Field notes

Hexum operates as an MCP server between a coding agent and its repository rather than as a separate editor or command-line tool. Its example narrows 41 files to 6 and reduces a turn from 18.2k tokens to 3.1k. The second operation reads architecture.hexum and applies a deterministic rule, with the displayed no_ui_to_data failure directing the agent toward services. The homepage names Cursor, Claude, and Antigravity as connection targets and says token counts are returned on each call.
