How to Use the SmartLead MCP in Mastra AI

Q: Can Mastra AI manage multiple SmartLead campaigns?

Absolutely. You can write workflows that iterate through listcampaigns, checking the status of each one and executing different actions (like pausing or resuming) based on predefined business logic.

Q: Does the MCP Server support advanced SmartLead functionality with Mastra AI?

Yes. The server exposes tools like getcampaignanalytics that can be incorporated into conditional steps, allowing your workflow engine to make decisions based on performance data.

Automated Lead Funneling

When you call `add_lead`, your agent handles the entire workflow. If adding a lead fails due to an API error, the system automatically retries with exponential backoff until it succeeds or notifies the admin. This ensures that even if initial outreach attempts fail, the critical process of capturing and logging new contacts completes without manual intervention.

Campaign Failure Handling

The `pause_campaign` tool lets you halt a running campaign. If subsequent steps in your workflow depend on that campaign running, Mastra detects the failure and can trigger an alternate path—like sending an alert or initiating a manual review. This level of conditional branching means your complex workflows don't just stop; they adapt to operational issues.

Account and Campaign Oversight

Your agent uses `list_email_accounts` to verify sending capacity before starting a job. It can then use `get_campaign` or `list_campaigns` to check the current status. This allows you to build complex pre-checks: 'Do we have 5 active accounts? Is Campaign X running?' If not, the workflow fails gracefully and suggests a fix.

Setup guide

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

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

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

Common questions about SmartLead MCP in Mastra AI

Mastra handles the complexity. You define the steps—list leads, then add them—and it manages retries and failure paths automatically. The workflow executes even if a specific API call fails initially.

Absolutely. You can write workflows that iterate through `list_campaigns`, checking the status of each one and executing different actions (like pausing or resuming) based on predefined business logic.

Mastra's built-in error handling catches these issues. Instead of failing completely, it can trigger a secondary process—like notifying an admin or switching to a different sending account.

Yes. The server exposes tools like `get_campaign_analytics` that can be incorporated into conditional steps, allowing your workflow engine to make decisions based on performance data.

The system manages Leads (via adding them), Campaigns (for running and pausing them), and Email Accounts (for rotation). The workflow relies heavily on the consistency of these three streams.
