Growthbook

The GrowthBook MCP Server enables AI assistants to interact with GrowthBook, an open source feature flagging and experimentation platform. Create feature flags, set up A/B tests, analyze experiment results, and manage your experimentation workflow directly from your AI coding assistant.

Usage Examples

Ask Claude to:

1. Create a feature flag called new-checkout that defaults to false
2. Summarize my last 20 experiments
3. Create an A/B test comparing two checkout button colors - control with #007bff and variation with #28a745
4. Search the GrowthBook docs for how to set up a fact metric
