What is the GrowthBook MCP Server?
Connect your GrowthBook account to any AI agent to streamline your experimentation and feature management workflows through natural language.
What you can do
- Feature Management — List, create, and toggle feature flags across production and staging environments to control rollouts.
- Project Control — Organize your experimentation roadmap by managing projects, their descriptions, and specific settings.
- Environment Visibility — Audit and list all configured environments to ensure flags are deployed correctly across your stack.
- Full Lifecycle — Create, update, or delete projects and environments as your infrastructure and team needs evolve.
- Deep Inspection — Retrieve detailed metadata for specific features and projects to understand their current configuration and state.
How it works
- Subscribe to this server
- Enter your GrowthBook Secret Key
- Start managing flags and experiments from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Product Managers — quickly toggle features for beta testers or check the status of an experiment without opening the dashboard
- Engineering Teams — manage flags and environments directly from the code editor to maintain development flow
- DevOps Engineers — audit environment configurations and project structures via simple natural language queries

Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 15 tools from GrowthBook through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries GrowthBook, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Why teams choose Vinkius for GrowthBook in OpenAI Agents SDK
The GrowthBook MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 15 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
GrowthBook for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the GrowthBook MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I enable or disable a feature flag using the AI?
Yes! You can use the toggle_feature tool to change the state of any flag. Simply specify the feature ID and the target environment.
How do I see which environments are available for my flags?
You can use the list_environments tool. It will retrieve all configured environments like production, staging, or development used in your GrowthBook account.
Is it possible to create a new project to group my experiments?
Absolutely. Use the create_project tool by providing a name and optional description. This helps keep your feature flags and experiments organized by team or application.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
