Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Dependencies

Dependency graphs from deps.dev; advisories from OSV.dev, including the GitHub Advisory Database and the PyPI Advisory Database; all CC BY 4.0. The graph is what a clean install of this version resolves today; nothing was installed or run. How it is checked.

Tools (5)

find_geometrySearch the Xem Studio library of real-object geometry (boards, devices, batteries, fans, fasteners, inserts, magnets, pipe, tri-clamp fittings, vintage forms). Returns summaries with overall size in mm, category, and whether files are free. Any argument may be omitted.
get_fitsMating features for one object: every hole, pin, pocket or socket that meets another part, with its exact size, what it mates with, the fit class (press, slide, run, socket, clamp, designed) and which files it applies to. All geometry on Xem Studio is exact with no printing tolerance; apply your process allowance to press / slide / run / socket features only and leave designed and clamp features as drawn.
get_free_filesList free STEP and STL downloads generated by Xem Studio from the standard for one hardware object (screws, nuts, washers, standoffs, inserts, dowels, magnets, pipe, tri-clamp parts, LM8UU). Returns direct URLs; CC BY 4.0; threads modeled as plain cylinders at major diameter.
get_geometryGet one object's dimension sheet (overall mm, mounting holes, notes, size table), the plain-text sheet, every public CAD source with its license, and Xem file offers (free STEP/STL URLs, or scan status and price). Accepts a slug, name or alias.
list_categoriesCategory and group tree with object counts.

Schemas: list_tools.
