autoshop-mcp-server v1.2

MCP server for Inovance AutoShop engineering workflows.

This server is modeled after the TIA Portal Openness MCP workflow shape, but AutoShop does not expose a confirmed Openness-style public automation API. The implementation therefore focuses on safe, useful capabilities:

detect the currently open AutoShop window and active project
inspect AutoShop project files without modifying them
list and read LD/ST/FB blocks
extract CALL relationships, symbols, comments, and variable records
read the AutoShop AI instruction catalog
generate ST and ladder review artifacts for manual implementation
read, write, and monitor live PLC points over Modbus TCP

Tools

Orientation and current-project context:

autoshop_bootstrap
autoshop_detect_open_instances
autoshop_scan_active_project
autoshop_run_capability_self_test
autoshop_list_instruction_catalog

Project inspection:

autoshop_scan_project
autoshop_list_program_blocks
autoshop_read_block_source
autoshop_analyze_call_graph
autoshop_search_symbols
autoshop_parse_variable_tables

Generation and validation:

autoshop_validate_point_table
autoshop_generate_st_source
autoshop_generate_ladder
autoshop_scaffold_project_bundle

Live PLC access:

autoshop_read_live_points
autoshop_write_live_points
autoshop_monitor_live_points

Run

cd D:\mcp\autoshop-mcp
npm install
npm run build
npm start

Default transport is stdio. HTTP mode:

$env:TRANSPORT="http"
$env:PORT="3000"
npm start

MCP client config

{
  "mcpServers": {
    "autoshop": {
      "command": "node",
      "args": ["D:\\mcp\\autoshop-mcp\\dist\\index.js"],
      "cwd": "D:\\mcp\\autoshop-mcp"
    }
  }
}

Chinese user guide

See docs\autoshop-mcp-v1.2-user-guide.md for a Chinese setup and usage guide.

Recommended workflow

When AutoShop is already open:

Call autoshop_detect_open_instances.
Call autoshop_scan_active_project.
Call autoshop_analyze_call_graph.
Use autoshop_list_program_blocks, autoshop_read_block_source, autoshop_search_symbols, and autoshop_parse_variable_tables.

The core project tools can omit projectPath; they will use the active AutoShop window. autoshop_read_block_source can also omit blockName; it will read the active block shown in the AutoShop title bar.

Tested active project:

{
  "projectPath": "D:\\牧哲\\1、程序\\镜像\\抛光\\PLC\\111",
  "activeBlock": "MAIN",
  "plcIp": "192.168.250.3"
}

Ladder and ST

Use examples\ladder.start-stop.json as a start/stop rung example. The server returns an ASCII ladder diagram plus equivalent ST so the logic can be reviewed and recreated in AutoShop.

AutoShop .LD and .FB files are proprietary binary containers. The project tools extract readable calls, instructions, comments, and symbols, but they do not claim lossless native LAD import/export.

Safety

Project inspection tools are read-only. Live write operations require confirmRisk=true.
