Show HN: Kinesis – Control your Mac with the Meta Neural Band

a couple hours ago i had astra take on a 10 month old repo of mine https://github.com/callbacked/neural-band-poc/ that involved finding a way to use the meta neural band independently from the glasses to read the sEMG data off of it. i really think it is a cool piece of technology that largely gets

Show HN: Authorize MCP tool calls without giving agents the credentials

Hey HN, Adam here. We built a small MCP example around a single problem: How do you let an agent use a tool that needs credentials without giving the credentials to the agent? The demo has two tools. One is open. One is protected. When the agent calls the protected tool, Keydris checks the policy fi

Show HN: Rebuno - An open-source runtime for production agents

I have been building Rebuno, an open-source execution runtime for operating AI agents in production. It manages execution state and guardrails across agents built with different frameworks. Agents run as HTTP services. Rebuno dispatches work through signed webhooks and keeps execution state in Postg

Show HN: Nari Qwen3-TTS and Qwen3-ASR – High accuracy, low latency and cost

Hey HN, Toby from Nari Labs here. We've been working on making OSS speech models super-fast. Last year, we built Dia, the first OSS text-to-speech model capable of doing natural dialogue. Since then, so many more great speech models have been released to the public. But the marke

Show HN: I built Otis, a minimal AI agent that runs local models out of the box

Hi everyone, Been working on Otis, an open-source ai agent that gives you one minimal experience across local and hosted open-weight models, privacy-focused by design. On setup it recommends a local model based on the hardware Otis is running on, downloads it and runs it through
