The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
boolean_models Combine CAD models ~55
Create a new model by union, difference, or intersection of two or more saved models.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | – |

| name | string | yes | – |
| operation | string | yes | – |
No output schema declared.
No examples provided.
create_model Create CAD model ~75
Create a separate new CAD model from a declarative parametric shape tree. Do not use this to modify an existing model; load it and call update_model instead. Supports primitives, extrusions, transforms, mesh input, and boolean operations.

Permanently delete one saved CAD model. Call list_models or load_model first to identify the exact modelId, and pass expectedRevision when available to avoid deleting a newer edit.
| Name | Type | Req | Description |
|---|---|---|---|
| expectedRevision | integer | – | Current revision from load_model; rejects stale edits instead of overwriting them |

Is the MCP CAD Studio server safe to use?
MCP CAD Studio scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the MCP CAD Studio server expose?
MCP CAD Studio exposes 13 tools: studio_ui, list_models, load_model, create_model, generate_model, and 8 more. Their descriptions and schemas cost roughly 966 tokens of context every time the server is loaded.
Is the MCP CAD Studio server still maintained?
MCP CAD Studio is still listed as active in the MCP registry. We last reached this channel on 5 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the MCP CAD Studio server under?
MCP CAD Studio declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
