pip install bitcoin-mcp

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"]
    }
  }
}

Claude Code

claude mcp add bitcoin -- uvx bitcoin-mcp

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"]
    }
  }
}

VS Code

Add to .vscode/mcp.json:

{
  "servers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"]
    }
  }
}

Zed

Add to your Zed settings.json under context_servers:

{
  "context_servers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"]
    }
  }
}

See the Zed MCP docs for the current settings location and custom server flow.

Docker

docker build -t bitcoin-mcp .
docker run -i bitcoin-mcp

Or with docker compose:

docker compose up

Pass environment variables to connect to a local Bitcoin Core node or set your API key:

docker run -i -e SATOSHI_API_KEY=your-key bitcoin-mcp

Ask whether to send Bitcoin now

Use this as the first useful activation path after install:

"I need to send a Bitcoin transaction today. Use bitcoin-mcp to decide whether to send now or wait, and show the fee rate you used."

Expected path:

1. The agent calls get_fee_recommendation.
2. The answer gives a clear send now or wait recommendation with fee rates in sat/vB.
3. If you will repeat this check, register a free Satoshi API key and add SATOSHI_API_KEY to your MCP config.
4. If you need a one-off paid API call instead of the MCP tool, use https://bitcoinsapi.com/x402/start.

After it works, Star this repo and share a short showcase with the prompt, tool call, and outcome so other Bitcoin agent builders can see the path.

Agent Integration

For repos that need Bitcoin tools, add bitcoin-mcp to the agent's MCP config and link the Satoshi API integration kit:

• Satoshi API agent guide: https://github.com/Bortlesboat/bitcoin-api/blob/main/docs/AGENT_INTEGRATION.md
• Agent-readable overview: https://bitcoinsapi.com/llms.txt
• MCP setup: https://bitcoinsapi.com/mcp-setup
• x402 first paid call: https://bitcoinsapi.com/x402/start

Generated HTTP examples should use canonical Satoshi API /api/v1 paths.

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, or connect your own Bitcoin Core node
• First Bitcoin MCP server on the Anthropic Registry

Utility

Get More Requests (Free)

bitcoin-mcp works immediately with 1,000 requests/day (anonymous). Register for a free API key to get 10,000/day (10x):

1. Visit bitcoinsapi.com
2. Register for a free key (takes 10 seconds)
3. Set the SATOSHI_API_KEY environment variable in your MCP config

Configuration

All environment variables are optional. bitcoin-mcp falls back to the free hosted Satoshi API when no local node is configured.

CLI Flags

bitcoin-mcp supports the following runtime flags:

Example:

bitcoin-mcp --transport sse --host 127.0.0.1 --port 8000 --log-level DEBUG

To connect to a local Bitcoin Core node:

{
  "mcpServers": {
    "bitcoin": {
      "command": "uvx",
      "args": ["bitcoin-mcp"],
      "env": {
        "BITCOIN_RPC_HOST": "127.0.0.1",
        "BITCOIN_RPC_PORT": "8332"
      }
    }
  }
}

Prompts & Resources

6 built-in prompts for common workflows: analyze_fee_environment, investigate_transaction, monitor_mempool_fees, taproot_adoption_report, network_health_report, track_transaction

8 resources for context injection: bitcoin://connection/status, bitcoin://node/status, bitcoin://fees/current, bitcoin://fees/history, bitcoin://mempool/snapshot, bitcoin://protocol/script-opcodes, bitcoin://protocol/address-types, bitcoin://protocol/sighash-types
