What is the Linea MCP Server?

A Model Context Protocol (MCP) server that provides on-chain tools for AI applications to interact with the Linea blockchain.

What it actually does

Linea-MCP extends any MCP client's capabilities by providing tools to interact with the Linea blockchain, an Ethereum Layer 2 scaling solution using zero-knowledge proof technology. This server enables AI assistants like Claude, Cursor, and other MCP-compatible clients to perform blockchain operations through natural language requests.

  • Wallet Management — Retrieve addresses and check balances
  • Token Operations — Transfer ERC20 tokens, check balances, list tokens
  • Smart Contract Interactions — Deploy and call contracts
  • NFT Management — List and transfer NFTs
  • Bridge Operations — Bridge assets between Ethereum and Linea
  • DeFi Integrations — Interact with DeFi protocols

Configuration

  • Node.js (v16+) - npm or yarn - Access to Linea RPC endpoints
