Audit Linea Contracts in Claude Desktop

This Lineascan MCP tool fetches verified smart contract source code and ABIs directly into your Claude Desktop chat window. Your agent pulls raw code using `get_source_code` and checks the interface with `get_abi` to analyze vulnerabilities. You don't have to open a web browser to get your raw source files. Claude Desktop uses these files to write test suites or explain complex contract logic on the spot.

Track Wallets and Token Transfers Instantly

The Lineascan integration queries real-time ERC-20 and NFT transaction histories for any wallet address. The server exposes `token_tx` and `token_nft_tx` to feed actual transfer events directly to your local workspace. Instead of clicking through block explorers, you ask Claude Desktop to parse the transaction history. It tracks incoming tokens and maps out address connections using your local system resources.

Verify Contract Deployments From Your Chat

This tool submits smart contract source code for verification on the Linea network. The server uses `verify_source_code` to submit your files and monitors the queue with `check_verify_status`. Claude Desktop reads your local build artifacts and pushes them to the verification API. You get confirmation directly in your terminal output without manual uploads.
