MCP Gateway · Catalog
Klaviyo MCP server
OfficialKlaviyo MCP is the official Model Context Protocol server for Klaviyo, with OAuth and tools that let agents read campaigns, flows, lists, segments, and metrics, manage profiles and subscriptions, and pull campaign and flow reports. Connect it through the Speakeasy MCP Gateway and agents such as Claude, Cursor, and ChatGPT get one governed URL for it, with SSO, RBAC, and a full audit trail.

klaviyo_get_events

For aggregated data, prefer get_campaign_report or get_flow_report (performance metrics) or query_metric_aggregates (counts, sums, unique profiles). Only use this tool to inspect specific events or when the other tools don't support the dimension you need — in that case, only a small sample of events can be processed in context, so clearly tell the user the results are based on a limited sample.

klaviyo_query_metric_aggregates
Query and aggregate event data for a specific metric, with optional grouping by dimensions such as flows, campaigns, messages, etc. IMPORTANT: This endpoint returns data based on EVENT TIME (when events occurred), NOT send date. For campaign/flow performance data that matches the Klaviyo UI (which uses send date), use get_campaign_report or get_flow_report instead. Only use this tool when: - You need to aggregate raw event data by dimensions not supported by the Reporting API, but supported by this endpoint - You need time-series data broken down by hour/day/week/month - The Reporting API tools (get_campaign_report, get_flow_report) don't fulfill your specific requirements - You need to query custom metrics or non-standard aggregations Results from this endpoint are not directly comparable to get_campaign_report or get_flow_report due to different time semantics and uniqueness definitions (not attribution — both use the same attribution framework). If cross-referencing, clearly caveat this to the user. Examples of appropriate use cases: - Sum of revenue by flow over a time period (use sum_value measurement with $attributed_flow grouping) - Count of events per day/week/month for trend analysis - Unique profile counts grouped by campaign or message - Custom metric aggregations not available in standard reports
