How to Use the iFax MCP in Mastra AI

Q: How do I register the iFax MCP Server in a Mastra AI agent?

Install @mastra/mcp and instantiate the client with the Vinkius server URL. This registers the MCP server tools dynamically. Spread the tools directly into your agent configuration to give it faxing capabilities.

Q: Can I use Mastra AI to automatically cancel an iFax transmission?

Yes. You can build a workflow step that calls cancelfax if a specific condition is met, such as a timeout or a user cancellation request.

Q: Does the iFax integration with Mastra AI support human-in-the-loop?

Yes. You can configure requireToolApproval on the sendfax tool so an admin must approve the document before the agent actually transmits it.

Build automated fax workflows with Mastra AI to handle failed transmissions, retries, and conditional routing.

Automate Fax Retries with Mastra AI Workflows

The `resend_fax` tool integrates directly into your agent's conditional branching logic to handle delivery failures. When a transmission fails, Mastra AI automatically triggers this tool using exponential backoff rules. You define these rules in a single workflow file. It's that simple to ensure high-priority documents reach their destination without manual intervention.

Conditional Routing Based on Document Status

The `get_fax_status` tool lets your Mastra agent monitor active transmissions and branch your business logic accordingly. If a fax remains pending, the workflow pauses or alerts an administrator. You can also use `list_faxes` to audit recent transmissions before initiating new ones. This prevents your agents from sending duplicate documents to the same recipient.

Secure Document Retrieval and Local Storage

The `download_fax` tool pulls incoming documents directly into your automated pipelines. Your agent reads the incoming file, saves it to your storage bucket, and triggers the next step in your workflow. If a user cancels a workflow, the agent calls `cancel_fax` to stop any outbound queues. This keeps your automated pipelines clean and avoids unnecessary billing charges.

Setup guide

Set up iFax MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All iFax tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "ifax-mcp-client",
  servers: {
    "ifax-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "iFax Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to iFax tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent iFax transactions"
);
console.log(result.text);
