glc PromptGuard

What it does

glc PromptGuard is an eight-layer, multilingual prompt-injection defense for AI agents and RAG pipelines. It combines normalization, structural signals, framing awareness, intent classification, source-aware policy merging, a neural sensor, RAG/tool spotlighting, and an optional canary probe. Evaluated through millions of end-to-end runs built from several hundred thousand multilingual attack and benign examples. Available via remote MCP and REST, with 100 free credits for every account.

Host-side prompt injection gate for orchestrators on GLC MCP. Call before every LLM call — returns injection score and policy; optional session_id sticky…

CRITICAL: Call from your orchestrator BEFORE every main LLM call (never via model tool-choice). Evaluates intent × source context × impact — not keyword-only. Layered stack: normalize/multi-view → structural → discourse framing → intent → soft neural (attack + discourse + gated semantic) → policy floors; optional sticky session risk (session_id), spotlight/canary. Primary result: injection=true|false; also score, intent, policy, optional spotlight. context=user_prompt|rag_chunk|tool_result changes policy. Optional session_id enables multi-turn risk floor (same chat/run id each turn). Canary is a secondary tool-hijack probe only. Delta only — not full chat history. Not 100% security: host…from mcp.glc-rag.hu

  Every other gateway is detect-and-block. You don't get a security grade. You don't get red team in CI. We built the one that does. PromptGuard is a proxy: change your base URL (one line with our SDK, or a few lines without), and every request gets checked for prompt injection, PII leaks, jailbreaks, and abuse. 20+ threat vectors, 39+ PII types. We also ship a red team suite and an autonomous agent that mutates attacks to find bypasses - you get a grade (A-F) and a GitHub Action that runs these tests on every PR. So you see where you're weak before you ship. Works with OpenAI, Anthropic,…

  Clipto MCP▲655

  Hey 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…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
