Perplexity

Manage voicemails with conditional logic

Use `list_voicemails` as part of a complex Mastra-AI workflow to prioritize urgent messages. You can branch your agent logic based on the content or frequency of incoming voicemails. This prevents missed leads by ensuring important messages trigger specific follow-up actions. It automates the triage process that usually takes hours of manual work.

Coordinate calls with automated retries

Implement `make_call` within your agent workflows to handle outbound communication. If a call fails, the Mastra-AI engine handles the retry logic automatically, ensuring the connection attempt completes. This is essential for high-volume outreach where consistency matters. Your agents focus on the conversation while the framework manages the technical stability of the connection.

Sync business numbers across agents

Retrieve your available lines using `list_business_numbers` to assign specific agents to specific regions or campaigns. This allows for granular control over your telephony infrastructure. Your workflow engine keeps track of which line is active for which task. It simplifies the administrative overhead of managing multiple business phone numbers.

Setup guide

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

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

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

Common questions about MightyCall MCP in Mastra AI

You can enable requireToolApproval in your client configuration. This forces a human review before the agent executes sensitive actions like dialing a number.

The framework supports exponential backoff for tool execution. You can configure it to retry the `make_call` operation if the initial attempt is unsuccessful.

All interactions are handled through a secure, ephemeral connection. Your sensitive call data is never stored on the agent framework layer.

Absolutely. You can chain tools together, such as listing contacts and then initiating a call, within a single automated sequence.

Pass the specific tool definitions into your agent setup. This limits the agent to only the functions you choose to expose.
