According to the README, it calls the GrowthBook REST API directly through a bundled Node helper script, without needing an MCP server. The skills cover creating, reviewing, publishing, targeting, ramping, and cleaning up feature flags, plus designing, launching, analyzing, and stopping experiments, along with read-only product analytics exploration. Setup requires a GrowthBook Personal Access Token or Secret Key, which the setup skill validates and stores locally with restricted file permissions. The README also states the plugin does not create metrics or datasources, does not generate SDK code, and does not support multi-armed bandit experiments.

About the service

GrowthBook is a warehouse-native platform that combines feature flag management, A/B test experimentation, and product analytics for engineering and product teams. Per the GrowthBook homepage, it is offered both as a hosted cloud service and as a self-hosted deployment, with SDKs for many languages and frameworks and a REST API that this plugin's skills call directly.

What you can do with growthbook

  • Run the gb-setup skill to configure and validate a GrowthBook API key and (for self-hosted setups) an API URL
  • Create, search, inspect, and archive/delete feature flags, including default values, metadata, and prerequisite flags
  • Manage the draft-review-publish lifecycle for flag revisions, including approvals, rebasing, and reverting
  • Add or edit targeting rules, scheduled activation windows, multi-step ramp schedules, and guardrail-monitored rollouts with auto-rollback
  • Design, launch, analyze, and stop A/B experiments, including SRM checks, lift/confidence-interval interpretation, and guardrail metrics
  • Search fact metrics and fact tables, and build ad-hoc charts through the product analytics explorer
