Manual MCP Configuration

If you prefer manual setup, add to your ~/.claude/.mcp.json:

{
  "mcpServers": {
    "br-build": {
      "command": "node",
      "args": ["<path-to>/BnRClaudePlugin/plugins/br-build/dist/index.js"],
      "env": {
        "BR_BUILD_EXE": "C:/Program Files (x86)/BrAutomation/AS6/bin-en/BR.AS.Build.exe",
        "BR_PROJECTS_ROOT": "C:/Users/YourName/Projects"
      }

The server auto-detects B&R Automation Studio installation paths. Override with environment variables:

Variable	Description	Default

BR_BUILD_TIMEOUT_MS	Build timeout in milliseconds	300000 (5 minutes)
BR_EXCLUDED_DIRS	Comma-separated directories to exclude from scanning	node_modules,Temp,Binaries,.git

Auto-detection paths

The server checks these locations for BR.AS.Build.exe:

1. C:/Program Files (x86)/BrAutomation/AS6/bin-en/BR.AS.Build.exe
2. C:/Program Files/BrAutomation/AS6/bin-en/BR.AS.Build.exe
3. C:/BrAutomation/AS6/bin-en/BR.AS.Build.exe
4. Any AS* version directory under the above paths
