Zovo Fishbone MCP

Zovo Fishbone turns a problem and its list of causes into a clean fishbone (Ishikawa) diagram. It supports up to 8 categories with up to 10 causes each and 5 sub-causes per cause, or uses the default 6M set. The tool performs layout checks to prevent label overlaps and generates PDF, SVG, CSV, and text outline downloads.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Fishbone draws a fishbone (Ishikawa, cause and effect) diagram from a problem and its categories of causes, with PDF, SVG, CSV and text outline downloads. Use make_fishbone to draw it and check_fishbone to review the cause list (counts, empty categories, duplicates, text over the limits, pages needed) without drawing. It does not find root causes by itself or rank causes. Files of large diagrams are kept for 1 hour so the download links work, then deleted.

make_fishbone — Make fishbone diagram
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a fishbone, Ishikawa or cause and effect diagram drawn for a problem, for example "make a fishbone for late deliveries" or "6M fishbone template for high scrap rate". Takes the problem (the effect), 2 to 8 categories with up to 10 causes each and up to 5 sub-causes per cause, and a landscape PDF page size. With no categories it uses the 6M set and says so. Returns counts per category, a layout check (overlapping labels, labels crossed by a bone), the PDF page count and smallest text size, an outline, an interactive diagram, and PDF, SVG, CSV and text downloads. Refuses text over the limits with the item named. Does not find, rank or verify root causes. Download links of large diagrams expire after about 1 hour.

check_fishbone — Check fishbone causes
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants their fishbone or cause and effect list reviewed before drawing, for example "check my fishbone causes for duplicates" or "how many pages will this Ishikawa diagram need". Takes the same problem and categories as make_fishbone. Returns counts per category, empty categories, duplicate causes (ignoring case), each text over its limit, other input problems, and the PDF pages needed on Letter, A4 and Tabloid. Draws nothing and makes no files. Does not judge whether a cause is a real root cause.
