Security Notes
The server uses environment variables for sensitive API keys, which is good practice. It includes `child_process.exec` in the `generate_flag_types` tool to run `npx growthbook` commands. While the commands are hardcoded to specific `growthbook` CLI operations and pinned to `@latest`, executing arbitrary `npx` commands, especially if the `currentWorkingDirectory` parameter is controlled by untrusted input, presents a potential command injection risk if the `growthbook` CLI itself were compromised or misused. However, in the context of an MCP server used by an expert developer, this risk is mitigated by the expectation of responsible client-side handling of `currentWorkingDirectory` and the fixed nature of the commands.
