How to Use the Lineascan MCP in Cursor

Q: How do I add the Lineascan MCP server to my Cursor project?

Add the server configuration to your .cursor/mcp.json file in the root directory. Paste your API key in the arguments list to let Cursor connect to the Linea network.

Q: Can Cursor use Lineascan to monitor multiple wallet balances during local development?

Yes, Cursor calls balancemulti to fetch the current ETH balances of several test accounts at once. This helps you verify that your deployment scripts funded the correct addresses.

Q: Does the Lineascan integration with Cursor support real-time gas estimation?

Yes, the server exposes ethestimategas which Cursor uses to calculate transaction costs. You can test your contract execution costs against the current ethprice directly in the chat panel.

Q: How do I fetch historical event logs using Lineascan in Cursor?

The server provides the getlogs tool to filter and fetch historical event logs. Cursor reads these logs to help you write accurate event listeners for your decentralized application.

Run live Linea network queries directly inside Cursor to generate code from real blockchain state.

Inject Real Blockchain Data into Cursor

This Lineascan MCP server delivers live transaction receipts and block data directly to your active file. The server queries `eth_get_transaction_receipt` to pull execution statuses so your agent writes code against actual network responses. You don't have to rely on outdated mocks or stale JSON files during local testing. Cursor reads the real-time block state through `eth_get_block_by_number` and updates your frontend components with live data.

Generate Typed Interfaces from Verified ABIs

This integration retrieves contract ABIs to generate TypeScript interfaces inside your editor. The server uses `get_abi` to fetch the verified interface and feeds it to the Cursor agent. The agent reads the JSON payload and instantly writes typed contract wrappers. You save time because you never copy-paste ABIs from an external browser window again.

Debug Failed Transactions Inside the Editor

This Lineascan MCP tool suite analyzes failed transactions by reading transaction hashes. The server calls `eth_get_transaction_by_hash` and `get_status` to pinpoint the exact step where an execution reverted. Cursor takes this error data to suggest code fixes for your smart contract or frontend submission logic. You debug the entire lifecycle without leaving your workspace.

Setup guide

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