You deploy the 0xGasless MCP Server to connect Claude AI with multiple blockchains, enabling gasless transactions and token operations directly from conversations. It provides a streamlined, secure way to interact with blockchain networks without holding native tokens, across several networks and with instant setup options.

How to use

Interact with your Claude conversations to perform gasless blockchain actions. You can retrieve your smart account address, check token balances, transfer tokens, swap assets, bridge tokens across chains, and purchase AI credits for OpenRouter-empowered features. Use natural language prompts to trigger these actions, for example asking for your wallet balance, initiating a token transfer, or swapping assets.

How to install

Prerequisites: you need Node.js installed on your system. You will also use npm or npx to install and run the MCP server locally.

# Global installation (recommended)
npm install -g 0xgasless/mcp

Additional setup and usage notes

Configuration involves supplying your blockchain connection details and API keys. You can use an automatic setup flow or a manual environment file. The automatic flow configures your environment and Claude Desktop integration with a single command. The manual flow requires you to create a .env file with required and optional settings.
