Bitcoin MCP Server

Overview

The ₿itcoin & Lightning Network MCP Server bridges the gap between AI assistants and the Bitcoin ecosystem by exposing a rich set of tools that can be invoked through the Model Context Protocol. It allows models such as Claude to generate new key pairs, validate addresses, decode raw transactions, and query live blockchain data—all without leaving the conversational interface. For developers building AI‑powered financial applications, this means instant access to core Bitcoin functionality without the overhead of maintaining a full node or writing custom APIs.

What Problem Does It Solve?

Working with Bitcoin programmatically typically requires a dedicated node, RPC endpoints, or third‑party services that may introduce latency, cost, or privacy concerns. The MCP server consolidates these capabilities into a single, lightweight service that can be run locally or in the cloud. By integrating directly with an AI assistant, developers can ask natural‑language questions like “Show me the details of transaction X” or “Generate a new Bitcoin address for me,” and receive structured, actionable responses instantly. This streamlines prototyping, testing, and even production workflows where AI needs to interact with on‑chain data.

Key Features & Capabilities

• Key Generation – Create a full Bitcoin key pair (address, public key, WIF private key) with one command.
• Address Validation – Verify that a given address is syntactically correct and conforms to the expected network.
• Transaction Decoding – Convert a raw hex transaction into a human‑readable format, revealing inputs, outputs, and fees.
• Blockchain Queries – Retrieve the latest block details or look up any transaction by TXID, exposing metadata such as height, timestamp, and size.
• Lightning Network Support – Decode BOLT11 invoices into readable fields (amount, expiry, description) and send payments directly from an LNBits wallet.
• Seamless AI Integration – Exposes all tools via MCP, enabling Claude Desktop and Goose (and any future MCP‑compliant client) to call them as part of a broader conversational workflow.

Real‑World Use Cases

• Developer Tooling – Quickly validate addresses or inspect transaction data while debugging smart contracts or wallet integrations.
• Educational Platforms – Build interactive tutorials where students can ask an AI to walk them through creating keys or decoding a transaction.
• Financial Chatbots – Enable chat interfaces that can generate new addresses for deposits, verify incoming payments, or display blockchain statistics on demand.
• Lightning Payment Bots – Automate invoice parsing and payment routing directly from conversational prompts, useful for customer support or automated billing systems.

Integration Into AI Workflows

Because the server speaks MCP, any client that understands the protocol can tap into its functionality. Claude Desktop users can add the server via a simple URL, while Goose and other open‑source assistants can consume the same endpoints. The server’s responses are structured JSON objects that AI models can embed directly into replies, allowing for dynamic content generation—such as rendering a transaction table or embedding an LN invoice in the chat. This tight coupling eliminates round‑trip latency and ensures that AI assistants can act as first‑class interfaces to the Bitcoin network.

Unique Advantages

• Zero‑Code Interaction – Developers can invoke complex blockchain operations with plain natural language, no need to write RPC calls or SDK wrappers.
• Privacy‑First – Running the server locally keeps all key material and transaction data on the user’s machine, avoiding third‑party exposure.
• Extensibility – The MCP architecture allows additional tools (e.g., wallet management, multi‑signature orchestration) to be added later without changing client logic.
• Cross‑Platform Compatibility – Works with any MCP‑compliant tool, making it future‑proof as new assistants emerge.

In summary, the ₿itcoin & Lightning Network MCP Server transforms AI assistants into powerful Bitcoin explorers and transaction managers, providing developers with an effortless bridge between conversational interfaces and the blockchain’s core primitives.
