SolidWorks: MCP server, setup and security

What SolidWorks does

According to its repository: “Drive a running SolidWorks from an agent over COM: 86 tools for parametric parts and assemblies (extrude, revolve, sweep, loft, holes on any face, ribs, fillets, shells, patterns, mates, joints checked over their range, interference checks, STEP/STL export). Every modelling call returns measured vol”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. SolidWorks is listed under Design, art and accessibility, a category of 95 servers in the directory, where it ranks #58 by stars.

Topics declared by the repository: 3d-printing, ai-agents, cad, claude, parametric-modeling, pywin32.

Installing and connecting SolidWorks

Distribution modes declared in the official MCP registry:

• PyPI package (Python, started with uvx or pip)

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: Python. Listed systems: Windows.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to SolidWorks. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on June 25, 2026, the hjbaard/SolidWorks-MCP repository has 16 stars and 3 forks, with 0 open issues. It has more stars than 35% of the servers in the directory. It received changes this month. Version published in the registry: 0.16.1 (October 15, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
