VibeShift MCP

Hi HN, We are the devs behind VibeShift. We have been building this MCP server to put AI coding assistants in an automatic feedback loop. They code, test, debug, fix everything until we have a fully working, secure code. It tests like a real user, copies network/console and logical errors to give them back to cursor. (1 min demo - https://www.youtube.com/watch?v=bN_RgQGa8B0) We felt this was the natural next step for AI coding assistants. And with new asynchronous assistants like codex, having a plug & play tester makes sure you don't have to spend time debugging and…

VibeShift MCP launched on May 19, 2025 with 141 votes, #289 of 7,905 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.

What it does

Put cursor in auto feedback loop so that it tries to generate secure, fully working code in one shot. Completely open source.

[MCP Server] The Security Agent for AI assisted coding - GroundNG/VibeShift

VibeShift is an intelligent security agent designed to integrate seamlessly with AI coding assistants (like Cursor, GitHub Copilot, Claude Code, etc.). It acts as your automated security engineer, analyzing code generated by AI, identifying vulnerabilities, and facilitating AI-driven remediation before insecure code makes it to your codebase. It leverages the MCP (Model Context Protocol) for smooth interaction within your existing AI coding environment. The Problem: AI coding assistants accelerate development dramatically, but they can also generate code with subtle or overt security vulnerabilities. Manually reviewing all AI-generated code for security flaws is slow, error-prone, and…from github.com

    Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

    I built a wizard to turn ideas into AI coding agent-ready specsNov 2025 · vibescaffold.dev · ▲71

    I created vibescaffold.dev. It is a wizard-style AI tool that will guide you from idea → vision → tech spec → implementation plan. It will generate all the documents necessary for AI coding agents to understand & iteratively execute on your vision. How it works: - Step 1: Define your product vision and MVP - Step 2: AI helps create technical architecture and data models - Step 3: Generate a staged development plan - Step 4: Create an AGENTS.md for automated workflows I've used AI coding tools for awhile. Before this workflow (and now, this tool), I kept getting "close but not quite" results…

  • Tapflow 2.0▲1,125

    We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
