Growthbook

GrowthBook is an open-source platform for feature flag management and experimentation (A/B testing) that now offers a Model Context Protocol (MCP) server for seamless integration with AI tools, agents, and developer environments. It enables development teams to automate tasks like feature flag creation, experiment setup, and environment or project management from popular tools like VS Code, Cursor, and Claude. GrowthBook is intended for software teams, data scientists, and AI agents that need robust experimentation, feature flagging, and product experimentation infrastructure within their development workflows.
