How to Use the BulkSMS MCP in Mastra AI

Q: How do I register the BulkSMS MCP Server tools inside Mastra AI?

Install @mastra/mcp and instantiate the client with your Vinkius URL. Call mcpClient.listTools() and spread those tools directly into your Mastra Agent instance to give it SMS capabilities.

Q: Can Mastra AI require manual sign-off before BulkSMS sends a text?

Yes, you can use Mastra's requireToolApproval feature on sendsms or sendbulksms. This pauses the workflow and waits for a human to confirm the text content before it gets sent to BulkSMS.

Build reliable SMS workflows with Mastra AI and handle text dispatches with built-in retries.

Handle text delivery failures with Mastra AI workflows

The `send_sms` and `get_message` tools form the backbone of your automated notification sequences. If a text delivery fails, Mastra's workflow engine catches the error, waits, and triggers a retry without crashing your application. You map these tools into your agent config using `listTools`. The MCP Server lets the agent check the message status using `get_message` after a set delay to confirm delivery before moving to the next step in your business logic.

Segment contacts dynamically using Mastra AI

The `list_groups` and `list_group_members` tools let your agent pull live distribution lists directly from your BulkSMS account. Your workflow can query these groups, filter out inactive members, and prepare targeted text campaigns. Instead of hardcoding list IDs, your Mastra agent inspects the group structures dynamically. It matches user profiles with specific lists and updates your team on the group sizes before executing any sends.

Prevent campaign halts with this MCP Server

The `get_profile` and `get_account_info` tools allow your Mastra agent to query your credit balance before executing any heavy workflows. If the balance falls below a threshold, the workflow branches to notify an admin instead of attempting to send. This conditional branching ensures you never run out of credits mid-campaign. The agent manages the pre-flight checks autonomously, keeping your messaging pipelines running smoothly.

Setup guide

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

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

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

Common questions about BulkSMS MCP in Mastra AI

Install `@mastra/mcp` and instantiate the client with your Vinkius URL. Call `mcpClient.listTools()` and spread those tools directly into your Mastra Agent instance to give it SMS capabilities.

Yes, you can use Mastra's `requireToolApproval` feature on `send_sms` or `send_bulk_sms`. This pauses the workflow and waits for a human to confirm the text content before it gets sent to BulkSMS.

Mastra's workflow engine handles rate limits using exponential backoff. If `send_bulk_sms` returns a rate-limiting response, the workflow pauses and retries the dispatch automatically.

No, the Mastra MCP client automatically detects whether the Vinkius endpoint is using Streamable HTTP or SSE. It manages the connection lifecycle behind the scenes so you can focus on writing agent logic.

Your BulkSMS API credentials are encrypted and stored securely within Vinkius. All data runs through an ephemeral MCP environment, injecting your credentials only when Mastra triggers a tool, ensuring your account profile details are never exposed to the client.
