How to Use the Twilio MCP in Mastra AI

Q: Can Mastra AI manage complex Twilio call flows?

Yes. You can build multi-step logic that involves calling createvoicecall, waiting for confirmation, and then conditionally running cancelactivecall if the goal isn't met.

Q: What happens when I need to check account info with Twilio using Mastra AI?

Mastra AI executes getaccountinfo as a reliable step in your workflow. It provides the current master status and ensures that subsequent steps only run if the foundational data is valid.

Q: What type of data does this MCP Server touch regarding privacy?

This server touches SMS message records. Calling deletemessage permanently removes the body and metadata, which is irreversible, requiring careful workflow design.

Perplexity

Send SMS and Handle Failures

Use `send_sms` to dispatch a message. If the delivery fails or needs correction, your workflow engine automatically handles retries with exponential backoff. The system doesn't just fail; it tries different methods until it gets confirmation. This is crucial for reliable communication workflows where you can't afford simple failure points.

Manage Voice Calls and Recordings

You can initiate a call using `create_voice_call` and manage the state change. Need to end it? Call `cancel_active_call`. For post-call analysis, use `get_recording_details`, ensuring you get all metadata for every recording SID (RE). Mastra AI ensures that even complex voice workflows—like calling, waiting, and canceling—are managed reliably.

Audit Account Status and Usage

Need to know if the account is healthy? Run `get_account_info` to get the master status. You can also track spending by calling `get_usage_records`. The framework manages these data checks, guaranteeing that your complex logic always runs against current facts. It also lets you list and manage resources like call queues using `list_call_queues`.

Setup guide

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

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

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

Common questions about Twilio MCP in Mastra AI

Mastra AI incorporates automatic retries with exponential backoff. If the initial `send_sms` attempt fails, the workflow automatically tries again using a different method or delay until success is confirmed.

Yes. You can build multi-step logic that involves calling `create_voice_call`, waiting for confirmation, and then conditionally running `cancel_active_call` if the goal isn't met.

Mastra AI executes `get_account_info` as a reliable step in your workflow. It provides the current master status and ensures that subsequent steps only run if the foundational data is valid.

Absolutely. Its built-in workflow engine handles conditional branching; for example, 'if `get_message_details` shows an error, then retry the message send.'

This server touches SMS message records. Calling `delete_message` permanently removes the body and metadata, which is irreversible, requiring careful workflow design.
