Searches for available ROS 2 packages that match a given keyword.
AI agents call find_ros2_package to retrieve information from ROS MCP 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 search/lookup operation to discover ROS 2 packages. It retrieves information without modifying, executing, or deleting any data or systems. The operation is inherently non-destructive and carries minimal risk even if misused by an AI agent, as it only returns package metadata without triggering any robot control or system-level changes.
From the tool's definition Tool description states it 'Searches for available ROS 2 packages that match a given keyword' — a pure query operation with no side effects.
Documented attack patterns abuse exactly the kind of access find_ros2_package gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ROS MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for find_ros2_package:
{
"version": "1",
"default": "deny",
"tools": {
"find_ros2_package": {}
}
}find_ros2_package is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Searches for available ROS 2 packages that match a given keyword. It is categorised as a Read tool in the ROS MCP MCP Server, which means it retrieves data without modifying state.
Register the ROS MCP server in PolicyLayer and add a rule for find_ros2_package: 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 MCP. Nothing to install.
find_ros2_package 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 find_ros2_package 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 find_ros2_package. 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.
find_ros2_package is provided by the ROS MCP server (yutarop/ros-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
