Maintenance

Recheck needed

The source snapshot needs another refresh before maintenance can be interpreted.

Popularity

Signals unavailable

No independently comparable adoption metric is currently stored.

Best for

Klaviyo teams that need analytics/marketing workflows in an AI client and can use read-only/user-content restrictions where appropriate.

Not ideal for

Teams handling sensitive marketing/customer data without clear API scopes or prompt-injection controls.

Avoid if

For exploratory use, prefer `read-only=true` and disable tools that expose user-generated content unless those features are specifically needed.

Trade-offs

Promoted after strict re-audit: canonical identity and MCP-native/publisher-backed implementation are sufficiently evidenced, with real workflow value, usable documentation, understandable permissions, plausible maintenance, and no unresolved security veto. Still not strong enough for Selected.

Evidence-backed setup

Install & Agents

Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.

Claude Code

Transport not recorded

Publisher documented

Connect via Streamable HTTP to `https://mcp.klaviyo.com/mcp`; complete Klaviyo OAuth / dynamic client registration and apply documented read-only/query restrictions when needed.

The publisher provides client-specific setup instructions.

Verify safely: Claude Code: `claude mcp list` and/or `/mcp` to confirm Connected; use any stronger vendor-documented smoke test where listed.

Uninstall and revoke

Claude Code: `claude mcp remove <name>`; also revoke OAuth/device/API credentials in the vendor account when the vendor provides such a control.

Evidence & methodology

Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

Reviewed access

Access & risk

Review the exact access boundary before connecting this MCP to accounts, credentials, or sensitive data.

Authentication: Hosted service uses OAuth/dynamic client registration; local server can use a scoped Klaviyo private API key.
Permissions: Permissions follow OAuth/API scopes. Hosted read-only mode disables write tools; UGC-related tools can also be disabled.
Data handling: Marketing/customer/account data and potentially user-generated content can be exposed to the AI client/provider. Klaviyo explicitly provides a control to disable UGC tools.
Cost: Klaviyo plan/API and model/provider costs apply.
Risk and cautions: Sensitive customer/marketing data, mutating campaign operations and prompt-injection risk from user-generated content require explicit controls.
