Preloop▲121Hey HN, I’m Yannis, co-founder of Preloop. We’ve built a proxy for the Model Context Protocol (MCP) that lets you add human approval gates to your AI agents without changing your agent code. We’re building agents that use tools (Claude Desktop, Cursor, etc.), but we were terrified to give them write-access to sensitive systems (Stripe, Prod DBs, AWS). We didn't want to rewrite our agents to wrap every tool call in complex "ask_user" logic, especially since we use different agent runtimes. We built Preloop as a middleware layer. It acts as a standard MCP server proxy.You point your agent to…

Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

Prexist▲15Hey HN I built Prexist, an AI-powered tool that helps founders, PMs, and VCs quickly find out if their startup idea already exists, across 8 major platforms like Product Hunt, YC, GitHub, Crunchbase, and the App Stores. Until recently, running searches across all these platforms in parallel took ~60 seconds. We’ve just integrated Exa AI for search orchestration, and it’s now 3× faster while returning more relevant, semantically matched results. What it does: - Uses AI to understand your product idea and generate smart search queries - Searches 8 discovery and innovation platforms…
