Show HN: MCP for the ChatGPT Ads API – Query ChatGPT Ads from Claude and Codex

I built a small MCP server for the ChatGPT Ads advertiser API, which OpenAI opened to the public a couple of weeks ago.It's read-only for now: accounts, campaigns, ad groups, ads and insights (11 tools in total). You can query campaigns from Claude, Codex, Cursor and so on in plain language. Writes ("actions") are next; I have two ideas here: - wrap them in a deterministic tool (json in/out) - add a human in the loop (maybe even a verification/consistency check step bet

Show HN: Cost.dev (YC W21) – making agents cost-aware and cheaper to call

We launched Infracost on HN five years ago (https://news.ycombinator.com/item?id=26064588) where our CLI generated cost estimates for infra-as-code, e.g. "this Terraform PR adds $400/mo". The idea was to shift cloud costs (FinOps) left, so engineers get visibility of costs before deployment and make better decisions.Earlier this year we started seeing agent traffic in our logs and it looked like coding agents were calling our CLI. But that CLI wasn't designed w

Ask HN: Is it feasible to run a model on device for complete privacy?

Tried Gemma, Qwen and a few others. Need vision and larger context windows for an application I am working on. Results were quite poor Gemma 4E2B probably the best of the ones I tired but still fell apart and keep hallucinating with ~5000 tokens. Cloud based models had no problems even even Gemini 3.1 Flash-Lite and GPT-5.4 mini do a lot better and a way faster.

Ask HN: My competitors have flawed products but I can't get traction

Problem: I constantly save Instagram Reels/TikToks about restaurants, events, pop-ups, and things to do, but I always forget about them because they get buried in my saves.Solution: I built Cork. You can send a Reel or Tiktok directly to Cork without even needing to leave the app, and Cork will automatically extract the info in the reel and save it in a map + calendar.However, I've been finding it hard to get traction while my competitors have gotten traction/funding. I strongly b

Show HN: I benchmarked LLM agents on fixing real-world security vulnerabilities

I built a benchmark with 20 real CVEs across 18 Python projects (Pillow, GitPython, yt-dlp, urllib3, etc). I've run it over 5 LLM agents (3 OpenAI, 2 poolside) and 3 different prompts (full advisory, locate, diagnose) with a total of 300 runs. The agents are tasked to fix security vulnerabilities in a sandboxed environment and they are scored against a hidden security tests from the maintainer's own fix.Best solve rate was 50%. On the other 50%, some fixes are sometimes coherent and pa

A wild idea: Abstract reality using ontology

# A Wild Idea: Abstract Reality with Ontology## Background Large language models (LLMs) debuted with GPT-3 back in June 2020. After roughly five to six years of development, I believe the technology is still in its infancy, with massive room for improvement. A major priority is building powerful models that run on fewer resources, especially capable models that can operate smoothly on CPUs.More crucially, the engineering ecosystem around LLMs is also at an early stage. Many unresolved challenges

Show HN: TabyAgent – A lighter and easier alternative to OpenClaw/Hermes

I created TabyAgent, a lighter and easier-to-use alternative to OpenClaw and Hermes.It runs exclusively within Docker without requiring host mounts and allows you to chat via Telegram.I’ve used both OpenClaw and Hermes in the past, but I decided to build this myself because of their instability and, in the case of OpenClaw, its heavy footprint and numerous bugs.It was intentionally designed to be simple, so it lacks the complex features found in OC or HA—such as support for various messengers, i
