Hexum trims the agent’s view of the codebase
An MCP service for coding agents that prunes repository context and checks architecture rules inside the editor workflow.
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.
