Mcp Broadcast

Overview

Mcp Broadcast is a Model Context Protocol (MCP) server: MCP server for broadcasting signed raw transactions to multiple blockchains via Crypto APIs. In practice that means any MCP-compatible AI assistant can call Mcp Broadcast'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-broadcast speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need CRYPTOAPIS_API_KEY. The current release is v0.4.0, with source at CryptoAPIs-io/cryptoapis-mcp-broadcast on GitHub.

Mcp Broadcast 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.
