Cursor Agent integration for live chain state

Cursor Agent mode can now call your blockchain nodes directly while you write code. It pulls current block data using `eth_block_number` to ensure your logic matches the chain. This eliminates the need for hardcoded stubs. Your agent writes code based on the actual output of `eth_call`, ensuring your integration tests reflect reality.

Automated gas estimation in Cursor

Stop guessing gas limits for your contract deployments. Let your agent query the network and set the correct parameters before you commit. Running `eth_estimate_gas` within your editor provides accurate figures based on current network congestion. You get reliable deployment scripts without the usual trial and error.

On-chain verification inside Cursor

Verify your contract state without manual lookups. Your agent can fetch account code or balances to confirm deployment success. Use `eth_get_code` or `sol_get_account_info` to see what is actually live on the network. It verifies your local changes against the state on-chain, keeping your development cycle tight.

Setup guide

Set up GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) transactions." If the MCP tools are loaded correctly, Cursor will call the GetBlock (Web3 RPC Provider) tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about GetBlock (Web3 RPC Provider) MCP in Cursor

Create an mcp.json file in your project root or home directory. Add the server configuration under mcpServers and reload the window to initialize the provider.

Yes. Once configured, the agent recognizes the available tools and will automatically invoke them when you ask about blockchain state or transactions.

Absolutely. You can configure the server to handle Ethereum, Bitcoin, and Solana simultaneously. Your agent will select the correct tool based on your project requirements.

The server only interacts with the RPC methods you explicitly call. It has no read or write access to your local source code unless you provide that context to the agent.

The server relies on the API key provided in your config. It does not store your private keys or sensitive wallet data; it only passes signed transactions you generate externally.
