dsh-nx
Siemens NX 2512 inside DeepSeek Harness — run NXOpen journals in the open NX window from chat, and get an NX panel in the left sidebar.
English | 中文
What you get
- MCP tools (
mcp__nx__*, 15 of them):nx_live_ping,nx_live_status,nx_live_run_python,nx_live_module_list,nx_run_journal,nx_create_part,nx_open_part,nx_modeling_plan_template, … - Left-sidebar panel: bridge endpoint, tool list and copy-ready gear commands.
- Self-contained runtime: the MCP server (with NDJSON + Content-Length framing), the .NET live-bridge client and the NX menus ship in
vendor/; nothing else needs to be installed.
Requirements
| Item | Requirement |
|---|---|
| OS | Windows x64 |
| NX | Siemens NX / Designcenter 2512, installed and able to start |
| NX session | NX must be open before the tools are used; the bridge listens on 127.0.0.1:25121 |
| Python | Any of: the DSH bundled runtime (auto-detected), CODEX_PYTHON, or python on PATH |
Install
# 1) extract into a writable folder (do NOT install the .tgz directly:
# pnpm hard-links tarballs into a read-only store, and setup must write a file)
tar -xzf dsh-nx-0.1.0.tgz
dsh plugin --profile desktop add D:\tools\dsh-nx
# 2) resolve machine-specific absolute paths (once; rerun after moving the folder)
node D:\tools\dsh-nx\bin\setup.mjs
# optional: --project "D:\my\prj"
# 3) restart DeepSeek Harness
If NX is already running but the bridge is not up, run NX2512 Control > Start Codex Live Bridge in NX.
Use
Ask in chat:
Use
nx_live_pingto check the bridge.
Use
nx_live_run_pythonto runnx\gear_build.pywith{"m":20,"z":20,"b":200}.
gear_build.py (placed in <project>\nx\) accepts:
| Key | Meaning |
|---|---|
m / z / b |
module / teeth / face width |
alpha ha c rho x |
pressure angle and tooth-system factors (defaults 20 / 1 / 0.25 / 0.38 / 0) |
bore key_w key_t |
centre bore, key width, hub keyway depth (GB/T 1096) |
out_dir name |
output folder and part name |
Every build is verified numerically: volume (≤3 % from the analytic value), tip radius = da/2, face width = b, root-cylinder count = tooth count.
Example result for m=20, z=20, b=200 (GB/T 1356-2001 / GB/T 1357-2008):
d 400.000 db 375.877 da 440.000 df 350.000
volume 24,726,253 mm3 (analytic 24,522,114, +0.83 % from the root fillet)
faces: 60 parametric / 20 cylindrical / 2 planar
Uninstall
