fix(ci): unblock publish workflow on tests step The Publish (PyPI + MCP Registry) workflow failed at "Run tests" for v3.1.0: 1. tests/integration/test_quick_detect.py executed a live rosbridge connection at module level, so pytest's import-time collection hit sys.exit(1) with no rosbridge present, aborting the whole session (INTERNALERROR / "no tests ran"). 2. The publish job ran `pytest -m "not slow"`, which does not deselect the integration-marked tests, so they would attempt `docker compose up` inside the publish job. Fixes: - Guard test_quick_detect.py's body behind `if __name__ == "__main__"` so pytest imports it cleanly. Standalone usage and integration-tests.yml (which runs it as `python .../test_quick_detect.py`) are unchanged. - Publish workflows now run `pytest -m "not slow and not integration"`, so only unit tests gate publishing; integration tests remain in integration-tests.yml.

ROS MCP Server 🧠⇄🤖
ROS-MCP-Server connects large language models (such as Claude, GPT, and Gemini) to robots, enabling bidirectional communication with no changes to existing robot source code.
Why ROS-MCP?
- No robot source code changes → just add the
rosbridgenode to your existing ROS setup. - True two-way communication → LLMs can both control robots and observe everything happening on the Robot.
- Full context → publish & subscribe to topics, call services & actions, set parameters, read sensor data, and monitor robot state in real time.
- Deep ROS understanding → guides the LLM to discover available topics, services, actions, and their types (including custom ones) — enabling it to use them with the right syntax without manual configuration.
- Works with any MCP client → built on the open MCP standard, supporting Claude Code, Codex CLI, Gemini CLI, Claude Desktop, ChatGPT, Cursor, and more.
- Works across ROS versions → compatible across ROS 2 (Jazzy, Humble, and others) and ROS 1 distros.
🎥 Examples in Action
🏭 Example - AI Agent diagnosis of Industrial Robot End Effector (Video)
- The MCP server connects Claude to a production industrial robot, with only the technician manuals as reference.
- Claude discovers the robot's custom topic and service types and their syntax on its own.
- From a single prompt to test the gripper, it reads the manuals, runs its own tests, finds an anomaly, and reports the root cause.
🤖 Example - Controlling "Wilson" with natural language (video)
From a single prompt — "Grab a Coke from the fridge & go to the living room." — Google Gemini uses the MCP server to navigate and manipulate autonomously. Built on ROS 2 with Nav2 (SLAM) for mapping and navigation, and MoveIt to command the manipulator.
🐕 Example - Controlling Unitree Go2 in NVIDIA Isaac Sim (video)
The MCP server connects Claude to a simulated Unitree Go2 quadruped in NVIDIA Isaac Sim, interpreting natural language commands to navigate and control the robot.
