Connect AI Agents to GrowthBook - GrowthBook Documentation

GrowthBook works directly inside your AI coding agent: Claude Code, Cursor, and others. There are two ways to connect, and they’re complementary:

MCP Server: a live set of tools your agent can call mid-conversation.
Agent Skills: installable workflows that run the full feature-flag and experiment lifecycle, with GrowthBook’s draft → review → publish guardrails built in. No server to run.

You can install both. Many teams reach for the MCP server for quick, conversational tasks and the skills for repeatable, end-to-end workflows.

Which should I use?

	MCP Server	Agent Skills
What it is	A server exposing GrowthBook tools to your agent	Markdown playbooks your agent follows step by step
Setup	Add an MCP server entry that runs `npx @growthbook/mcp`	Install the plugin (no running server)
Best for	Quick lookups and one-off actions while you code	Repeatable, multi-step lifecycle workflows
Lifecycle coverage	Core flag, experiment, and product analytics actions	The full flag and experimentation lifecycle: create, target, ramp, experiment, analyze, stop, and clean up
Governance	Direct API calls	Draft → review → publish, safe rollouts, and two-step deletes built into each skill
Where it runs	Any MCP-compatible host, including agents that can’t run shell commands	Agents that can run shell commands: Claude Code, Cursor, Codex, and other agentskills.io agents

Agent can’t run a terminal? Use the MCP serverThe Agent Skills work by having your agent run a local Node helper, so they only work in agents that can execute shell commands, such as Claude Code, Cursor, and Codex. The MCP server is launched by your agent host from a one-time config entry. That lets it work in MCP-compatible hosts that don’t give the agent a terminal, like Claude Desktop. If your agent can’t run shell commands, use the MCP server.

Not sure where to start?Start with Agent Skills if you want to run flags and experiments end-to-end from your agent. Add the MCP Server if you mostly want quick, conversational access while you code.
