Data source

https://blockstream.info/api/ (mainnet) and https://blockstream.info/testnet/api/ (testnet) — both serve the Esplora REST API.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "blockstream-info": {
      "url": "https://gateway.pipeworx.io/blockstream-info/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Blockstream Info data" })

The gateway picks the right tool and fills the arguments automatically.
