in production
- **MCP tool tracking** — Decorator-based (`@obs.track_tool()`) or programmatic wrapping
- **Payload sanitization** — Redacts password, token, apiKey, secret, authorization, userid, email, phone, and more
- **Sampling** — Configurable rates with guaranteed error/session capture
- **Zero runtime dependencies** — Core uses only Python stdlib
- **Event categories** — Classify business and UI events as conversion, engagement, impression, navigation, or system
- **Batch ingestion** — `POST /telemetry/events` for efficient multi-event ingestion
- **Platform detection** — Identify which AI platform (Claude, ChatGPT, etc.) initiated each session and tool call
- **Sink composition** — `combine_sinks()` to route events to multiple destinations

## Installation

```bash
# From PyPI
pip install listo-mcp-observability

# With uv
uv add listo-mcp-observability

# With optional MCP SDK support
pip install "listo-mcp-observability[mcp]"

# With optional Starlette dashboard support
pip install "listo-mcp-observability[starlette]"
```

## Quick Start

```python
from mcp.server.fastmcp import FastMCP
from mcp_observability import create_mcp_observability_easy

mcp = FastMCP("my-server")
obs = create_mcp_observability_easy(service_name="my-server")

@mcp.tool()
@obs.track_tool("search_hotels")
async def search_hotels(query: str) -> str:
    return f"Results for {query}"
```
