Alchemy MCP Server

The Alchemy MCP Server gives your AI tools direct access to blockchain data through the Model Context Protocol (MCP). Query token prices, NFT ownership, transaction history, and more as tool calls, with no code required.

Add this configuration to your MCP config file:

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

Get your API key at the Alchemy Dashboard.

The Alchemy MCP server currently only supports STDIO transport for local MCP client use. Remote connection via Streamable-HTTP transport is in development.

Add the configuration above to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Restart Claude Desktop after saving.

Add the configuration to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-level).

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

Add to .vscode/mcp.json in your project:

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