Overview
The whale-tracker-mcp server is a Python-based implementation of the Model Context Protocol (MCP) that integrates with the Whale Alert API. It enables real-time tracking and analysis of large cryptocurrency transactions ("whale" movements) by exposing tools, resources, and prompts to MCP-compatible clients like Claude Desktop.
This server is designed for cryptocurrency enthusiasts, developers, and analysts who want to monitor whale activity directly within their LLM-powered workflows.
Features
- **Tools**:
- get_recent_transactions: Fetch recent whale transactions with optional filters for blockchain, minimum value, and limit.
- get_transaction_details: Retrieve detailed information about a specific transaction by its ID.
- **Resources**:
- whale://transactions/{blockchain}: Expose recent transactions for a specified blockchain as contextual data.
- **Prompts**:
- query_whale_activity: A reusable template for analyzing whale transaction patterns, optionally filtered by blockchain.
- **Asynchronous API Calls**: Uses httpx for efficient, non-blocking requests to the Whale Alert API.
- **Environment Variable Support**: Securely manage your API key via a .env file.
Prerequisites
- **Python**: Version 3.10 or higher.
- **Whale Alert API Key**: Sign up at whale-alert.io to obtain an API key.
- **MCP Client**: Compatible with MCP clients like Claude Desktop or the MCP Inspector.

3. Set up your API key: Create a .env file in the project root and add your Whale Alert API key:
Usage
Running in Development Mode
Test the server locally with the MCP Inspector:
This opens a web interface where you can explore the server's tools, resources, and prompts.
Integrating with Claude Desktop
Install the server into Claude Desktop for seamless integration:
- --name "WhaleTracker": Sets a custom name for the server in Claude Desktop.
- -f .env: Loads the API key from the .env file.
Restart Claude Desktop after installation. Look for the hammer icon in the input box to confirm the server is loaded, then try commands like:
- "Show me recent whale transactions on Bitcoin."
- "Get details for transaction ID 123456789."
- "Analyze whale activity on Ethereum."
Direct Execution
Run the server standalone for custom deployments:
Or use the MCP CLI:
