Get detailed information about a ROS topic.
AI agents call ros_get_topic_info to retrieve information from ROS1 Noetic MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries topic information, which is a read-only operation with no side effects. It does not publish to topics, call services, execute code, delete data, or perform any destructive or financial actions. The blast radius of misuse is minimal—an agent could only learn information about the robotic system's communication structure, not manipulate it.
From the tool's definition Tool name 'ros_get_topic_info' and description 'Get detailed information about a ROS topic' indicate a query operation that retrieves metadata about topics without modifying or executing any operations.
Attacks that exploit this kind of access
Get detailed information about a ROS topic. It is categorised as a Read tool in the ROS1 Noetic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ROS1 Noetic MCP Server MCP server in PolicyLayer and add a rule for ros_get_topic_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ROS1 Noetic MCP Server. Nothing to install.
ros_get_topic_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ros_get_topic_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ros_get_topic_info. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ros_get_topic_info is provided by the ROS1 Noetic MCP Server MCP server (lopisan/ros-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
