ABB RobotStudio Bridge

Model Context Protocol server for ABB RobotStudio and ABB robot controllers.

Exposes 50 tools across two transports:

• rs_* — RobotStudio SDK tools, routed through a small RobotStudio Add-In (ClaudeBridge) that runs an HTTP listener inside the RobotStudio process. Used to inspect/edit stations, targets, paths, modules, variables, IO signals, controller config, and to drive the virtual controller simulation.
• rws_* — Robot Web Services (REST) tools that talk directly to a real or virtual ABB controller. Used for motors on/off, PP-to-main, start/stop program, IO read/write, file transfer, mastership, speed override, event log, etc.

Tested against IRC5 and OmniCore (CRB 15000 GoFa).

Install

git clone https://github.com/eliasbitsch/abb-robotstudio-mcp.git
cd abb-robotstudio-mcp
npm install
npm run build

Add-In (only needed for rs_* tools)

Build addin/ClaudeBridge.csproj against your RobotStudio SDK (RobotStudio 2024+), then:

./install-addin.ps1

This copies the compiled add-in into RobotStudio's add-in folder. On the next RobotStudio start, an HTTP listener comes up at http://localhost:58080.

Configure your MCP client

Example for Claude Code / Claude Desktop (mcp.json):

{
  "mcpServers": {
    "abb-robotstudio": {
      "command": "node",
      "args": ["C:/path/to/abb-robotstudio-mcp/dist/index.js"],
      "env": {
        "ABB_BRIDGE_URL": "http://localhost:58080",
        "ABB_RWS_URL": "http://localhost:80",
        "ABB_RWS_USER": "Default User",
        "ABB_RWS_PASS": "robotics"
      }
    }
  }
}

Env var	Default	Purpose
ABB_BRIDGE_URL	http://localhost:58080	RobotStudio Add-In HTTP listener
ABB_RWS_URL	http://localhost:80	Controller RWS endpoint (use the controller's IP for real robots)
ABB_RWS_USER	Default User	RWS user
ABB_RWS_PASS	robotics	RWS password

For a real GoFa, point ABB_RWS_URL at the controller (e.g. http://192.168.125.1) and supply real credentials.

Tools

RobotStudio SDK (rs_*, via Add-In)

rs_ping, rs_get_station, rs_save_station, rs_get_station_objects, rs_get_tasks, rs_get_paths, rs_get_path_targets, rs_create_target, rs_create_path, rs_get_position, rs_check_collisions, rs_get_modules, rs_read_module, rs_write_module, rs_read_variable, rs_write_variable, rs_read_config, rs_write_config, rs_get_io_signals, rs_controller_status, rs_start_simulation, rs_stop_simulation, rs_pause_simulation, rs_reset_simulation, rs_simulation_status, rs_set_sim_speed.

Robot Web Services (rws_*, REST)

rws_controller_status, rws_execution_state, rws_event_log, rws_get_tasks, rws_get_modules, rws_read_module, rws_write_module, rws_read_variable, rws_write_variable, rws_get_position, rws_get_io_signals, rws_read_io, rws_write_io, rws_set_motors, rws_reset_pp, rws_start_program, rws_stop_program, rws_get_speed_override, rws_set_speed_override, rws_request_mastership, rws_release_mastership, rws_list_files, rws_read_file, rws_write_file.

Safety

These tools can move real hardware (rws_set_motors, rws_start_program, rws_write_*). Only point ABB_RWS_URL at a real controller when you understand what an LLM with these tools can do, and prefer a virtual controller for development.
