Show HN: Agentic Trust – Enterprise MCP Server Platform for Secure AI Agents https://bit.ly/3HQi7Hf

Show HN: Agentic Trust – Enterprise MCP Server Platform for Secure AI Agents Hey HN! We're building Agentic Trust, a unified platform that turns your code into production-ready MCP (Model Context Protocol) servers with built-in authentication, security, and observability. *The Problem:* As AI agents become more capable, they need secure ways to access tools and data. MCP (Anthropic's open protocol) is great for standardizing agent-to-tool communication, but deploying MCP servers in production is complex. You need authentication, rate limiting, audit logs, multi-tenancy, and more—all while ensuring your agents can't be exploited through prompt injection or other attacks. *Our Solution:* One endpoint (agentictrust.com) that handles all your MCP servers. You write the tool logic, we handle everything else: - OAuth 2.0 authentication with scoped permissions - Rate limiting and usage analytics - Audit trails for compliance - Automatic versioning and routing - Protection against prompt injection attacks *Technical Details:* We've also been working on OIDC-A (OpenID Connect for Agents), a proposal to extend OIDC for agent identity. It adds claims for agent attestation, delegation chains, and capabilities. This was recently featured by WorkOS's CEO at Identiverse. The idea is that agents should have verifiable identities just like users do. When an agent acts on behalf of a user, you need to track that delegation chain for security and compliance. *Why Now:* With Microsoft announcing MCP support in Windows 11 and OpenAI adopting the protocol, we're seeing explosive growth in MCP usage. But most implementations are insecure—exposed endpoints, no auth, vulnerable to attacks. We're fixing that. *Links:* - Platform: https://bit.ly/4lb30qf - OIDC-A Proposal: https://bit.ly/4kVDN3C - WorkOS article on our work: https://bit.ly/4kVDNk8 We're in early access and would love feedback from the HN community. What security concerns do you have about AI agents? How are you handling agent authentication today? https://bit.ly/4lb30qf June 19, 2025 at 12:42AM

Show HN: Unregistry – "docker push" directly to servers without a registry https://bit.ly/3ZE07Gb

Show HN: Unregistry – "docker push" directly to servers without a registry I got tired of the push-to-registry/pull-from-registry dance every time I needed to deploy a Docker image. In certain cases, using a full-fledged external (or even local) registry is annoying overhead. And if you think about it, there's already a form of registry present on any of your Docker-enabled hosts — the Docker's own image storage. So I built Unregistry [1] that exposes Docker's (containerd) image storage through a standard registry API. It adds a `docker pussh` command that pushes images directly to remote Docker daemons over SSH. It transfers only the missing layers, making it fast and efficient. docker pussh myapp:latest user@server Under the hood, it starts a temporary unregistry container on the remote host, pushes to it through an SSH tunnel, and cleans up when done. I've built it as a byproduct while working on Uncloud [2], a tool for deploying containers across a network of Docker hosts, and figured it'd be useful as a standalone project. Would love to hear your thoughts and use cases! [1]: https://bit.ly/3SXwHz2 [2]: https://bit.ly/3DjeZBY https://bit.ly/3SXwHz2 June 19, 2025 at 12:17AM

Show HN: I built a tool that automates social content for busy startup founders Hey HN, I’m Johann - founder of Jars Global, where we build and launch a lot of products. We've seen how valuable social content can be for early traction, but staying consistent and keeping good quality without wasting time or money has always been a challenge. So I built Outbrand. A tool that you can setup once by inputting your brand details and goals. Then you get a 30 day content schedule with graphics. You can integrate with social platforms so it runs on auto-pilot. Setup once, then get daily content easily. PS. Please roast it! Really want to improve it so it's extremely high quality content that founders can use for their products. https://bit.ly/3ZDvW1U June 18, 2025 at 04:22AM

Show HN: Lstr – A modern, interactive tree command written in Rust https://bit.ly/4k1cdAD

Show HN: Lstr – A modern, interactive tree command written in Rust Hi HN, (First time poster!) I'm the author of `lstr`. I've always loved the classic Linux `tree` command for its simplicity, but I often found myself wanting more modern features like interactivity and Git integration. So, I decided to build my own version in Rust with a philosophy of being fast, minimalist, and interactive. It was also an excuse to help learn more about Rust\! Here's a quick look at the interactive mode: https://bit.ly/4lbiHxC... I've just released v0.2.0 with some features I think this community might find useful: * **Interactive TUI Mode:** You can launch it with `lstr interactive`. It allows for keyboard-driven navigation, expanding/collapsing directories, and opening files in your default editor. * **Git Status Integration:** Using the `-G` flag, `lstr` will show the Git status of every file and directory right in the tree output. * **Shell Integration:** This is my favorite feature. In interactive mode, you can press `Ctrl+s` to quit and have `lstr` print the selected path to stdout. This lets you pipe it into other commands or use it as a visual `cd`. For example, you can add this function to your `.bashrc`/`.zshrc`: ```bash lcd() { local selected_path selected_path="$(lstr interactive -gG)" if [[ -n "$selected_path" && -d "$selected_path" ]]; then cd "$selected_path" fi } ``` Then just run `lcd` to visually pick a directory and jump to it. It also supports file-type icons (via Nerd Fonts), file sizes, permissions, and respects your `.gitignore`. The project is open-source and I would love to get your feedback.

Show HN: MSDL – A minimal description language and editor for system diagrams https://bit.ly/3HBcigW

Show HN: MSDL – A minimal description language and editor for system diagrams When I dug into systems theory, the thing I found missing early on was a good editor for diagrams while exploring or explaining systems. So I used Graphviz, and found myself typing boilerplate and constructions that I found cumbersome. The editor I envisioned would be close to natural language, with a minimal syntax and a clear, but flexible semantics. So I started building a DSL and an editor for myself, but soon found there was a lot to learn, and a lot of pitfalls to avoid. It grew, and I had to revisit my goals with this project. That was the moment I thought: let me give back to the community. I created a spec for the language I had in mind, Minimal Systemigram Description Language. And a browser based and wails based desktop editor. And a Github page. If you want to jump there right away: https://bit.ly/4e3wYKx... . There is extensive help in the editors. To check it and learn, I recreated diagrams from introductory books I read. This in turn made me update the spec and the editor again. Today I released it on Github in version 0.1.0 for you to assess. It has a Github pages version of the editor for immediate trial, the spec, the desktop editors and the library, all open source. Builds are there for Ubuntu, Mac and Windows, the latter via Github Runners, and I tested all of them on the systems I have (one of each :D). I am far from a good programmer, but I put a lot of love into it. I hope it shows in the details. If you are a systems practicioner, learner, teacher, or just interested, it might be something for you. Let me know what you think, good or bad. Happy to answer questions. https://bit.ly/3SVjoiC June 15, 2025 at 04:44PM

Show HN: Zeekstd – Rust Implementation of the ZSTD Seekable Format https://bit.ly/4l5M8RH

Show HN: Zeekstd – Rust Implementation of the ZSTD Seekable Format Hello, I would like to share a Rust implementation of the Zstandard seekable format I've been working on. Regular zstd compressed files consist of a single frame, meaning you have to start decompression at the beginning. The seekable format splits compressed data into a series of independent frames, each compressed individually, so that decompression of a section in the middle of an archive only requires zstd to decompress at most a frame's worth of extra data, instead of the entire archive. I started working with the seekable format because I wanted to resume downloads of big zstd compressed files that are decompressed and written to disk on the fly. At first I created and used bindings to the C functions that are available upstream[1], however, I stumbled over the first segfault rather quickly (it's now fixed) and found out that the functions only allow basic things. After looking closer at the upstream implementation, I noticed that is uses functions of the core API that are now deprecated and it doesn't allow access to low-level (de)compression contexts. To me it looks like a PoC/demo implementation that isn't maintained the same way as the zstd core API, probably that's also the reason it's in the contrib directory. My use-case seemed to require a complete rewrite of the seekable format, so I decided to implement it from scratch in Rust using bindings to the advanced zstd compression API, available from zstd 1.4.0. The result is a single dependency library crate[2], and a CLI crate[3] for the seekable format that feels similar to the regular zstd tool. Any feedback is highly appreciated!

Show HN: Personalized Wealth Management – Institutional Meets Consumer https://bit.ly/4kL0Uh4

Show HN: Personalized Wealth Management – Institutional Meets Consumer Problem: If you have less than $100k to invest, you get a robo-advisor that asks you 5 questions and dumps you into one of three cookie-cutter portfolios. If you have more than $100k, you get a human advisor who charges 1-1.5% annually to... basically do the same thing with a smile and calming voice attached. Meanwhile, institutional investors get custom strategies built around specific durations, target dates, tax situations and actual investment goals. Not because the math is harder—but because the economics only work at scale. Here's the thing: Both traditional advisors and robo-advisors maximize profit by minimizing choice and directing capital into the bias strategies that generate them additional margins. Both just tweak a risk slider and call it "personalization." But institutional-grade portfolio construction doesn't have to be exclusive to the wealthy. The road was paved by platforms like Plaid, brining API connectivity—platforms and asset aggregation into the mainstream. Modern AI completes the picture by making true personalization economically viable via "micro-advise". No asset transfers, no new custodians, just sophisticated strategies based on your financial goals executed where you already invest coupled with personalized financial planning & budgeting. Technical Solution: We've built our MVP wealth management platform that creates truly personalized portfolios by combining institutional capital market expectations stemming 30+ global asset classes. All available through low-fee publicly available ETFs. Our approach: - SEC licensed & compliant Registered Investment Advisor - Generates unlimited unique portfolio combinations optimized for risk, return & goal specifics. - Personalizes to individual goals, not generic risk buckets. - Learns and improves from every user interaction - Provides institutional-grade sophistication without human bottlenecks - Removes manager bias for in-house strategies - Uses a "glidepath" approach similar to the US retirement target-date structure to maximize achievement certainty of important life goals (down-payment, retirement, etc) - Seeks to bring elements of habit forming platforms (like Duolingo) into retail wealth. Business Model Innovation: -Non-custodial + AI architecture enables subscription pricing ($10/month) instead of AUM fees. Users keep control of assets while getting personalized institutional strategies. Research Validation: - Glidepath strategies delivered higher values in 76% of scenarios (T. Rowe Price) - Global diversification outperformed domestic-only in 96% of 3-year periods (Hübner) - Chance of success metrics for significant life goals like retirement & major milestones are measurably improved via behavioral advantages & sequence risk protection (T. Rowe Price). Early Results: -Alpha users report 90%+ cost reduction vs. traditional platforms with superior personalization. Institutional style portfolios achieving goal-specific optimization that would cost minimum 10x elsewhere. -Base model portfolios have outperformed comparable portfolios from existing market incumbent robo-platforms on both an absolute & risk adjusted basis in H1 2025. What's Different: This isn't another robo-advisor using basic mean reversion. It's personalization that helps you understands and discover your specific goals and adapts continuously. Think "personal wealth manager in your pocket" rather than "generic portfolio assignment." All that, in a consumer product platform designed to empower retail investors and keep them engaged. Next Steps: Currently in invite-only alpha at https://bit.ly/448dlMT. We focused early on the portfolio construction & delivery process and are now building out the consumer-facing aspects of the web application. Looking for feedback from the HN community on our approaches to financial personalization. https://bit.ly/4nhUuI2 June 15, 2025 at 11:58PM
