This is a small helper that connects your AI assistant to the Bitcoin network and to Lightning. Once it is set up, you can just ask your AI questions about Bitcoin in normal words and it will fetch real answers. It is handy for anyone curious about crypto who does not want to learn a block explorer or a wallet tool.

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 one new skill or connection. This one connects your AI to Bitcoin and the Lightning Network, so it can look things up on the real blockchain and read or pay Lightning invoices for you. You stay in the chat; the helper does the technical work behind the scenes.

What this MCP server does

You ask your AI something about Bitcoin in plain words. Your AI passes that request to this helper program running on your computer. The helper talks to the Bitcoin network or to your Lightning wallet, gathers the answer, and hands it back. Your AI then explains the result to you in the chat. You never have to open a block explorer or copy long codes around.

Flow diagram: you ask your AI “What is the latest Bitcoin block?”, the Bitcoin MCP server connects it to Bitcoin network, and you get back answer in plain words.

Try asking your AI

“What is the latest block on the Bitcoin network?”
“Is this Bitcoin address valid: bc1q...”
“Decode this raw transaction for me and explain what it does”
“Decode this Lightning invoice and tell me the amount and who it is for”

What it gives back to you

You get answers written in normal language right in the chat. Depending on what you asked, that could be block details like height and time, a list of transaction details, a yes or no on an address, or a readable breakdown of an invoice. If you asked it to pay a Lightning invoice, it tells you whether the payment went through.

Before you start

What you need

The Claude desktop app or another AI app that supports MCP servers
Node.js installed on your computer so the npx command can run
For Lightning payments: an LNBits wallet and its connection details

Good to know

It can create real Bitcoin keys and, if you connect a Lightning wallet, it can send real payments, so be careful with what you ask it to do.
