How to Use the Authkey MCP in Mastra AI

Q: How do I configure Authkey in Mastra AI?

Initialize a new MCPClient with your Vinkius endpoint URL. Mastra auto-detects the Streamable HTTP transport and exposes the messaging tools to your agent via MCP.

Q: Can Mastra AI retry failed Authkey MCP Server messages?

It does this automatically. If sendemail or sendsms drops due to a network error, the workflow engine applies exponential backoff and tries again.

Q: How do I chain Authkey OTP verification in Mastra AI?

You create a multi-step sequence. Step one calls sendotp. The workflow pauses for user input, then step two executes verifyotp to confirm the pin.

Q: Does the framework monitor account credits?

You can schedule a workflow that runs checkbalance daily. If the credits drop below a specific threshold, the agent triggers an alert.

Branch Mastra AI workflows on Authkey status

The `get_sms_status` and `get_email_status` tools let your agent route logic based on message delivery. If an SMS bounces, your workflow automatically falls back to an email. You configure this by spreading `mcpClient.listTools()` into your Mastra agent. The framework handles the conditional branching, retrying failed deliveries using built-in exponential backoff.

Send bulk campaigns with error handling

The `send_bulk_sms` tool dispatches thousands of messages while Mastra monitors the execution. The agent pulls templates via `list_templates` and queues the outbound texts. Network blips happen. Mastra catches timeouts and automatically re-runs the tool. You get guaranteed execution without writing custom retry wrappers around the API calls.

Require human approval for voice alerts

The `send_voice` tool initiates phone calls for critical system alerts. You can enforce manual sign-off before the system dials an administrator at 3 AM. Set `requireToolApproval` on the MCP Server configuration. The workflow pauses, alerts a human operator, and only executes the voice call after receiving explicit permission.

Setup guide

Set up Authkey 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 Authkey 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: "authkey-mcp-client",
  servers: {
    "authkey-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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