# Creo J-Link MCP Server
Based on **J-Link (OTK Java Free)**, the MCP server enables AI agents to directly control PTC Creo Parametric 6.0+.
Unlike creoson-mcp, this project **directly connects to Creo via J-Link**, eliminating the need for the CREOSON middleware.
```
AI Agent ←─ MCP (stdio) ─→ creo-jlink-mcp ←─ J-Link API ─→ Creo 6.0+
```
## Quick Start
### 1. Copy J-Link JAR
Copy the JAR files from the Creo installation directory to `libs/`:
```
<Creo>\Common Files\text\java\pfc.jar → libs/pfc.jar
<Creo>\Common Files\text\java\cipjava.jar → libs/cipjava.jar
```
### 2. Build
```bash
gradlew.bat fatJar
```
### 3. Start
```bash
set CREO_HOME=C:\Program Files\PTC\Creo 6.0.0.0\Common Files
scripts\start-mcp.bat
```
### 4. Configure Claude Desktop
```json
{
"mcpServers": {
"creo-jlink": {
"command": "scripts/start-mcp.bat",
"cwd": "C:/path/to/creo-jlink-mcp",
"env": {
"CREO_HOME": "C:\\Program Files\\PTC\\Creo 6.0.0.0\\Common Files"
}
}
}
}
```
