Cursor IDE Integration

  1. Install Cursor IDE from cursor.sh

  2. Edit ~/.cursor/mcp.json (for macOS/Linux) or C:\Users\<Username>\.cursor\mcp.json (for Windows):

{
  "mcpServers": {
    "allthatnode-mcp": {
      "url": "https://mcp.allthatnode.com",
      "env": {
        "x-allthatnode-api-key": "YOUR_API_KEY"
      }
    }
  }
}
  1. Restart Cursor IDE

Claude Desktop Integration

  1. Install Claude Desktop Client

  2. Edit the configuration file:

    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: C:\Users\<Username>\AppData\Roaming\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "allthatnode-mcp": {
      "url": "https://mcp.allthatnode.com",
      "env": {
        "x-allthatnode-api-key": "YOUR_API_KEY"
      }
    }
  }
}
  1. Restart Claude Desktop Client

Available Tools

1. sendRpcRequest

Sends RPC requests to blockchain networks.

Parameters:

  • network: Target network (e.g., ethereum-mainnet, ethereum-sepolia)
  • method: RPC method name (e.g., eth_blockNumber, eth_getBalance)
  • params: RPC method parameters (array format)

Example:

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "sendRpcRequest",
    "arguments": {
      "network": "ethereum-mainnet",
      "method": "eth_blockNumber",
      "params": []
    }
  },
  "id": 1
}

2. showRPCEndpointList

Provides information about all supported networks.

Example:

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "showRPCEndpointList",
    "arguments": {}
  },
  "id": 2
}

Important Notes

API Key Management

  • Keep your API key secure
  • Use environment variables for API keys in production

Usage Examples

1. List Supported Networks

Question: How can I see all networks supported by AllThatNode MCP?

Answer: You can use the showRPCEndpointList tool to get the list.

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "showRPCEndpointList",
    "arguments": {}
  },
  "id": 1
}

Result: Currently supporting over 40 networks, including:

  • Ethereum (Mainnet, Sepolia, Holesky)
  • Layer 2 (Arbitrum, Optimism, Base)
  • Bitcoin (Mainnet, Testnet)
  • Polygon, BSC, Avalanche, and more

2. Check Vitalik's ETH Balance

Question: What is the ETH balance of Vitalik's address (0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045)?

Answer: You can check using the sendRpcRequest tool with the eth_getBalance method.

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "sendRpcRequest",
    "arguments": {
      "network": "ethereum-mainnet",
      "method": "eth_getBalance",
      "params": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045", "latest"]
    }
  },
  "id": 1
}

Result: The current balance is approximately 929.28 ETH (0xce0f57387983f205a Wei)

3. Get Latest Ethereum Block Number

Question: What is the current latest block number on Ethereum?

Answer: You can check using the sendRpcRequest tool with the eth_blockNumber method.

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "sendRpcRequest",
    "arguments": {
      "network": "ethereum-mainnet",
      "method": "eth_blockNumber",
      "params": []
    }
  },
  "id": 1
}

Result: The current latest block number is #22422862 (0x155b54e)
