⚙️ Installation

Follow the installation guide for step-by-step instructions:

🧭 DDS discovery warm-up (Docker)

If the first tool call returns an incomplete list of topics/services right after container start, DDS discovery may still be in progress. The server performs a one-time warm-up on the first tool call in container environments; tune it via:

MCP_ROS_DISCOVERY_STABLE_SEC (default: 1.0)
MCP_ROS_DISCOVERY_TIMEOUT_SEC (default: 5.0)
MCP_ROS_DISCOVERY_WARMUP=false to disable

💡 Want to try it in simulation?

🐞 Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with this command:

bash

npx @modelcontextprotocol/inspector uv --directory /path/to/ros2_mcp run mcp_ros_2_server

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.

📚 Origins and evolution

We built this server to make AI‑assisted ROS 2 development fast and reliable. Internally, we needed a simple way for agents to discover message types, publish/subscribe to topics, and call services—without boilerplate or flaky networking. That led to a few core design goals:

Handle all ROS 2 message types (including nested fields) so agents can write and test any code
Integrate topic pub/sub and service calls to validate behavior end‑to‑end
Work seamlessly with GitHub Copilot in VS Code and other MCP clients
Use a simple stdio transport to avoid network complexity

After dogfooding it, we open‑sourced the project to help the broader ROS 2 community build faster with AI. It’s now useful not only for development, but also for controlling robots, running QoS experiments, and analyzing live data and robot/swarm state. The project is actively maintained—features and improvements ship regularly based on user feedback. If this project helps you, please star the repo and share your use case!
