Infura

infura-mcp is a MCP server that lets you query Ethereum blockchain data using Infura APIs. It translates natural language requests into on-chain data access, enabling you to fetch balances, blocks, transactions, and other Ethereum data through MCP-compatible endpoints with simple tooling.

How to use

You connect to the MCP server from a client that supports MCP endpoints. You’ll run a local or remote MCP server process that exposes the Ethereum data you need. You can enable read-only tools by default and, if you need write capabilities, toggle that option in the environment to unlock additional endpoints. When you query, you’ll access standard Ethereum data like account balances, blocks, transactions, logs, and more through the MCP interface.

How to install

Prerequisites: ensure you have Node.js and npm installed on your machine.

# Install dependencies
npm install

# Start the development server
npm run dev

Notes and usage details

Using the MCP with Claude Desktop or Docker is supported. You can run a local, self-contained MCP server via a simple command, or deploy via Docker to expose the service on port 3000. Make sure you provide your Infura API key or other required credentials, as shown in the example configuration.
