Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.02964 |
| Opus 5.5 | $0.00020 | $0.01186 |
| Sonnet 5.5 | $0.00010 | $0.00593 |
| Haiku 4.5 | $0.00005 | $0.00296 |
Grade A, and why
solidworks-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SolidWorks MCP
A model is a short Python shape program plus the native solids it compiles to. Coordinates are mm: Y up, X width, Z depth. The compiler owns sketches, selections, native equations, checkpoints and saving.
Tools
| Tool | Use |
|---|---|
get_model_context |
Start here: active document, revision, parameters, bodies with exact extents. components=[names] or detail="full" adds component records, include_source=true the embedded program |
model_api_lookup |
Constructors, topics, examples; topic="all" once instead of many lookups; "templates" and "template:<name>" for vetted joints |
execute_model_code |
mode: analyze (draft, no SolidWorks), create, edit, revert |
compare_reference |
Model silhouette against a reference image, per orthographic view: draft before the build, source="native" before delivery |
measure_reference |
Extents of single elements in a reference image; color=[r,g,b] for an element inside the figure |
inspect_model |
Numbers from the built bodies: extents, fits (body_pairs), sections, printability=true |
observe_model |
Native views, close-ups (components), custom cameras |
export_model |
Checked SLDPRT, STEP, one STL per body, manifest |
wait_operation |
Collect an operation that answered RUNNING |
get_executor_status |
COM-free: busy or quarantined, server version, SolidWorks memory |
reconcile_session |
Only for a quarantined session (unknown outcome) |
get_request_status |
Receipt of an earlier mutation by its key |
expert_tools |
Everything outside the constructors: list, describe, call |
Tools that take document_path activate that part or open it when it is closed.
The revision of a saved part does not depend on how its path is spelled.
Draft first, build once
A native build takes minutes, a draft milliseconds.
get_model_context, thenmodel_api_lookup(topic="all")once. Itspitfallstopic lists behaviour that otherwise costs a probe part.*marks keyword-only arguments. Helpers and loops work with the injectedmodel; no imports.- Read the references as volumes and write the whole program with a few named
parameters. For a typical joint start from a template:
model_api_lookup("templates")lists them,"template:hinge"returns code that builds as written. Repeat a body withmodel.pattern, not a loop. execute_model_code(mode="analyze", code=..., draft_views=["front", "right"])returns the predicted extents of every body, silhouette images andwarnings. The interpreter allows 512 components, including consumed nodes, patterns, placements and Booleans. Checkcomponent_count,max_componentsandremaining_components;model_api_lookup(topic="limits")gives active limits. The 6.30.0rc1 fixture matrix passed on SOLIDWORKS 2026 SP2.1: 128/256/512 nodes across straight, curved, loft and lattice lifecycles. This covers the tested fixtures; inspect each new native model and heed memory warnings. Nested patterns also have an expanded-complexity warning and a separate draft point budget; shared arrays count once, transformed copies separately.- With reference images call
compare_reference(image_path, view, code=..., height_mm=...)per orthographic view: IoU, a table of left/right extents per height level with deviations in mm (worst first) and an overlay. Correct the reliable proportion mismatches. If a mismatch follows a documented draft limitation (estimated bodies or unsupported cuts), record it and verify it natively after building. Do not loosen tolerance to pass the draft; keep the agreed tolerance for the final native check. mode="create"with a new absolute .SLDPRT path. Read the returned Front/Right/Isometric views and the warnings.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

solidworks-mcp is a skill published in the GitHub repository czuryk/SolidworksMCP (7 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 2,964 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-18.

kernelcad-mcp
Load when kernelcad mcp is available and you need to inspect or edit a live model without re-running the full CLI on every change. The MCP server exposes dynamic introspection tools that operate on evaluated in-memory state.
kernelcad-features
Edge and face features — fillet, chamfer, shell, face refs through operations, holes, cutouts. Use when adding rounded edges, recesses, bolt patterns, or carved profiles to a kernelCAD model.
kernelcad-kinematic
Use when verifying whether a moving assembly is buildable — sampled-pose collision sweeps across joint ranges, IK reachability for end-effector targets, mounting-hole fastener consistency, and static-load capacity on cantilever-shaped parts. Loads alongside kernelcad-authoring to gate design-time mechanism feasibility.
kernelcad-trace-from-image
Convert pixel-space features from a reference photo into normalized [0,1] waypoints, then into mm coordinates feedable to path().spline / path().nurbsSegment. Uses the tracefromimage MCP tool. Load when your blockout is in place and the next step is an organic-curve outline (eyewear brow, ergonomic handle, sneaker…
kernelcad-fields
Signed-distance fields — sdf.sphere/.box/.cylinder/.torus, sdf.smoothBlend, sdf.materialize. Use for smooth-blended primitives and organic shapes that BREP fillet cannot reach; result is a standard Shape.
kernelcad-sheet-metal
Folded sheet-metal parts — sheetMetal(profile, opts), .bend(edge, angle, radius), .flattenPattern(). Use when building L-brackets, U-channels, service panels, or any part fabricated from a flat blank + folds.
