Mcp Block Data

Overview

Mcp Block Data is a Model Context Protocol (MCP) server: MCP server for retrieving block-level data from EVM, UTXO, and XRP blockchains via Crypto APIs. In practice that means any MCP-compatible AI assistant can call Mcp Block Data's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @cryptoapis-io/mcp-block-data speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need CRYPTOAPIS_API_KEY. The current release is v0.3.0, with source at CryptoAPIs-io/cryptoapis-mcp-block-data on GitHub.

Mcp Block Data is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
