An MCP server that provides Bitcoin data and operations for AI agents, including fee recommendations, mempool analysis, block and transaction inspection, mining, network status, and address/UTXO utilities. It can run zero-config against the hosted Satoshi API or connect to a local Bitcoin Core node.

From the registry: 49 Bitcoin tools for AI agents: fees, mempool, blocks, mining, price. Zero config.

Please install the `bitcoin-mcp` MCP server into my current AI client (that's you).

Optional prerequisites:
- Satoshi API key (optional free key) — Register for a free key at bitcoinsapi.com to unlock hosted lookups. (https://bitcoinsapi.com)

Canonical MCP server config (stdio transport):
- command: `uvx`
- args: ["bitcoin-mcp"]
- optional environment variables:
  - `SATOSHI_API_KEY`: Free bitcoinsapi.com API key (example: `<your-satoshi-api-key>`)
  - `BITCOIN_NETWORK`: Bitcoin network (mainnet, testnet, signet, regtest) (example: `mainnet`)
  - `SATOSHI_API_URL`: Override hosted API URL (example: `https://bitcoinsapi.com`)

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
