The Lebesgue MCP lets you bring your real-time Lebesgue data into the AI tools your team already uses like Claude and ChatGPT so you can ask questions about your marketing and advertising performance and get answers straight from your trusted Lebesgue data. It's a secure, read-only connection: your AI tool can analyze your data, but it can never change anything in your store, ad accounts, or Lebesgue account.
What Is the Lebesgue MCP?
MCP (Model Context Protocol) is an open standard that lets AI tools connect to outside data sources. The Lebesgue MCP uses that standard to give an external AI tool secure, read-only access to your Lebesgue data.
In short: it's the bridge between Lebesgue and the AI tool of your choice. Once it's connected, you can ask that tool questions about your revenue, spend, ROAS, attribution, pixel and visitor behavior, and more, and it will answer using your live Lebesgue numbers instead of guessing or asking you to export spreadsheets.
Step 1: Connect Lebesgue in Your AI Tool
You connect with a secure sign-in (OAuth) using your existing Lebesgue account. There are no API keys to generate, copy, or store.
Open your AI tool's connector settings. In Claude, ChatGPT, or any tool that supports MCP servers, go to the section where you add integrations or connectors.
Add Lebesgue. Select Lebesgue from the connector directory if it's listed, or add a new connection using the server address:
https://api.lebesgue.io/mcp
Sign in with your Lebesgue account. You'll be taken to a Lebesgue sign-in screen. Log in as you normally would.
Approve read-only access. Confirm the connection when prompted.
Once your connection is complete, you'll be able to ask that AI tool questions about your Lebesgue data right away.
What Can I Ask?
Anything you'd normally explore in Lebesgue, your AI tool can now help you analyze. For example:
Performance & spend — "What was my ROAS last week compared to the week before?"
Trends — "How has my ad spend trended across channels this month?"
Attribution — "Which channels drove the most revenue in the last 30 days?"
Investigation — "Why did my revenue drop last Tuesday?"
Summaries — Build a recurring check-in, like a weekly performance recap, inside your own AI tool.
Because the connection is live, you're always working with your current Lebesgue data no manual exports or copy-pasting.
How Is This Different From Henri?
Henri is the AI assistant built inside Lebesgue. The Lebesgue MCP is how you bring Lebesgue data into a different AI tool. The simplest way to think about it:
Use the Lebesgue MCP when you want to analyze your Lebesgue data inside an external tool like Claude or ChatGPT. It's read-only, great for questions, analysis, and summaries in the tools your team already lives in.
Use Henri when you want to go beyond analysis. Henri lives inside Lebesgue, understands Lebesgue's own metric and attribution definitions, and can help you act on what it finds across your marketing and advertising workflows, not just report on it.
Any reports, check-ins, or summaries you create through the MCP live inside your own AI tool. They aren't published or connected back to your business.
