How do I install the growthbook mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `GB_API_KEY`, `GB_API_URL`, `GB_SKILLS_ENABLED`, `GB_MCP_HOST`, `GB_MCP_URL`, `GB_HTTP_HEADER_CF_ACCESS_TOKEN` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
