Get the TF frame tree structure.
AI agents call ros_get_frame_tree 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 performs a read-only query of the TF (transform) frame tree, which is a structural information retrieval operation. It does not modify parameters, delete data, execute arbitrary code, or commit financial operations. The 'Get' verb and retrieval-focused description confirm it is purely informational.
From the tool's definition Tool name 'ros_get_frame_tree' and description 'Get the TF frame tree structure' indicate a query operation that retrieves and returns information about the coordinate transform frame hierarchy without modifying any state.
Attacks that exploit this kind of access
Get the TF frame tree structure. 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_frame_tree: 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_frame_tree 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_frame_tree 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_frame_tree. 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_frame_tree 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.
