What it does

A thin MCP server for GrowthBook that lets an assistant work with feature flags and experiments. It offers four tools: list skills, read a skill, a read-only API passthrough and a write API passthrough. Skill guidance is bundled at build time, and write calls are marked separately so clients can handle them with more care.

  2. 02Review the status of running experiments
  3. 03Read GrowthBook API data for a short report
