Profile

I was looking for a way to add AI agents to multiple systems that I maintain.I had a few requirements:- I work in multiple programming languages, so it needs to work for all of them.- I can control how tools access my system.- I can override the agent loop to try different patterns.- I can iterate on the loop without handling durability, streaming, and the rest of the nitty gritty.- I can iterate locally before deploying.- I can self host.Nothing existed that worked across programming languages, so I built it.It's not an SDK. It's a server that handles durability, streaming, MCP connections, LLM calls and connecting to channels like Slack.You can override every single step of the agent loop

An agent engine with no SDK, just TOML and webhooks is positioned in show hn launch, a segment that rewards a clear, focused offering.

It is recorded at the Show HN launch stage.
