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:

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