## Features

- **List Chains**: Retrieve a list of all chain slugs from DeFiLlama, sorted by Total Value Locked (TVL) in descending order.
- **List Bridges**: Fetch all bridges, optionally including chain breakdowns, sorted by 24-hour volume.
- **Historical Volumes**: Get historical volume data for a bridge or chain, with dates formatted as `YYYY-MM-DD HH:MM:SS`.
- **Daily Token Stats**: Retrieve 24-hour token volume breakdowns, including token ID, symbol, decimals, deposit/withdrawal amounts, and USD values, sorted by deposit USD value.
- **Bridge Transactions**: Fetch transaction summaries for a specific bridge, with details like transaction hash, timestamp, and USD value.
- **Prompts**: Includes example prompts for analyzing bridge volumes and comparing bridges based on metrics like weekly volume.

## Prerequisites

- **Python**: Version 3.10 or higher.
- **uv**: Package and virtual environment manager for Python (recommended for dependency management).

## Installation

1. **Clone the Repository**:
   ```bash
   git clone https://github.com/kukapay/bridge-metrics-mcp.git

Key insights:
- The Polygon bridge shows consistent deposit and withdrawal activity over the past three days.
- Deposits are roughly double the withdrawals in USD value, indicating higher inflow than outflow.
- Transaction counts are stable, with deposits averaging 120 transactions per day.
