Etna

A tool server built for agentic harnesses. Etna gives you tool isolation out of the box — each kit is its own branch of the tool tree, independently toggleable per session. Drop a Python file in, and it's live.

Install

pip install etna-mcp
etna install

Adding a kit

etna install my_kit.py
etna install ntfy
etna install ntfy==1.0.0b1

.ekp packages

.ekp files bundle a kit and its skill documentation together. Install them the same way:

etna install my_package.ekp
