mcp-blockchair

Blockchair MCP — multi-chain block explorer (free tier, keyless).

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

Tool	Description
`stats`	Chain-wide stats.
`block`	Block details by hash or height.
`transaction`	Transaction details by txid.
`address`	Address dashboard (balance + recent txs).
`node`	Node software stats (sync status, version, latest block, …).

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

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

Or connect to the full Pipeworx gateway for access to all 673+ data sources:

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

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

ask_pipeworx({ question: "your question about Blockchair data" })

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