MCP tools · 13 exposed · ~966 tokens

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.

Tool Tokens
boolean_models ~55

Create a new model by union, difference, or intersection of two or more saved models.

NameTypeReqDescription
colorstring
modelIdsarrayyes
namestringyes
operationstringyes

No output schema declared.

No examples provided.

create_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.

NameTypeReqDescription
colorstring
namestringyes
shapeyes

No output schema declared.

No examples provided.

delete_model ~88

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.

NameTypeReqDescription
expectedRevisionintegerCurrent revision from load_model; rejects stale edits instead of overwriting them
modelIdstringyesSaved model ID from list_models, load_model, or a prior tool result

No output schema declared.

No examples provided.

duplicate_model ~33

Create an editable copy of a saved CAD model.

NameTypeReqDescription

No output schema declared.

No examples provided.

export_model ~35

Export a saved CAD model as ASCII STL or OBJ data.

NameTypeReqDescription
formatstringyes
modelIdstringyes

No output schema declared.

No examples provided.

generate_model ~159

Generate a built-in parametric template: bracket, pipe, gear, enclosure, or bolt. To revise a previously generated model, pass its modelId and expectedRevision to regenerate it in place. Omit modelId only when the user wants a separate new model.

NameTypeReqDescription
colorstringColor for a new model, or optional replacement color when regenerating
expectedRevisionintegerCurrent revision from load_model; rejects stale edits instead of overwriting them

Import an STL or OBJ model from text or base64 data and save it in the studio.

NameTypeReqDescription
colorstring
datastringyes
encodingstring
formatstringyes
namestringyes

No output schema declared.

No examples provided.

list_models ~18

List the CAD models currently saved in this studio.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

load_model ~64

Load a saved CAD model, including the modelId, current revision, complete editable parametric definition, and render mesh. Call this before update_model or delete_model.

NameTypeReqDescription
modelIdstringyesSaved model ID from list_models, load_model, or a prior tool result

No output schema declared.

No examples provided.

studio_ui ~41

Open the interactive CAD Studio. Use this when the user asks to view or work with a model visually.

NameTypeReqDescription
modelIdstringModel to select initially

No output schema declared.

No examples provided.

transform_model ~91

Apply an incremental translation, Euler rotation in degrees, or scale to a CAD model.

NameTypeReqDescription
expectedRevisionintegerCurrent revision from load_model; rejects stale edits instead of overwriting them
modelIdstringyesSaved model ID from list_models, load_model, or a prior tool result
rotationarray

No output schema declared.

No examples provided.

update_model ~189

Modify an existing saved model in place while preserving its modelId. Use patches for small edits (example: replace /shape/size/0), or shape to replace the complete definition. Load the model first and pass its expectedRevision. Never call create_model merely to revise an existing model.

NameTypeReqDescription
colorstringOptional replacement six-digit hex color
expectedRevisionintegerCurrent revision from load_model; rejects stale edits instead of overwriting them
modelIdstringyesSaved model ID from list_models, load_model, or a prior tool result
namestringOptional replacement name
patchesarrayTargeted edits applied in order to the current model. Use add for a new field/array item, replace for an existing value, and remove for an optional field.
shapeOptional complete replacement shape; cannot be combined with patches

No output schema declared.

No examples provided.

validate_shape ~56

Preflight a complete parametric shape without saving it. Reports static polygon/mesh topology errors and warnings, then asks the CAD kernel to verify the solid. Use this before create_model or update_model for complex shapes.

NameTypeReqDescription
shapeyes

No output schema declared.

No examples provided.
