Overview

AI-generated overview

FaxSeal lets an AI assistant send, receive, quote and verify faxes through the FaxSeal service, using credits from a FaxSeal account.

What you can do
  • Send faxes from a public PDF URL or from typed text that FaxSeal converts to PDF
  • Estimate page count and credit cost before sending
  • Check delivery status of a sent fax job
  • Check the account's remaining credit balance
  • List received faxes in the inbox with OCR text
  • Verify cryptographic delivery attestation via Sigstore/Rekor
When to use it
Useful when an assistant needs to send documents such as referrals or letters to a fax number, or to check delivery status and read incoming faxes, without leaving the chat.
Requirements
A FaxSeal account and API key supplied as the FAXSEAL_API_KEY environment variable. Runs either as a remote streamable HTTP endpoint or locally via the npm package faxseal-mcp (Node.js/npx). OAuth authentication is declared. Sending requires a publicly accessible PDF URL or text content.
Before you install
Sending a fax spends money from the FaxSeal credit balance, billed per fax from about $0.83. The API key is a secret and should not be shared. Sending transmits document content and the recipient's fax number to FaxSeal and the receiving party; check that this is appropriate for the material.

Installation

In SourceWeft

  1. Open FaxSeal in the dashboard and add it to a workspace.
  2. Connect the required 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/io.github.grichardomi%2Ffaxseal/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
