Is @park-sang-gwon/google-flow-mcp safe?
Unofficial MCP server that drives Google Flow (labs.google Veo / Nano Banana) through your own Chrome session — video & image generation plus Scene Builder (extend, jump to, download)
This server can change things — files, a browser, a database, or paid online services. Limit what it can reach.
Why: writes or deletes files; controls a web browser.
What it can do
- Starts other programs
- Writes or deletes files
- Reads files
- Controls a web browser
- Calls internet services
Tools it offers your AI (11):
- flow_connect
- flow_generate_image
- flow_generate_video
- flow_inspect
- flow_media_download
- flow_project_open
- flow_scene_add
- flow_scene_extend
- flow_scene_status
- flow_screenshot
- flow_status
How to use it safely
- ✓ It starts another program (often a browser for sign-in, or a bundled binary). Install it only from the official package.
- ✓ Point it at one project folder, never your home directory or a whole drive.
- ✓ Only give it the folders it needs; files it reads can end up in the AI’s context.
- ✓ Use a separate browser profile without your logged-in accounts.
- ✓ Content it fetches from the internet can carry prompt-injection instructions.
- ✓ Pin the version (below) so an update can't change what it does without you noticing.
Code patterns worth reviewing
Automated pattern matches in the published package. Some are expected for this kind of server, and some may be false positives — they are pointers for review, not confirmed vulnerabilities.
Command injection risk
The agent appears to pass input into a shell or command execution path.
dist/browser/chrome.js:1
Unsandboxed browser automation
Browser automation (Puppeteer/Playwright/Selenium) is used together with an unsandboxed evaluation or rendering pattern.
dist/flow/inspect.js:42
External content fed into the prompt without isolation
The agent pulls in outside content (web pages, emails, retrieved documents) and adds it to its prompt, with no visible marking of that content as untrusted data.
dist/flow/composer.js:249
