VLA-Diff-MCP
by zhywwyzh
Provides tools for querying ROS topic status, echoing recent topic messages, and reading ROS-related logs from a Docker container, enabling monitoring of ROS navigation and scene graph operations.
Provides tools for listing tmux sessions, capturing pane output, and sending commands to tmux sessions (creating them if needed), enabling monitoring and control of terminal-based processes.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@VLA-Diff-MCPWhat's the current frequency and latest message on /agent_prompt?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
VLA-Diff-MCP
VLA-Diff project operations MCP server (Phase 1 read-only + Phase 2 write operations).
Features
Provide stable tools to the Agent via the MCP protocol, replacing ad-hoc bash commands each time:
Phase 1: Read-only tools
Tool | Description | Run location |
| Query ROS topic frequency + latest message | Container |
| Read the latest n messages from a ROS topic | Container |
| Query key service process status | Host |
| List tmux sessions | Host |
| Capture tmux session pane output | Host |
| Read agent_run / scene_graph logs | Container |
Phase 2: Write operation tools
Tool | Description | Safety mechanism |
| Publish fake instructions to /agent_prompt (task_id: 0=VLA/1=TRACKING/2=other) | None (simulates LLM messages) |
| Send commands to a tmux session (auto-create if it does not exist, no kill-session) | None (operates per reuse rules) |
| Restart ego_planner etc. (kill first then start, run in background) | confirm=True explicit confirmation |
| Fallback for arbitrary shell commands in the container | No whitelist, use with caution |

Prerequisites
Docker container
ros_noetic_uss_navalready created (ROS-related tools depend on it)If not started, ROS tools return clear errors; tmux / process tools are unaffected
Extension directions
More restartable services: elastic-tracker, tracking_service etc. (add to
KNOWN_RESTARTas needed)Service configuration: migrate startup commands to YAML to avoid hardcoding them in code
