How to Use the Nodereal MCP in Cursor

Q: Can Cursor and Nodereal help me debug failing EVM transactions?

They do exactly that. The agent calls debugtracetransaction on your failed hash. It reads the stack trace and highlights the exact line in your smart contract that triggered the failure.

Inject live EVM and Aptos chain data directly into your Cursor MCP workflow.

Cursor MCP Server Integration

`eth_get_block_by_number` and `aptos_get_blocks_by_height` feed live chain data straight into your editor. When you write indexing scripts, Cursor doesn't have to guess the JSON payload structure. It calls the tool, reads the actual block data, and writes the parsing logic based on reality. This changes how you write blockchain integrations. If you need to interact with a specific contract, your AI client uses `eth_call` to read its current state. The agent then generates the exact TypeScript interfaces required for your frontend.

Instant Transaction Simulation

`aptos_simulate_transaction` lets Cursor test your Move payloads before you commit them. You write the transaction builder function, and the agent simulates it against the live network. You see the gas estimates and state changes right in your terminal panel. On the EVM side, `eth_estimate_gas` ensures your hardcoded gas limits are accurate. When your transaction logic fails, Cursor uses `debug_trace_transaction` to pinpoint the exact line in your Solidity code that caused the revert.

Write Better Token Indexers

`nr_get_token_holders` and `nr_get_nft_holders` provide instant arrays of top holders for any contract. When you build a dashboard, Cursor pulls this live data to mock up your UI components. You get real wallet addresses instead of generic placeholder text. The agent also uses `nr_get_transaction_receipts_by_block_number` to write your block ingestion scripts. It sees exactly how the receipts are formatted and writes the database insertion code to match that exact schema.

Setup guide

Set up Nodereal MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Nodereal MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Nodereal transactions." If the MCP tools are loaded correctly, Cursor will call the Nodereal tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "nodereal-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about Nodereal MCP in Cursor

Create a .cursor/mcp.json file in your project root. Add the server command or remote URL, save the file, and enable Agent mode in your chat panel. Cursor will immediately recognize the tools.

They do exactly that. The agent calls debug_trace_transaction on your failed hash. It reads the stack trace and highlights the exact line in your smart contract that triggered the failure.

The integration includes eight dedicated Aptos tools. Cursor can pull deployed Move modules using aptos_get_account_modules and write frontend code that perfectly matches those data structures.

These are custom endpoints that aggregate blockchain data. Instead of writing complex loops to fetch an address's ERC20 balances, Cursor just calls nr_get_token_balance_20 to get the final numbers.

The server only processes public parameters like block heights, contract addresses, and transaction hashes. Vinkius runs the connection through a zero-trust, ephemeral sandbox. No proprietary source code from your local workspace is ever sent to the blockchain nodes.
