Configure Claude Desktop

Add the following configuration to your Claude Desktop config file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "anchain-data": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/anchain-data-mcp",
        "mcp_server.py",
        "--ANCHAIN_APIKEY",
        "your_api_key_here"
      ]
    }
  }
}

Replace /path/to/anchain-data-mcp with the actual path to your project folder and your_api_key_here with your AnChain API key.

Configure Cursor

Add the following to your Cursor MCP settings file mcp.json:

{
  "mcpServers": {
    "anchain-data": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/anchain-data-mcp",
        "mcp_server.py",
        "--ANCHAIN_APIKEY",
        "your_api_key_here"
      ]
    }
  }
}

Configure Other MCP-Compatible Platforms

For other AI platforms that support the Model Context Protocol (such as Zed, Sourcegraph Cody, or custom integrations), add a similar configuration to their MCP settings file:

{
  "mcpServers": {
    "anchain-data": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/anchain-data-mcp",
        "mcp_server.py",
        "--ANCHAIN_APIKEY",
        "your_api_key_here"
      ]
    }
  }
}

Consult your platform’s documentation for the exact location of the MCP configuration file.

Usage

Once configured, the AnChain Data MCP server will be available in Claude Desktop. You can ask Claude to:

• Assess blockchain address risks
• Screen addresses against sanctions lists
• Analyze transaction patterns
• Investigate smart contracts
• Access blockchain intelligence and news

The MCP server exposes all AnChain.AI Data API capabilities as tools that Claude can use automatically based on your requests.
