I shipped mcp-probe — a CLI that points at any MCP server, enumerates every tool, resource, and prompt, calls each with auto-generated arguments, validates against declared schemas, prints a pass/fail scorecard, and exits 0/1 for CI. The plan for launch week: run it against the official Node MCP servers and post results. The first run made me look like I'd broken half the ecosystem. The second, af
This technical post walks through the design and implementation of Secure Playground: a local web app that simulates prompt-injection attacks against large language models and demonstrates simple defenses. Provide a minimal, reproducible environment to test payloads and defensive strategies. Make it easy to add new providers and run mutation-based red-team experiments. Offer a leaderboard and scor
Japanese subscription services have a problem with terms and conditions. Not the length — that's universal. The specific issue is that Japanese cancellation terms, automatic renewal clauses, and price change notifications are buried in dense legal Japanese that's difficult to parse even for native speakers. The phrasing is designed to be compliant, not readable. I've been surprised by charges I di
A 16-pixel hero in your macOS menu bar. Watches LLM traffic. That's it. You remember RunCat — the kitten in your menu bar that runs faster when your CPU is busy. Almost a decade old. Adorable. Useful. Asks nothing of you. AI-native development needs the same thing for a different signal. Not CPU. Agent traffic. Is there a live LLM request flowing right now, or is everything quiet? That's why I bui

This is Part 1 of a two-part series. Part 2 (coming soon): Connecting to spoke clusters from a controller using multicluster-runtime, driven by ClusterProfile. The Cluster Inventory API (multicluster.x-k8s.io) is driven by SIG-Multicluster and centered on the ClusterProfile resource. It only delivers value when something produces those ClusterProfiles. That something is a cluster manager. Today, t
When developers travel, we usually prepare the obvious things. Laptop charger. But there is one dependency that is easy to underestimate until it breaks: mobile internet. A trip to China makes this especially obvious. Not because China is hard to travel in, but because so many basic interactions are mobile-first: navigation, translation, ride-hailing, hotel communication, ticket confirmations, pay
A defaced website is a curious problem. It's loud — anyone visiting the page can see something is wrong. But it's also quiet from a server's perspective: HTTP returns 200, your uptime monitor is happy, your TLS cert hasn't moved, and the CMS logs show a "successful" content update from a legitimate-looking session. The signal is on the rendered page, not in the metrics. I run a site at hi3ris.blue
