List all available ROS services.
AI agents call ros_list_services 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 enumerates ROS services without modifying, executing, or deleting any data or triggering external operations. It is a pure read operation for service discovery and introspection. The low severity reflects that misuse cannot directly harm systems—an LLM agent listing services poses minimal risk since it merely gathers information.
From the tool's definition Tool name 'ros_list_services' and description 'List all available ROS services' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available ROS services. 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_list_services: 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_list_services 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_list_services 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_list_services. 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_list_services 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.
