GrowthBook MCP Thin
A thin MCP server for GrowthBook with four tools:
| Tool | Purpose |
|---|---|
growthbook_list_skills |
List top-level skill entry points (name + description) |
growthbook_read_skill |
Return a listed skill or qualified child workflow (feature-flags or feature-flags/references/flag-create) |
growthbook_api_read |
Authenticated GET passthrough to the GrowthBook API |
growthbook_api_write |
Authenticated POST/PUT/PATCH/DELETE passthrough |
Competence lives in the skills repo and is bundled at build time. Capability is split into read vs write API tools (no per-endpoint formatters) so clients can honor readOnlyHint / destructiveHint correctly.
Tools are prefixed with growthbook_ so they stay unambiguous when a client has multiple MCP servers loaded.
Cursor plugin
Install GrowthBook from the Cursor Marketplace. The plugin connects Cursor to the hosted server at https://mcp.growthbook.io/mcp; the first tool call opens a GrowthBook sign-in to authorize it. Self-hosted GrowthBook users should configure the server manually as described below.
