Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Part dimensions, bolt patterns, hole sizes, fits and free STEP/STL CAD for real objects.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
get_part_dimensions_bolt_pattern_cadSTART HERE for one named object: returns its dimensions, mounting/bolt pattern, hole and thread sizes, ports, mating features with fit classes, and free STEP/STL links in a single call, plus up to five alternative matches. Use it whenever someone designs, prints or buys something
find_geometryBROWSE: list many matching objects, filtered by keyword, category, group, kind or release year, with paging. Use it when the user wants options or a list ('which M3 screws are there', 'all NEMA motors', '2023 phones', 'free files in Fasteners'), or to find a slug when the name is
find_by_dimensionsIdentify what an object is from one to four sizes you measured (an outline, a bore, a pin, a flange) when you do not know its name; use find_geometry when you do. Each size is compared, within tolerance_mm, against every object's overall size in any order and against its exact fe
get_geometryFULL RECORD for one object you already have the slug or exact name of (from a search or an alternative): its full sheet and mating features plus the basis of the numbers, every public CAD source with its license, related objects to traverse, FAQ, and paid-pack offers. Use it to c
get_free_filesFor importing a real part into CAD, 3D printing it, or modelling a mating bracket or enclosure around it. List the direct download URLs of one object's free STEP and STL files (and DXF where a 2D profile exists), with the license to credit. Use it when files are wanted rather tha
get_file_contentReturn the contents of one free file so the geometry can be read or modified directly: STEP and DXF as UTF-8 text, STL as base64. Units are millimetres, true size. Use it after get_free_files gives the file name and the content itself is needed; use get_free_files when a download
get_fitsFor designing a part that bolts to, clamps, slides over, presses into or otherwise mates with a real object (bracket holes, bore clearance, boss pocket, shaft fit). Return only the mating features of one object: each hole, pin, pocket, slot or socket that meets another part, with
list_categoriesReturn the whole category tree: every category, the groups inside it, object counts, and the catalog version. Use it to get the exact category and group spellings that find_geometry and find_by_dimensions filter on, or to see how the library is organised; it is the only tool that
request_objectFile a request for an object that is not in the library so it can be added; it is the only tool here that writes anything. Use it only after find_geometry and find_by_dimensions found nothing suitable; do not use it to ask questions or to request changes to existing objects. Each

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 9 days ago.
