How to Use the GrowthBook MCP in Cursor

Q: Can Cursor create a GrowthBook feature flag while I write code?

Yes. You can ask Cursor to run createfeature directly from the chat or composer interface. It will generate the flag in your account and then write the code to use it.

Q: How does Cursor know which GrowthBook environments are active?

The agent calls listenvironments to pull the active list from your account. It uses this real-time data to suggest environment-specific targeting rules.

Q: Can I delete an old GrowthBook project from Cursor?

Yes, you can ask the agent to run deleteproject for outdated workspaces. It will ask for confirmation before executing the tool to prevent accidental deletion.

Q: How do I edit flag rules during a coding session?

Tell the agent what rules to change. It will use updatefeature to modify targeting or variations, saving you a trip to the browser dashboard.

Write code in Cursor that adapts to live GrowthBook feature flags and environment configurations in real time.

Generate code matching your GrowthBook flags

This MCP Server lets you query flag properties without leaving your editor. While editing in Cursor, your agent runs `get_feature` to read the exact schema of your flag, then writes the implementation code directly into your files. If a flag does not exist yet, you do not have to leave your editor. Tell Cursor to use `create_feature` to build it on the spot, and then write the corresponding React or Node.js block.

Direct environment sync inside Cursor

Keep your local development environments aligned with your remote setups. Cursor uses `list_environments` to find your target environments and can run `create_environment` if you are setting up a new pipeline. When you need to update targeting rules for a specific local setup, the agent uses `update_environment` to modify the configuration without breaking your active terminal sessions.

Project management via this MCP Server

This MCP Server handles the background API calls so you can structure your workspace without leaving your code editor. Cursor calls `list_projects` to fetch your team's active projects and uses `get_project` to pull metadata for your current working directory. If you are starting a new microservice, the agent can call `create_project` to register it in GrowthBook. It configures the workspace details so you can start adding flags immediately.

Setup guide

Set up GrowthBook MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the GrowthBook MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent GrowthBook transactions." If the MCP tools are loaded correctly, Cursor will call the GrowthBook tools automatically. You can also check Settings → MCP for a green status indicator.
