Overview
A Model Context Protocol (MCP) server that provides access to the Tatum Blockchain Data API and RPC Gateway, enabling any LLM to read and write blockchain data across 130+ networks. This official Tatum MCP server connects to any LLM in seconds and can be installed globally or locally. Get your free API key from Tatum Dashboard and configure the MCP client to use the server via npx @tatumio/blockchain-mcp, supplying the API key in environment variable TATUM_API_KEY. The server offers a Blockchain Data API for blocks, transactions, balances, network info, and more, alongside an RPC Gateway exposing direct RPC endpoints for supported networks. Supported networks include 69 EVM-compatible networks and 61 non-EVM networks, covering major blockchains such as Ethereum, Polygon, Solana, Bitcoin, and more. Documentation and licensing: MIT. This makes it easy for developers to empower LLMs with blockchain capabilities in a scalable, secure way.
