SolidWorks API MCP Server

TypeScript MCP server that provides search and lookup access to the SolidWorks API documentation corpus in this repository.

Features

• Full-text and keyword search over SolidWorks API docs.
• Interface/member lookup for methods, properties, and events.
• Enum value lookup from JSON or markdown sources.
• Related member and example discovery helpers.
• Stdio MCP JSON-RPC transport for local and Claude Desktop usage.

Runtime and Tooling

• Runtime: Bun + TypeScript
• MCP transport: stdio (stdin/stdout)
• Test framework: Vitest
• Type checking: TypeScript compiler (tsc)

This repository uses Bun-only JavaScript tooling:

• Install dependencies: bun install
• Run package scripts: bun run <script>
• Run one-off CLIs: bunx <tool>

Quick Start

1. Install dependencies:

bun install

2. Start the MCP server:

bun run start

Data Root Configuration

By default the server reads from:

<repo>/solidworks-api

You can override this with SW_API_DATA_ROOT.

PowerShell:

$env:SW_API_DATA_ROOT = "C:\path\to\solidworks-api"
bun run start

Claude Desktop Configuration

Add an MCP server entry to claude_desktop_config.json.

Windows example:

{
  "mcpServers": {
    "solidworks-api": {
      "command": "bun",
      "args": [
        "run",
        "C:\\path\\to\\solidworks-api-mcp\\server\\solidworks_mcp_server.ts"
      ]
    }
  }
}

Restart Claude Desktop after updating the config.
