Update flags while coding in Cursor

Use `update_setting_value` to change flag behavior while you're writing code. The AI agent executes the change as you work. You won't have to break your flow to switch screens. It turns flag management into a standard part of your coding session.

Get flag status in Cursor

Call `get_setting_value` to see how a flag is currently set in your project. This gives you immediate insight into your active logic. It stops you from guessing about the current state of your features. You get the raw data injected right into your chat context.

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 ConfigCat 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.

Verify the connection

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

Common questions about ConfigCat MCP in Cursor

Create a .cursor/mcp.json file in your project root. Define the server command there so Cursor can trigger the tools during your coding session.

It works perfectly in agent mode. You can ask Cursor to adjust your feature flags while it generates code, ensuring your implementation matches your current settings.

You can use the `delete_setting` tool to remove flags you no longer need. The agent performs this action whenever you give the command.

If you commit the mcp.json file to your repository, everyone on your team gets access to the same tools. It keeps your development workflow consistent.

The server only accesses your feature flag configurations and environment metadata. No source code or sensitive user data is ever transmitted to the ConfigCat platform.
