    We’re open-sourcing a simple way to add “canary tools” to AI agents via MCP honeypots. These are functions your agent should never call during normal operation. If a canary is invoked, you get a high-fidelity signal of prompt-injection, tool hijacking, or lateralization—no heuristics, no extra model calls. What it is: - Go framework exposing decoy tools over MCP that look legitimate (names/params/descriptions), return safe dummy output, and emit telemetry when invoked. - Runs alongside your real tools; ship events to stdout/webhook or your pipeline (Prometheus/Grafana,…

    I do fullstack dev for work and side projects and recently moved everything to a couple VPSs on hetzner. Great setup, low cost, but one thing kept bugging me, how do I know if something is down without manually sshing in all the time? I tried the grafana + prometheus stack but the configuration time and seeing it use more resources than my actual apps was rough. Tried some smaller solutions too but nothing felt right. So I said screw it and built exactly what I wanted. tori is a single go binary that runs on your server, reads host metrics from /proc and /sys, monitors containers…

    Uptrace is an open source APM that supports distributed tracing, metrics, and logs. You can use it to monitor applications and troubleshoot issues. The latest v1.6 release adds support for service graphs, Prometheus remote write, Grafana data source for Prometheus, annotations, and much more. The main feature in this release is the ability to use Uptrace as a Prometheus data source in Grafana. Uptrace uses the original Prometheus engine, so all Prometheus queries should be supported and you should be able to use existing Grafana dashboards with the Uptrace data source. You can learn more in…

    Hello HN, Lucas and Soheil here from Praxos (https://mypraxos.com/)! We’ve been working on an AI personal assistant for a while now, and today we're sharing about our new webhooks feature with you. You can now add webhooks and triggers by asking Praxos over text or voice to set them up for you. Webhooks listen for conditions that, when they happen, trigger another action. Webhooks can execute one time or be indefinite. They can execute any action currently supported by Praxos. They are implemented for email and calendar (Gmail, Outlook), Notion, Slack, Discord, Trello,…

    Hello HN! Deploying the next-generation of security telemetry technologies to production is hard, so I’m building Impulse, a fully automated XDR platform that leverages tools like Osquery and eBPF to provide real-time threat detection & integrity monitoring for servers and workstations. It detects malware from behavioural patterns rather than signatures and enables deeper visibility than legacy tools. Impulse agents can be deployed on any device or VM running Linux such as cloud VMs in VPC networks, VPS servers or personal workstations and IoTs. In terms architecture, it is organised around…

    News-Hook is a tool for setting up webhooks on any real-world, using just prompts. You can write prompts like: “Inform me when [movie] gets a Rotten Tomatoes score” “Tell me when [rumor] is confirmed or denied” “Alert me on any tariffs news between USA and Brazil” Here’s how it works: -You write a prompt saying what you want to be informed about. -You set up a webhook as always, with URL and payload. -Done. There is a full API in case you wanna do this programatically We got Swagger-UI open in case you wanna see Would love feedback, use cases I haven’t thought of, and critiques on design or…
