Tatum Blockchain MCP server

Lets your AI look up blockchain data like balances, transactions, and crypto prices across many networks.

This is a helper for your AI that connects it to Tatum, a service that reads data from many blockchains. Once it is set up, you can just ask your AI questions about crypto wallets, blocks, and prices, and it will go look up the real numbers for you. It is handy for anyone who works with crypto data but does not want to click around block explorer websites all day.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to Tatum, which is a service that reads data from over 130 blockchains. So when you ask about a wallet or a coin, your AI can reach out through this helper and bring back real, current information.

What this MCP server does

You ask your AI a question in normal words, like what a wallet holds or what a coin is worth. Your AI passes that request to this helper program running on your computer. The helper talks to Tatum's servers, which read the blockchain for you. Tatum sends the answer back, and your AI shows it to you in the chat as a list, a number, or a short summary. You never have to visit a blockchain website or copy long addresses around.

Flow diagram: you ask your AI “What is the BTC to USD exchange rate?”, the Tatum Blockchain MCP server connects it to Tatum, and you get back answer in your chat.

“Is this wallet address known to be malicious?”

What it gives back to you

You get answers in your chat window, in plain language. Depending on what you asked, that could be a number like a price or a block height, a list of transactions, a wallet portfolio broken into coins and NFTs, or a short yes or no on a security check. Your AI usually adds a sentence or two explaining what it found.

Before you start

What you need

A free Tatum account and API key from dashboard.tatum.io (an API key is like a password your apps use to talk to a service)
Node.js 18 or newer installed on your computer
An MCP client like Claude Desktop, Cursor, or VS Code

Good to know

It only reads blockchain data, so it will not move or spend your crypto, but it does need your Tatum API key, so keep that key private.
