Show HN: Word Clouds as an LLM Tool – MCP/REST API

Hacker News - Mon, 03/09/2026 - 3:56am

I wanted to be able to ask an LLM to “create a word cloud on [topic]” — LLMs are great at research, less great at layout.

So I built a purpose-built layout engine. It runs in the browser, and I’ve also wrapped it in a small Go/Fiber server using @napi-rs/canvas to expose it as an MCP server and REST API — so any LLM tool can call it directly.

Instructions are at https://word-cloud.net/ai.html

Feedback welcome at https://github.com/pilotso11/word-cloud-net/

Show HN: Satellite imagery object detection using text prompts

Hacker News - Mon, 03/09/2026 - 3:52am

I built a browser-based tool for detecting objects in satellite imagery using vision-language models (VLMs). You draw a polygon on the map and enter a text prompt such as "swimming pools", "oil tanks", or "buses". The system scans the selected area tile-by-tile and returns detections projected back onto the map as GeoJSON.

Pipeline: select area and zoom level, split the region into mercantile tiles, run each tile with the prompt through a VLM, convert predicted bounding boxes to geographic coordinates (WGS84), and render the results back on the map.

It works reasonably well for distinct structures in a zero-shot setting. occluded objects are still better handled by specialized detectors like YOLO models.

There is a public demo and no login required. I am mainly interested in feedback on detection quality, performance tradeoffs between VLMs and specialized detectors, and potential real-world use cases.

Building a TikZ library for ML researchers

Hacker News - Mon, 03/09/2026 - 3:15am

Building a TikZ library for ML researchers — styles, macros, and layout. Tools to make figures like these without starting from scratch each time. Does anyone actually need this? Would love to hear if figure-making is a pain point for you.

Show HN: Sentinel – Open-source MCP security scanner (config, probe, container)

Hacker News - Mon, 03/09/2026 - 3:11am

sentinel is an open-source CLI + GitHub Action that scans MCP server configurations, live endpoints, and Docker containers for security misconfigurations. It runs 26 detection rules across 3 modules CFG (static config analysis), PRB (live probe), CTR (container inspection) — and outputs in terminal, JSON, SARIF, or HTML. It grew out of our work building Helixar, an AI-native endpoint and API security platform. We kept finding the same MCP misconfigs (no auth, wildcard CORS, plaintext secrets) and wanted a lightweight, composable scanner that CI pipelines could actually use.
