Google Forms MCP

• 

  Form with %0+ Questions Takes 10+ minutes to Fill

• 

  Using this WEB MCP Extension i Made

• 

  Can Fill in 10 Seconds

Inspiration

Every day, millions waste hours filling repetitive Google Forms - surveys, job applications, registrations. Manual clicking through 50+ fields takes 5-10 minutes per form. We built an AI agent to do it in seconds.

What it does

Google Form Auto-Filler is an AI-powered agent using WebMCP that:

• Reads Google Form structure automatically
• Understands field types (text, email, select, checkbox, etc)
• Fills answers intelligently using Gemini AI
• Submits forms with one click
• Stores personal info locally (no server storage)

How we built it

1. Backend (Python Flask) - Secure API with Gemini integration, rate limiting, API key auth
2. Chrome Extension - Popup UI with local memory storage, DOM inspection
3. WebMCP Tools - Form analyzer, field filler, submission tracker
4. Security - Per-key rate limiting, JSON schema validation, safe parsing, CORS hardened

Tech: Python, Flask, React, Chrome Extension, Gemini API, WebMCP

Challenges we ran into

• Model output validation (JSON parsing robustness)
• URL validation & SSRF prevention
• Rate limiting per API key vs IP
• Handling different form field types dynamically
• Local storage privacy concerns

Accomplishments that we're proud of

1 . Production-grade security (9.5/10 audit score) 2.Fully functional Chrome extension with local memory 3.Safe model output parsing with schema validation

1. Per-key rate limiting for distributed deployments
2. Professional README with 20k+ character documentation 6.Built in 48 hours with zero shortcuts

What we learned

• WebMCP is powerful for browser automation
• Security-first development from day one pays off
• Local storage beats server storage for privacy
• Gemini AI handles unstructured form data better than structured APIs
• Extension development is simpler than we thought

What's next for Google Forms MCP

• Database persistence (SQLAlchemy)
• More field type support (file uploads, date pickers)
• Bulk form filling (CSV input)
• Smart response templates
• Analytics dashboard
• Support for Microsoft Forms, Jotform
