Most tools are clearly separated by domain: status monitoring, job history, file/model/gcode info, slicing, and live printer controls. A couple of pairs such as job_history/recent_logs and printer_status/snapshot could require careful descriptions to avoid misselection, but the names are mostly distinct.

All tool names use lowercase snake_case and follow a predictable split: noun-style names for queries and data lookups, and verb_noun names for actions like pause_print or set_temperature. This is a consistent and readable convention, even though it is not strictly verb_noun throughout.

Fifteen tools is at the high end of the ideal range but is well-justified for a 3D printer MCP covering monitoring, file inspection, slicing, print control, and temperature/fan adjustments. Each tool appears to cover a distinct function without redundant duplication.

The server covers monitoring, slicing preparation, and print lifecycle controls like pause/resume/cancel, but there is no obvious start_print or execute_slice_plan tool, leaving slice_plan as a dead end for automation. Catalog and model info are present, but upload/delete or direct print-from-catalog workflows are missing.
