Overview

What is Linea MCP Server?

Linea MCP Server is a Model Context Protocol (MCP) server that provides on-chain tools for AI applications to interact with the Linea blockchain, an Ethereum Layer 2 scaling solution using zero-knowledge proof technology. It enables AI assistants like Claude, Cursor, and other MCP-compatible clients to perform blockchain operations through natural language requests.

How to use Linea MCP Server?

Install globally via npm install -g linea-mcp or from source by cloning the repository and running npm install. Configure environment variables (RPC URLs, wallet private key, Infura API key) in a .env file. Integrate with any MCP-compatible client by editing the client’s MCP configuration file (e.g., mcp.json for Cursor or claude_desktop_config.json for Claude Desktop) and adding a linea server entry using either the global npx approach or a local Node.js path.

Key features of Linea MCP Server

  • 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 liquidity pools, swaps, yield farming
  • Verax integration: verify identity with Linea Verax attestations
  • Linea ENS: resolve and manage Linea ENS names

Use cases of Linea MCP Server

  • Query blockchain data and wallet balances via natural language
  • Transfer ERC20 tokens or NFTs using an AI assistant
  • Deploy and interact with smart contracts without manual RPC calls
  • Bridge assets between Ethereum mainnet and Linea
  • Verify on-chain identity or manage Linea ENS names

Frequently asked questions

1

What are the prerequisites to run the server?

Node.js v16+, npm or yarn, and access to Linea RPC endpoints (mainnet or testnet).

2

How do I install and configure the server?

Install globally with `npm install -g linea-mcp`, create a `.env` file with your RPC URLs, wallet private key, and Infura API key, then run `linea-mcp`. Alternatively, clone the repo, install dependencies, build, and run `node dist/index.js`.

3

How do I integrate Linea MCP Server with my AI client?

Find your client’s MCP configuration file (e.g., for Cursor: `mcp.json`, for Claude Desktop: `claude_desktop_config.json`) and add a `linea` server entry with the appropriate command, args, and environment variables. Use `npx linea-mcp@latest` for simple setups or a local path to the built `index.js` for development.

4

What should I do if I see “No tools available” or “Client closed” errors?

Use direct Node.js execution (`"command": "node"`, `"args": ["/path/to/dist/index.js"]`) instead of npm scripts, ensure all environment variables are set correctly, and restart the client after configuration changes.

5

Where are the configuration files located for popular clients?

For Cursor: `%APPDATA%\Cursor\mcp.json` (Windows), `~/Library/Application Support/Cursor/mcp.json` (macOS), `~/.config/Cursor/mcp.json` (Linux). For Claude Desktop: `%APPDATA%\Claude\claude_desktop_config.json` (Windows), `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS), `~/.config/Claude/claude_desktop_config.json` (Linux). For other clients, refer to their documentation.
