Control structure and cost on the same path.
Hexum is MCP for coding agents: smaller context and deterministic architecture gates. Connect once. Keep the editor.
What you notice
The agent still opens what it should. The model still has enough to ship a patch. You are not paying to reprint the repo every turn.
What you keep
Cursor, Claude, or Antigravity. Git. Your models. Hexum sits on that path.
