An MCP server implementation wrapping Ankr Advanced API.

## Overview

FastMCP is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that provides access to Ankr's Advanced API for blockchain data. It allows LLMs to interact with blockchain data across multiple chains including Ethereum, BSC, Polygon, Avalanche, and more.

## Features

- Complete wrapper for all Ankr Advanced API endpoints
- NFT API: Get NFT metadata, holders, transfers, and ownership information
- Query API: Access blockchain statistics, blocks, logs, and transaction data
- Token API: Get token balances, prices, holders, and transfer history
- Support for multiple blockchain networks

## Installation

```bash
# Clone the repository
git clone https://github.com/tumf/web3-mcp.git
cd web3-mcp

# Install with uv
uv pip install -e .
```

## Configuration

Set the following environment variables:

```bash
# Required
export ANKR_ENDPOINT="your_ankr_rpc_endpoint"

# Optional but recommended for authenticated requests
export ANKR_PRIVATE_KEY="your_private_key"
```

## Usage

### Running the server

```python
from web3_mcp.server import init_server

# Initialize MCP server
mcp = init_server(
    name="Ankr MCP",
    endpoint="your_ankr_endpoint",  # Optional, defaults to ANKR_ENDPOINT env var
    private_key="your_private_key"  # Optional, defaults to ANKR_PRIVATE_KEY env var
)

# Run server
mcp.run()
```

### Using with FastMCP CLI

```bash
# Set environment variables first
export ANKR_ENDPOINT="your_ankr_endpoint"
export ANKR_PRIVATE_KEY="your_private_key"

# Run the server
python -m web3_mcp
```
