Klaviyo MCP
Report on and build Klaviyo email and SMS campaigns, flows, segments and profiles.
Officialby KlaviyoHosted or on your computerChecked October 18, 2026
Klaviyo's MCP server connects Claude to your Klaviyo account so it can pull campaign and flow performance, look up profiles and segments, and create campaigns, templates and other assets. The hosted server is the recommended option, and a local Python package that uses a private API key is also available.
Who it is for
- Ecommerce brands that use Klaviyo
- Email and SMS marketers
- Agencies running retention programs
Prompts to try
Once it is connected, ask in plain words. Claude decides when to use the server and asks before it changes anything important.
