DeAI API MCP Server

A Model Context Protocol (MCP) server that provides tools to interact with the DeAI API for token analysis, holder tracking, and wallet portfolio analytics on Ethereum.

Features

The MCP server exposes the following tools for analytics (Currently supports ETH):

• get_token_info - Get detailed token information including name, symbol, decimals, logo, and token tax
• get_top_holders - Analyze the holders of any token with their balances and percentages
• get_token_holder_balance_changes - Track balance changes for token holders over the last 7 days
• get_portfolio - Get comprehensive portfolio data for any wallet including total value, changes, and token holdings

Troubleshooting

Common Issues

1. "API_KEY environment variable is required"

export API_KEY="your_api_key"

2. "Network error: Unable to reach DeAI API"

• Check your internet connection
• Verify the API endpoint is accessible
• Ensure API key is valid

3. "API Error (401): Unauthorized"

• Verify your API key is correct
• Check if your API key has expired
• Ensure sufficient credits remain

4. Claude Desktop not finding the server

• Use absolute paths in configuration
• Ensure the working directory is set correctly
• Restart Claude Desktop after config changes
