Alchemy MCP Server

A Model Context Protocol (MCP) server that enables AI agents to interact with Alchemy's blockchain APIs in a structured way. This allows agents to query blockchain data directly without writing any code.

General Usage

This MCP server creates a bridge between AI agents and Alchemy's blockchain APIs, allowing agents to:

• Query token prices and price history
• Get NFT ownership information
• View transaction history
• Check token balances across multiple blockchain networks
• Retrieve asset transfers
• And more!

Quick Setup

To quickly set up the MCP server, use the following configuration in your MCP config file (typically in Claude Desktop or Cursor settings):

{
  "mcpServers": {
    "alchemy": {
      "command": "npx",
      "args": [
        "-y",
        "@alchemy/mcp-server"
      ],
      "env": {
        "ALCHEMY_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

This configuration allows you to use the server without manually cloning the repository.
