Klaviyo MCP Server
Klaviyo's MCP server connects an assistant to email and SMS marketing data: campaigns, flows, profiles and reporting.
What it is and why it matters
Klaviyo's MCP server connects an AI assistant to your email and SMS marketing data. Retention teams can ask about campaigns, flows, segments and profiles in plain language instead of building reports by hand, and agencies can check client accounts faster.
It is hosted by Klaviyo, so there is nothing to install locally. What it can do depends on the permissions of the key or sign-in you give it, which is why the first decision is scope: reading reports needs far less access than creating or editing campaigns.
What it does
- Campaign and flow reporting
- Profile and segment lookups
- Drafting and managing campaigns, depending on permissions
Best for
Retention teams that want fast answers about flows and segments.
How to connect it
- Open Klaviyo's MCP server documentation and note the server address and authentication method for your AI tool.
- Create a private API key with only the scopes you need, starting with read access.
- Add the Klaviyo server to your AI tool's MCP settings with that key.
- Ask a reporting question first, such as flow performance, before trying anything that creates or edits.
Exact commands and addresses change. Use the official documentation for the current steps.
Questions you can ask it
- Which flows produced the most revenue in the last 90 days and which ones declined?
- How many profiles are in my VIP segment and how has it grown this quarter?
- Compare open and click rates for the last five campaigns.
- List flows that have had no sends in the past 30 days.
What it cannot do
- It cannot fix poor data quality such as duplicate profiles or missing purchase events.
- It can only see what the key's scopes allow.
- It does not decide marketing strategy. Treat suggestions as input to review.
Staying safe
- Use a restricted key and keep write scopes off until you have a specific, supervised task.
- Profiles contain personal data. Check your privacy basis and avoid sharing outputs that include customer details.
- Never let an assistant send campaigns without a human review step.
Watch out for: Scope the API key. Give it read access first, add write access only for specific tasks.
Frequently asked questions

It is a hosted server from Klaviyo that lets an AI assistant read, and with the right permissions manage, Klaviyo data such as campaigns, flows, profiles and reports.
+Do I need a developer to set it up?

Only if you grant permissions that allow it, which we recommend against without a human approval step.
