What it does
AI agents ask Paitify before they pay: instant approve/deny against your policies, human in the flow, and a tamper-evident audit trail of every decision. Rail-agnostic, MCP-native, works with Claude. Never moves your money.
Paitify is the MCP-native spend policy engine for AI agents, with cryptographically-signed, offline-verifiable approvals and a complete audit trail.
Paitify is the spend policy engine for autonomous AI agents. Define granular rules, authorize transactions in real time, and maintain a complete audit trail — without slowing your agents down. 90 seconds: watch an AI agent get auto-approved at $49 — and stopped at $600. Modern LLM agents browse, purchase, spin up infrastructure, and call paid APIs — often autonomously, 24/7. Without centralized spend controls, a single misconfigured agent can drain budgets, violate compliance policies, or transact with unauthorized merchants before anyone notices. Traditional payment controls were designed for humans. Paitify is built for machines — real-time decisions, policy as code, and machine-readable…from paitify.io

PreloopJan 2026 · preloop.ai · ▲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…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
