get_parameter
AI agents call get_parameter to retrieve information from ROS 2 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and parallel naming with other read-only introspection tools on this ROS 2 MCP server indicates a data retrieval operation. Parameters in ROS 2 are configuration values read from the parameter server. This tool retrieves existing parameter values without side effects.
From the tool's definition Tool name is 'get_parameter' with no description provided. Based on the name and context of sibling tools (get_nodes, get_node_info, get_bag_info, get_launch_parameters, get_lifecycle_state), this follows the pattern of introspection/query tools that retrieve…
Attacks that exploit this kind of access
get_parameter. It is categorised as a Read tool in the ROS 2 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ROS 2 MCP Server MCP server in PolicyLayer and add a rule for get_parameter: 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 ROS 2 MCP Server. Nothing to install.
get_parameter 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 get_parameter 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 get_parameter. 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.
get_parameter is provided by the ROS 2 MCP Server MCP server (ranch-hand-robotics/rde-mcp-ros-2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
