Getting the Most Out of Summer (and What Marketing MCP Means for You)

Sep 4, 2026

Marketing MCP is the connection that lets Claude/ChatGPT read your marketing data and answer questions about channels, campaigns, or clients, right inside the chat. Summer runs on it; instead of hunting for answers across Meta, Google Ads, Shopify, GA4, Klaviyo, and a few manually updated spreadsheets, you can just ask and get a verified answer with a receipt behind every number.

We wanted to make marketing data a pleasure, so we built Summer to be the one layer powering all marketing needs. Summer connects to marketing platforms directly, letting you ask plain questions about your data instead of hunting for answers. Every answer comes with a receipt, showing exactly where the number came from, so you can verify instead of blindly trusting. Oh, and one more thing we forgot to mention: Summer normalizes all definitions and metrics no matter what platform they come from, so that you are always comparing apples to apples.

Meet Sunni, your marketing data guru, ready to answer any question or build any report you ask for, receipt included every time.

Step 1: Connect Your Data

Log into Summer and go to Channels. You'll see the platforms you already use; Meta Ads, Google Ads, LinkedIn Ads, Shopify, and others depending on your setup. Click on any of them to connect, sign in the normal way, and authorize only the accounts you need.

Step 2: Connect Summer to Claude or ChatGPT

This connection is called MCP, and it lets you work directly with your data via Claude or ChatGPT. You can use Summer’s MCP to ask questions, build reports, or schedule tasks.

Once you set up a channel, you'll see Ask AI in the top right corner. That button leads you to the MCP connection instructions, which take about a minute to complete in your AI assistant of choice.

Step 3: Ask Your First Question

Type a question the way you'd ask an analyst, a manager, or your peer. Start simple, something like "Use Summer and tell me what we spent on Meta ads last month." Once you’ve confirmed the MCP connection is working correctly, go crazy, try something like "Use Summer to compare our Meta and Google ad spend for the last 30 days, tell me which campaign is driving the most conversions, and flag anything that looks off." Summer can handle it.

Ask Summer any question about your marketing data

Next to every number there is a receipt. Click it and you'll see the source, table, and formula behind each result in case a client is disputing it or wants an audit trail.

Step 4: Build and Share a Report

Ask Summer to build a report and it generates one with your branding applied. You can easily share links to these reports with clients or peers, no need for emailing PDFs around.

What's Next for You

Once your data's connected through the marketing MCP, here's what changes, for you and for every agency already running on Summer:

Your team gets back the hours they used to spend building spreadsheets. Ask for a cross-channel CTR comparison and the number is just there, no pivot table required.
You start making campaign decisions on numbers that actually match. Google and LinkedIn spend show up side by side, both counting "conversion" the same way.
Your team answers any client question on the spot, no analyst needed. "Is the new ad set outperforming the old one?" comes up mid-call, and the answer is already on screen.
You catch a campaign losing money in a day, not weeks. A quick check over coffee shows how every campaign's doing, and any drift stands out immediately.
You take on more clients without hiring more people. One person runs what used to take three, and the next client doesn't mean a new job posting.
You see the whole buyer journey, not just the ad click. Ad spend, site visits, and signups line up in one view, from first impression to conversion.
You stop losing a full day every month to client reporting. Ask for the report and get it back branded for each client and ready to share.
You earn client trust, because every number comes with its receipt. A client asks where a number came from and gets the source on the spot, not a promise to check and get back to them.
