What is SolidworksMCP-python CLAUDE.md?

A contributor guide for a Python server that connects coding agents to SolidWorks, a Windows computer-aided design program. It explains supported environments, commands, testing, code checks, and documentation work.

Use it to install the project, run the server, test with or without SolidWorks, check and format code, and build or inspect its documentation.

It gives contributors one place to find the correct setup and development commands. It also clarifies which work needs Windows and an installed SolidWorks program.

Token cost

What it costs to keep this loaded

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	$0.03712	$0.03712
Opus 5.5	$0.01485	$0.01485

Security

Grade B, and why

SolidworksMCP-python CLAUDE.md scanned grade B with 1 finding 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 1mo 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- A BOM on `~/.claude/settings.json` makes Claude Code silently drop **all**

How it starts

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SolidWorks MCP Server (Python)

This file is the quick orientation guide for contributors and coding agents.

Platform and Runtime

Primary runtime is Python 3.13+.
Real COM automation requires Windows + SolidWorks installed.
Cross-platform development is possible in mock/test mode.

Build and Development Commands

Use either micromamba environment commands or local virtualenv commands.

Preferred PowerShell workflow

# Show command help
.\dev-commands.ps1

# Full install in micromamba env
.\dev-commands.ps1 dev-install

# Fast test pass (no SolidWorks-required tests)
.\dev-commands.ps1 dev-test

# Full test run including real SolidWorks integration
.\dev-commands.ps1 dev-test-full

# Lint and format
.\dev-commands.ps1 dev-lint
.\dev-commands.ps1 dev-format

# Docs build/serve
.\dev-commands.ps1 dev-docs-build
.\dev-commands.ps1 dev-docs-strict
.\dev-commands.ps1 dev-docs-audit
.\dev-commands.ps1 dev-docs

Virtualenv direct workflow

python -m venv .venv
.\.venv\Scripts\python.exe -m pip install --upgrade pip setuptools wheel
.\.venv\Scripts\python.exe -m pip install -e ".[dev,test,docs]"

# Run server
.\.venv\Scripts\python.exe -m solidworks_mcp.server

# Lint/tests/docs
.\.venv\Scripts\python.exe -m ruff check src tests
.\.venv\Scripts\python.exe -m pytest tests -m "not solidworks_only"

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.
