Perplexity

Generate Flawless Tracking URLs in Workflows

The `build_utm_url` tool provides your agent the ability to generate perfect, encoded marketing UTM tracking URLs. Instead of struggling with syntax, your workflow engine just calls this single, reliable tool. This is crucial for multi-step processes where you need a clean link passed from one step to the next, regardless of potential failures.

Prevent Broken Google Analytics Routing

When building complex workflows in Mastra AI, tracking links can get messy fast. `build_utm_url` handles all URL encoding and query string merging safely for you. You don't have to write custom logic for it. It ensures that whether you are adding a source or a medium parameter, the resulting link is always valid.

Handle Required UTM Parameters Automatically

The tool requires the base landing page URL, utm_source, and utm_medium. Mastra AI’s workflow engine can enforce these required inputs before calling `build_utm_url`. This reliability means your agent won't proceed with a marketing campaign build if the essential tracking data is missing.

Setup guide

Set up UTM Campaign Builder 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 UTM Campaign Builder 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: "utm-campaign-builder-mcp-client",
  servers: {
    "utm-campaign-builder-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about UTM Campaign Builder MCP in Mastra AI

It manages it automatically. The `build_utm_url` tool takes all inputs and safely encodes them, preventing your agent from hallucinating broken query strings or invalid characters.

It works exclusively with URL strings. The server constructs marketing URLs based on required source, medium, and optional campaign/term parameters, ensuring the output is always a valid string.

Yes. You can pass the campaign, term, or content as optional arguments to `build_utm_url`. The workflow will then incorporate these specifics into the final tracking URL.

Definitely. By centralizing the logic for link generation, you don't need to build custom encoding handlers or worry about potential syntax errors within your workflow steps.

It is. Since the tool is designed specifically to safely construct and encode these links, it's reliable enough for large-scale operations that require perfect tracking from start to finish.
