NX MCP Server

by kongbaic

Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
UGII_BASE_DIRNoThe Siemens NX installation directory. If not set, auto-detected from registry or PATH.
NX_MCP_WORKSPACENoThe workspace directory for NX files. Defaults to %USERPROFILE%\NX_MCP_WORKSPACE.
UGS_LICENSE_SERVERNoThe license server address. Defaults to 27800@localhost.27800@localhost
NX_MCP_ENABLE_JOURNALNoSet to '1' to enable Journal tools (requires NX_MCP_ENABLE_EXPERIMENTAL=1).0
NX_MCP_ENABLE_EXPERIMENTALNoSet to '1' to register experimental/legacy tools.0

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
nx_statusA

Report bridge, NX version, and active-part status.

nx_create_partC

Create a part inside the configured workspace.

nx_open_partC

Open a part from the configured workspace.

nx_save_partB

Save the active work part.

nx_close_partB

Close the active work part, optionally saving it first.

nx_export_stepB

Export the active work part as STEP inside the configured workspace.

nx_list_sketchesA

List sketches in the active work part.

nx_list_bodiesA

List bodies in the active work part.

nx_list_featuresA

List features in the active work part.

nx_list_edgesA

Inspect every edge of a body: index, curve type, endpoints, midpoint, length, bounding box, direction and adjacent face count. Read-only.

nx_list_facesA

Inspect every face of a body: index, tag, face type, centroid, area, normal (planar only) and adjacent edge count. Read-only.

nx_create_sketchC

Create and activate a sketch on a principal datum plane.

nx_sketch_lineB

Add a line to an explicit sketch reference.

nx_sketch_rectangleC

Add a rectangle to an explicit sketch reference.

nx_sketch_circleC

Add a circle (center + diameter) to an explicit sketch reference.

nx_sketch_arcA

Add an arc (center, radius, start/end degrees) to an explicit sketch reference.

nx_finish_sketchC

Deactivate and finish an explicit sketch reference.

nx_extrudeB

Extrude a sketch into a new body, or subtract it from an existing target body.

nx_holeC

Create a hole on a target body (circle sketch + boolean subtract).

nx_counterbore_holeA

Create a coaxial counterbore hole: a smaller deep through hole plus a larger shallow counterbore from the top face. Independent from nx_hole.

nx_countersink_holeA

Create a coaxial countersink (conical) hole: a smaller deep through cylinder plus a conical countersink from the top face. Independent of nx_hole / nx_counterbore_hole.

nx_shellA

Shell (hollow) a body: remove one face as an opening and keep a constant wall thickness. First version removes a single face; inward=True keeps the outer dimensions.

nx_edge_blendC

Create an edge blend (fillet) on edges of a body; default all edges.

nx_chamferB

Create a symmetric chamfer on edges of a body; default all edges.

nx_uniteA

Boolean-unite one or more tool bodies into the target body.

The target body keeps its id; the tool bodies are consumed and disappear from nx_list_bodies after the boolean.

nx_revolveA

Revolve a closed sketch section around an in-sketch 2D axis.

Creates a new solid only (no unite/subtract). axis_start and axis_end are sketch XY coordinates defining the revolution axis; angle is the sweep angle in degrees (0 < angle <= 360).

nx_mirrorA

Mirror a body about a datum plane.

plane selects the mirror datum plane (XY/XZ/YZ); offset shifts that plane along its normal by the given mm value (default 0). The mirrored body is created as an independent body and is NOT united with the source; use nx_unite if merging is required.

nx_linear_patternA

Pattern a body linearly along X/Y/Z.

count is the total number of instances including the original (count=4 yields 4 bodies); spacing is the per-instance delta in mm. The original body is kept and new instances are independent bodies (NOT united); use nx_unite if merging is required.

nx_circular_patternA

Pattern a body circularly about an axis through center.

count is the total number of instances including the original (count=4 yields 4 bodies); angle is the total sweep in degrees (360.0 distributes evenly around a full circle). The original body is kept and new instances are independent bodies (NOT united); use nx_unite if merging is required.

nx_undoB

Undo the last visible NX MCP operation.

nx_fit_viewA

Fit the active modeling view.

nx_releaseA

Gracefully stop the bridge and release the NX GUI for manual editing.

The current command completes, then the journal ends and NX becomes fully interactive (no restart of NX required). Start the bridge again later by running the launcher journal (Alt+F8) again.

TDQS

A3.5/5.0

Scored across 32 tools

Disambiguation5/5

Every tool targets a distinct operation: inspection, part management, sketch creation, sketch primitives, feature creation, boolean, patterns, and control. The three hole tools are clearly differentiated by geometry type, and list tools each query a different entity. No two tools appear to do the same thing.

Naming Consistency5/5

All tools follow a consistent nx_verb_noun pattern using lower_snake_case, such as list_faces, create_sketch, extrude, and unite. The verbs are predictable and the naming style is uniform throughout the set, making the interface highly navigable.

Tool Count4/5

While 32 tools is above the typical 3-15 range, it is appropriate for a comprehensive CAD modeling server. Each tool serves a specific function spanning part lifecycle, inspection, sketching, feature creation, boolean operations, and patterning. The count is justified by the breadth of NX modeling capabilities.

Completeness4/5

The tool surface covers part lifecycle (create/open/save/close), inspection (list faces/edges/sketches/bodies/features), sketch creation with primitives, feature creation (extrude, revolve, holes, shell, blend, chamfer), boolean unite, patterns, mirror, export, and undo. Missing delete and edit-parameter operations can be worked around via undo and recreation, so no major dead ends.
