Overview

AI-generated overview

Remote MCP server exposing 17 Bitcoin full-node and research tools, with 3 free tools and 14 paid per call in USDC via x402.

What you can do
  • Read blockchain state: block height, difficulty, peers, fee estimates and mempool status (free tools).
  • Look up transactions by hash, address portfolios with balances, UTXOs and history, and trace transaction flow across two hops.
  • Predict fee rates and surface large Bitcoin movement alerts.
  • Pull SEC insider filings (Forms 4/3/5) and trace capital flows across markets.
  • Fetch a URL as clean markdown, summarize text, and run systems-theory or game-theory analysis.
  • Read Reddit: hot posts in a subreddit, keyword search and trending topics.
When to use it
Useful when an assistant needs live Bitcoin on-chain data, fee and mempool context, address or transaction tracing, or quick Reddit and SEC lookups without running a node or holding API keys. The free tools alone suit basic chain-status questions.
Requirements
Remote SSE endpoint at mcp.btcnode.uk/sse; no install, API keys or account needed. Paid tools require a wallet that can pay USDC on Base mainnet through the x402 protocol, approved in the MCP client. Self-hosting needs Node.js 18+ and a synced Bitcoin Core node.
Before you install
14 of 17 tools cost $0.001 in USDC on Base mainnet per call, so agent use spends real money; the wallet approves each payment in the client. Queries about addresses, transactions and URLs are sent to a third-party hosted service. Self-hosting requires editing a .env file with your own settings.

Installation

In SourceWeft

  1. Open IRONCLAW BTC Node in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.cariohca-ux%2Fbtc-node/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
