すぐFAX SuguFAX – AI fax credits (API key)

Overview

すぐFAX SuguFAX is an MCP server that lets you send faxes to Japan directly from AI assistants using prepaid credits. Each credit equals one fax, and you authenticate with a Bearer sgx_ API key. The server exposes fax-sending as a tool your AI model can invoke automatically.

It runs as a hosted remote service at https://sugufax.com/api/mcp-credits.php—just point your MCP client there and you're ready to go. No local installation needed. The current release is v1.0.0. You'll need valid API credentials from sugufax.com and prepaid fax credits to use it.

すぐFAX SuguFAX appears in the AI & Agents category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, claim the listing to verify ownership, earn a Verified badge, and keep details up to date.
