Overview

AI-generated overview

SuguFAX lets an assistant check fax prices, send faxes to Japan using prepaid AI credits, track delivery status, and check the credit balance.

What you can do
Check fax pricing and whether a destination number is supported, without sending anything. Send a fax to Japan using one AI credit per fax, from an uploaded file, an attached file, a public PDF link, or small base64 data, optionally scheduled in Japan time. Track a sent fax's status and get the completion report link. Create a one-time upload link (valid 30 minutes) for documents from a phone or computer. Check the remaining AI credit balance.
When to use it
Use it when you need to send documents by fax to Japanese recipients from an AI conversation, or to check pricing, delivery status and remaining credits before and after sending.
Requirements
A remote endpoint at sugufax.com over streamable HTTP. A bearer token in the Authorization header, using an AI credit key obtained from the provider's credits page. Prepaid AI credits are needed to actually send faxes. Documents must be PDF, JPG or PNG, up to 10MB and 100 pages.
Before you install
Sending a fax consumes one prepaid AI credit per fax and is a real, irreversible delivery to a third party. The Authorization header carries a secret credit key. Upload links are one-time and expire after 30 minutes. Some destination numbers, such as mobile numbers and certain prefixes, are not supported.

Installation

In SourceWeft

  1. Open すぐFAX SuguFAX – AI fax credits (API key) in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.sugufax%2Ffax-credits/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
