Bitcoin MCP server
by JamesANZ
Ask your AI about any Bitcoin address, transaction, or block and get live answers.
This is a small helper that lets your AI look up real Bitcoin blockchain information for you. You ask a question in plain English, and it fetches live data from a public Bitcoin explorer called mempool.space. It is handy for anyone curious about Bitcoin who does not want to click around block explorer websites.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill. This one connects your AI to the Bitcoin blockchain, so when you ask about an address or a transaction, the AI can actually go look it up. It is like giving your AI a phone line to a Bitcoin data service.
What this MCP server does
You ask your AI something like how much has this Bitcoin address received. The AI sends that request to this helper program running on your computer. The helper then asks mempool.space, a public Bitcoin data service, for the answer. When the reply comes back, the AI reads it and explains it to you in the chat. You never have to visit a block explorer site yourself.
Click to zoomWhat you can do with it
- Check how much a Bitcoin address has received and spent
- See the recent transaction history for an address
- List the unspent coins (UTXOs) sitting at an address
- Look up the full details of a single transaction
- Get information about a block by its height
Try asking your AI
- “How much Bitcoin has address 1wiz18xYmhRX6xStj2b9t1rwWX4GKUgpv received and spent?”
- “Show me the last 5 transactions for this Bitcoin address”
- “What are the unspent outputs for this address right now?”
- “Tell me about Bitcoin block 857808”
What it gives back to you
You get back plain answers in the chat: amounts in Bitcoin, counts of transactions, dates, fees, and confirmation status. For a block, you get its hash, timestamp, size, and how many transactions it holds. For a transaction, you see its inputs, outputs, fees, and confirmations. It is all read-only information, nothing is changed.
Before you start
What you need
- Node.js 18 or newer installed on your computer
- An AI app that supports MCP servers, like Cursor or Claude Desktop
Good to know
It only reads public Bitcoin data, so it cannot move or spend anything, but the information it shows is live and can change as new blocks arrive.
Install it with your AI
Add Bitcoin MCP server to your AI, no technical skills needed
You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.
Sign in to get the install prompt
Members get a ready-made prompt that lets the Claude desktop app check Bitcoin MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
Who it's for
Anyone curious about Bitcoin who wants quick answers without learning block explorer websites, plus developers and researchers who check addresses and transactions often.
