Compatible with every major AI agent and IDE
What is the UTM Campaign Builder MCP Server?
When a Martech AI Agent drafts social media posts or email campaigns, it needs to append tracking data to the links (UTMs). LLMs are notorious for hallucinating query strings—adding double ??, forgetting to URL-encode spaces, or breaking existing parameters. This ruins data attribution in Google Analytics. This MCP solves that perfectly.
The Superpowers
- Strict URL Encoding: Merges
utm_source,utm_medium, and other parameters cleanly into any base URL using strict browser-grade encoding. - Analytics Protection: Guarantees that every generated link works perfectly without causing 404s or dropping tracking data.
Built-in capabilities (1)
Provide the base landing page URL, utm_source, and utm_medium as required fields. Optionally add campaign, term, and content. The engine handles all URL encoding and query string merging safely. Safely constructs and encodes marketing UTM tracking URLs. Prevents AI from hallucinating broken query strings
Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 1 tools from UTM Campaign Builder through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries UTM Campaign Builder, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Frequently asked questions
What if the base URL already has parameters?
The engine safely detects existing parameters and appends the UTMs using & instead of ?, preserving all previous data.
Does it URL-encode spaces in the campaign name?
Yes. A campaign name like Summer Sale will automatically be encoded to Summer+Sale or Summer%20Sale.
Which UTM parameters are mandatory?
Only source and medium are mandatory. The engine will throw an error if the agent forgets to provide them.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
