Klaviyo MCP Server
Connect Klaviyo to Claude, ChatGPT or Perplexity and just ask. Ask AI runs a hosted MCP server that reads your live Klaviyo data — campaigns, flows, revenue, and list growth — alongside Shopify, GA4, ad spend, and 17 other sources, all queryable in a single conversation.

What is an MCP server?
MCP (Model Context Protocol) is an open standard developed by Anthropic that lets AI assistants query external data sources in real time during a conversation. Instead of exporting a report and pasting numbers into a chat window, the AI calls the MCP server directly and gets live answers from your actual marketing data.
For Klaviyo, this means Claude, ChatGPT or Perplexity can read your real campaign, flow, and revenue data — without digging through the Klaviyo dashboard. You ask a question, the AI queries your Klaviyo account via the MCP server, and you get an answer from your live data.
Ask AI runs the MCP server for you. You connect Klaviyo with a read-only API key, grab your MCP URL from the dashboard, and paste it into your AI tool. That's it.
What Klaviyo data is available via MCP
Once connected, your AI can query all of the following from your live Klaviyo account.
Campaigns — sends, open rate, click rate, attributed revenue
Flows — automated flow performance and revenue per recipient
Lists & segments — size, growth, and engagement over time
Subscribers — profiles, engagement, and consent status
Revenue — email- and SMS-attributed revenue by campaign and flow
Deliverability — bounce, unsubscribe, and spam-complaint rates
Connection method
Klaviyo private API key with read-only scopes — Ask AI can read your marketing data but can never send campaigns or edit your account.
How to set up the Klaviyo MCP server
Four steps. Takes under 5 minutes from start to first query.
Connect Klaviyo
Sign up and paste your Klaviyo private API key with read-only scopes. We can never send campaigns or edit your account. Historical data syncs in minutes.
Get your MCP URL
Go to AI Tools in your dashboard. Your unique Remote MCP Server URL is ready immediately. No configuration required.
Add to Claude, ChatGPT or Perplexity
In Claude: Settings → Connectors → Add Custom Connector → paste your URL. ChatGPT uses a Custom GPT and Perplexity supports Remote MCP directly. Takes under 2 minutes.
Start asking questions
Open a new conversation and ask anything about your email and SMS marketing. The AI queries your live Klaviyo data and returns real answers — no exports, no dashboards.
Example queries you can ask
Once your Klaviyo account is connected via MCP, ask your AI tool questions like these:
“Which Klaviyo campaigns drove the most revenue last month?”
“What's my average open rate trend over the last 6 months?”
“Which flows have the highest revenue per recipient?”
“How fast is my email list growing, and which sign-up source is best?”
“Which campaigns had high open rates but low clicks?”
“Compare flow revenue to campaign revenue this quarter.”
More powerful with your other tools
Klaviyo reports its own attributed revenue — but the real test is whether those campaigns drove actual sales. The same MCP server also exposes Shopify, Google Ads, Meta Ads, GA4, and 16 other sources alongside Klaviyo, so you can ask cross-platform questions no single dashboard can answer.
“Which Klaviyo campaigns drove the most actual Shopify orders this month?”
“Compare Klaviyo attributed revenue to real Shopify revenue — is attribution inflated?”
“Do my Klaviyo campaign sends line up with spikes in GA4 traffic?”
“Which segments have high email engagement but low repeat purchase rate?”

Frequently asked questions
What is a Klaviyo MCP server?
MCP stands for Model Context Protocol — an open standard developed by Anthropic that lets AI assistants like Claude query external data sources in real time. A Klaviyo MCP server gives Claude, ChatGPT or Perplexity direct, read-only access to your Klaviyo account so you can ask about campaigns, flows, revenue, and list growth in natural language — without exporting reports from Klaviyo.
How do I connect Klaviyo?
You paste a Klaviyo private API key into Ask AI. We recommend a read-only key so Ask AI can read your campaign, flow, and revenue data but can never send emails, edit flows, or change your account. Setup takes about a minute and historical data syncs shortly after.
Which AI tools can I use it with?
Claude (claude.ai Pro/Team and Claude Desktop) and Perplexity Pro support Remote MCP servers directly. ChatGPT connects via a Custom GPT and Gemini via function calling — Ask AI supports all of them from the same dashboard.
Can I combine Klaviyo with my Shopify and ad data?
Yes — that's where it gets powerful. The same MCP server also exposes Shopify, Google Ads, Meta Ads, GA4, and 20+ other sources. You can ask whether Klaviyo campaigns drove real Shopify orders, or whether attributed revenue matches actual sales, all in one conversation.
How accurate are email open rates?
Open rates are inflated across the whole industry by Apple Mail Privacy Protection, which pre-loads images and registers an 'open' even when the recipient didn't view the email. Ask AI treats clicks and attributed revenue as more reliable signals, and will flag open-rate figures accordingly so you don't over-read them.
Is my data secure?
All credentials, including your Klaviyo API key, are encrypted with AES-256-GCM at rest. We only need read access, and you can disconnect Klaviyo or revoke the key at any time from your dashboard.
