AI agents call ros2_medkit_get_trigger to retrieve information from Ros2 Medkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a trigger configuration or state without modifying, executing, or deleting anything. It is a simple lookup operation typical of discovery and inspection functionality in the ROS 2 medkit system. The low blast radius reflects that misuse would only expose information rather than cause operational changes or damage.
From the tool's definition Tool name 'get_trigger' and description 'Get details of a specific trigger by ID' indicate a retrieval operation with no side effects. The verb 'Get' and the context of querying trigger details by identifier are characteristic of read-only data retrieval.
Documented attack patterns abuse exactly the kind of access ros2_medkit_get_trigger gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ros2 Medkit, and nothing reaches the server without passing your rules. This is the rule we recommend for ros2_medkit_get_trigger:
{
"version": "1",
"default": "deny",
"tools": {
"ros2_medkit_get_trigger": {}
}
}ros2_medkit_get_trigger is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get details of a specific trigger by ID. It is categorised as a Read tool in the Ros2 Medkit MCP Server, which means it retrieves data without modifying state.
Register the Ros2 Medkit MCP server in PolicyLayer and add a rule for ros2_medkit_get_trigger: 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 Ros2 Medkit. Nothing to install.
ros2_medkit_get_trigger 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 ros2_medkit_get_trigger 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 ros2_medkit_get_trigger. 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.
ros2_medkit_get_trigger is provided by the Ros2 Medkit MCP server (selfpatch/ros2_medkit_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ros2 Medkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
