SEO is a nightmare. It’s a terrifying landscape of broken links, invisible meta tags, and cryptic Google algorithms.
For the Kiroween Hackathon, I decided to lean into that fear.
Meet RankBeacon SEO Exorcist. It’s a technical SEO analyzer that treats bugs like ghosts, 404s like zombies, and poor performance like a curse. But I didn't just want to make a "fun" toy; I wanted a tool that could actually fit into a serious developer's workflow.
Here is how I built a dual-mode React interface and integrated the Model Context Protocol (MCP) to let AI fix the issues for me.
💀 The Concept: UX Schizophrenia
Most dev tools are either "fun side projects" or "boring enterprise SaaS." I wanted both.
I built a Dual-Mode Interface that switches instantly with a hotkey (Ctrl+P):
Costume Mode: A VHS horror aesthetic with CRT scanlines. Issues are labeled as "Ghosts" (Critical), "Zombies" (Warnings) etc. The 'Haunting Score' shows how haunted your site is: 0 means perfect (no ghosts), 100 means extremely haunted. You see your current score (e.g., 65/100) and work to exorcise the demons to reach 0. In Professional Mode, it's inverted to 'SEO Health Score' where 100 is perfect.
Professional Mode: A clean, blue-and-white UI suitable for sending to a client without getting fired.
How we built the "Theme Engine"
Instead of just swapping CSS colors, we built a React context that swaps entire language dictionaries and component styles.
🤖 The Real Magic: MCP Integration
While the spooky UI is fun, the real technical innovation is under the hood. I integrated the Model Context Protocol (MCP).
If you aren't familiar with it, MCP is a standard that allows AI assistants (like Kiro, Claude, or IDE agents) to connect to external tools. By making RankBeacon an MCP server, I turned it from a website into a native skill for my AI.
Why does this matter?
Usually, checking SEO involves deploying your site, copying the URL, pasting it into a tool, and reading a report.
With RankBeacon's MCP integration, I can debug SEO inside my IDE while working on localhost.
Real-World Use Case: The "Fix It" Loop
Here is a real workflow I use with the tool:
The Prompt
I ask my IDE agent: "Analyze the SEO of http://localhost:3000"The Scan
The AI hits my local RankBeacon MCP server. It runs a headless browser scrape (using Playwright) in the background.The Result
Instead of a generic AI guess, it returns hard data from the tool.
Because the AI has context of my file system and the error report, I can just say: "Fix the meta description and add alt text to the hero image."
The AI opens app/layout.tsx, inserts the correct tag, and patches the image component. No tab switching required.
🛠 The Tech Stack
Frontend: React, Tailwind CSS (with a custom "Creepster" font configuration).
Backend: FastAPI (Python) for the analysis engine.
Protocol: MCP (Model Context Protocol) via a TypeScript/Docker server.
Crawling: Playwright for rendering JavaScript-heavy sites (SPAs).
Accessibility: We worked hard to ensure that despite the "glitch" visual effects, the site remains WCAG 2.1 AA compliant (Screen readers get the professional descriptions, not the spooky ones).
👻 Try It Yourself
RankBeacon SEO Exorcist is live. You can try the demo to see the "Dual Mode" switching in action, or check the repo to see how we handled the MCP implementation.
Live Demo: rankbeacon-exorcist.vercel.app
Fun Trick: Press Ctrl+P (or Cmd+P) on the site to toggle between "Business" and "Horror" modes instantly.
I’d love to hear what you think about combining gamification with serious dev tools. Does the "Halloween" theme make the tedious work of SEO more bearable? Let me know in the comments! 👇
