PTC-MCP Integration Server

Model Context Protocol (MCP) server for integrating PTC Windchill and Creo Parametric with LLM-based clients.

Overview

The PTC-MCP Integration Server provides a standardized gateway between MCP clients (ChatGPT Desktop, Claude Desktop, Agents SDK) and PTC's enterprise PLM and CAD systems. It enables natural language interaction with Windchill and Creo through structured, auditable workflows.

Features

MCP Protocol Support: Full implementation of Model Context Protocol
Windchill Integration: Read operations for parts, BOMs, and documents
Creo Automation: Model operations, exports, and parameter extraction
Security: Enterprise-grade authentication, authorization, and audit logging
Configuration: Centralized configuration management

Requirements

Node.js >= 18.0.0
TypeScript >= 5.3.0
Access to PTC Windchill (REST/OData API)
Creo Parametric with J-Link/OTK (for Creo automation)

Installation

# Install dependencies
npm install

# Build the project
npm run build

# Run in development mode
npm run dev

# Run production build
npm start

Configuration

Copy .env.example to .env and configure:

# Windchill Configuration
WINDCHILL_BASE_URL=https://your-windchill-server.com
WINDCHILL_USERNAME=service-account
WINDCHILL_PASSWORD=password

# Creo Configuration
CREO_JLINK_PATH=C:/Program Files/PTC/Creo X.X/Common Files/x86e_win64/obj/jlink
CREO_EXPORT_PATH=./exports

# MCP Server Configuration
MCP_SERVER_NAME=ptc-mcp-server
MCP_SERVER_VERSION=1.0.0
LOG_LEVEL=info

Usage

As MCP Server (stdio)

The server runs as an MCP server accessible via stdio:

node dist/index.js

MCP Client Configuration

Configure in your MCP client (e.g., Claude Desktop):

{
  "mcpServers": {
    "ptc-mcp": {
      "command": "node",
      "args": ["/path/to/ptc-mcp-integration-server/dist/index.js"]
    }
  }
}
