Hexum documentation

Hexum is an MCP server for coding agents. It sits next to Cursor, Claude, Antigravity, or any client that speaks MCP. You create a key at /app, paste a snippet, and the agent gets four tools.

What it does

Cuts tokens sent to the model, then checks architecture.hexum without calling a model.
