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

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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
