[Other] Show HN: Open-source implementation of Stanford's self-learning agent framework We implemented Stanford&#x27;s Agentic Context Engineering paper which shows agents can improve their performance just by evolving their own context.<p>How it works: Agents execute tasks, reflect on what worked&#x2F;failed, and curate a &quot;playbook&quot; of strategies. All from execution feedback - no training data needed.<p>Happy to answer questions about the implementation or the research!

[Monitoring/Observability] Show HN: ServiceRadar – open-source Network Observability Platform ServiceRadar is an open-source platform for distributed, secure network management and observability, scaling to 100k+ devices. Born from frustration with complex traditional NMS tools like Zabbix, it bridges legacy (SNMP&#x2F;syslog) and modern (gNMI, OTLP) protocols for cloud-native environments.<p>We built ServiceRadar to simplify monitoring hybrid telecom networks, evolving it into a Kubernetes-native solution with Helm and Docker support. It uses mTLS with SPIFFE&#x2F;SPIRE, NATS JetStream for event streaming (90M+ EPS), and SRQL for intuitive queries. Integrated with OpenTelemetry, Prometheus, and CloudEvents, it fills the network visibility gap in CNCF’s application-focused observability stack.<p>We’re seeking early adopters to try our demo or deploy locally—no sign-up needed. Feedback on usability or contributions for new protocols would be awesome.<p>Quick Start: helm install serviceradar carverauto&#x2F;serviceradar or docker compose up -d<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;carverauto&#x2F;serviceradar" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;carverauto&#x2F;serviceradar</a> (please star!)<p>Docs: <a href="https:&#x2F;&#x2F;docs.serviceradar.cloud" rel="nofollow">https:&#x2F;&#x2F;docs.serviceradar.cloud</a><p>Join our Discord or use GitHub Issues to share thoughts.

[Other] Show HN: ASCII Automata ASCII AUTOMATA is a tool to analyze the visual connectivity of characters in textmode fonts. It works by scoring edge connectivity of each piece and finding the best matching neighbour piece. Every time it places a piece, it &quot;grows&quot; towards the edges it touches by placing a matching piece. The red heatmap shows how frequently each character is used, useful for analyzing the fonts.<p>I initially made it as a tool for myself. When I design textmode art fonts it is sometimes difficult to figure out if a specific character would actually be useful for drawing or not. I wanted a tool which would show how useful and versatile some character is, and how well it connects to all other pieces.<p>But, as it turned out, this tool produces unexpectedly beautiful emergent patterns, so I made it into a proper little toy-tool for anyone to play around with.<p>Sidenote: it was also a good opportunity to test a new method for constructing a responsive semi-complex UI.<p>I made a web component which renders text as SVG paths using hershey vector fonts. The SVG fills the parent element, and applies stroke after the stretching happens: so strings &quot;a&quot; and &quot;aaa&quot; take the same amount of space, while remaining legible because the stroke is independent of the text&#x27;s transformations. Thus, I never have problems with overflowing text in the UI!<p>The layout is made with a CSS grid. For example the sidebar is simply &lt;div style=&quot;--cols:8;--rows:41;&quot; class=&quot;sidebar grid&quot;&gt; and then each UI element gets a position and size &lt;vec-text style=&quot;--x:1;--y:19;--w:2;--h:1;&quot;&gt;Cell Width&lt;&#x2F;vec-text&gt; . As a result, the layout is easy to make, the sidebar itself can be any size or shape,all the UI elements stay exactly where I put them, and all text remains legible due to the stretchy, monolined vector font web component. It&#x27;s great!<p>The WHOLE UI layout is just 120 lines of HTML, and 40 lines of CSS (for around 90 UI elements)!<p>(it did take a while to fiddle with the coordinate numbers, but I&#x27;m working on a wysiwyg tool to make that easier too...)<p>[crossposted this comment from mastodon: <a href="https:&#x2F;&#x2F;typo.social&#x2F;@gdc&#x2F;115405978249292146" rel="nofollow">https:&#x2F;&#x2F;typo.social&#x2F;@gdc&#x2F;115405978249292146</a>]

[Other] Show HN: We packaged an MCP server inside Chromium Hey HN, we just shipped a browser with an inbuilt MCP server!<p>We&#x27;re a YC startup (S24) building BrowserOS — an open‑source Chromium fork. We&#x27;re a privacy‑first alternative to the new wave of AI browsers like Dia, Perplexity Comet. Since launching ~3 months ago, the #1 request has been to expose our browser as an MCP server.<p>-- Google beat us to launch with chrome-devtools-mcp (solid product btw), which lets you build&#x2F;debug web apps by connecting Chrome to coding assistants. But we wanted to take this a step further: we packaged the MCP server directly into our browser binary. That gives three advantages:<p>1. MCP server setup is super simple — no npx install, no starting Chrome with CDP flags, you just download the BrowserOS binary.<p>2. with our browser&#x27;s inbuilt MCP server, AI agents can interact using your logged‑in sessions (unlike chrome-devtools-mcp which starts a fresh headless instance each time)<p>3. our MCP server also exposes new APIs from Chromium&#x27;s C++ core to click, type, and draw bounding boxes on a webpage. Our APIs are also not CDP-based (Chrome Debug Protocol) and have robust anti-bot detection.<p>-- Few example use cases for BrowserOS-mcp are:<p>a) *Frontend development with Claude Code*: instead of screenshot‑pasting, claude-code gets WYSIWYG access. It can write code, take a screenshot, check console logs, and fix issues in one agentic sweep. Since it has your sessions, it can do QA stuff like &quot;test the auth flow with my Google Sign‑In.&quot; Here&#x27;s a video of claude-code using browserOS to improve the css styling with back-and-forth checking: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;vcSxzIIkg_0" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;vcSxzIIkg_0</a><p>b) *Use as an agentic browser:* You can install BrowserOS-mcp in claude-code or Claude Desktop and do things like form-filling, extraction, multi-step agentic tasks, etc. It honestly works better than Perplexity Comet! Here&#x27;s a video of claude-code opening top 5 hacker news posts and summarizing: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;rPFx_Btajj0" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;rPFx_Btajj0</a><p>-- *How we packaged MCP server inside Chromium binary*: We package the server as a Bun binary and expose MCP tools over HTTP instead of stdio (to support multiple sessions). And we have a BrowserOS controller installed as an extension at the application layer which the MCP server connects to over WebSocket to control the browser. Here&#x27;s a rough architecture diagram: <a href="https:&#x2F;&#x2F;dub.sh&#x2F;browseros-mcp-diag" rel="nofollow">https:&#x2F;&#x2F;dub.sh&#x2F;browseros-mcp-diag</a><p>-- *How to install and use it:* We put together a short guide here: <a href="https:&#x2F;&#x2F;git.new&#x2F;browseros-mcp" rel="nofollow">https:&#x2F;&#x2F;git.new&#x2F;browseros-mcp</a><p>Our vision is to reimagine the browser as an operating system for AI agents, and packaging an MCP server directly into it is a big unlock for that!<p>I&#x27;ll be hanging around all day, would love to get your feedback and answer any questions!
