## Why bitcoin-mcp?

- **Fee intelligence that saves real money** — know the cheapest time to send, compare fee tiers, estimate exact costs before broadcasting
- **Zero config** — works instantly with the free hosted [Satoshi API](https://bitcoinsapi.com), or connect your own Bitcoin Core node
- **First Bitcoin MCP server on the [Anthropic Registry](https://registry.modelcontextprotocol.io)**

## Top Use Cases

Ask your AI agent:

| Prompt | What it does |
|--------|-------------|
| "What's the cheapest time to send Bitcoin today?" | Fee recommendation with savings breakdown |
| "Analyze the current mempool congestion" | Real-time mempool depth, fee tiers, pending tx count |
| "How much would I save waiting 6 blocks vs next block?" | Side-by-side fee comparison across confirmation targets |
| "Search for this transaction: abc123..." | Full transaction decode with inscription detection |
| "Give me a situation summary of Bitcoin right now" | Price, fees, mempool, mining, difficulty — one call |

To connect to a local Bitcoin Core node:

```json
{
  "mcpServers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"],
      "env": {
        "BITCOIN_RPC_HOST": "127.0.0.1",
