Execute a prepared software update. WARNING: This triggers actual software installation on the target system. Ensure the update has been prepared successfully first.
AI agents invoke ros2_medkit_execute_update to trigger actions in Ros2 Medkit. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Although software updates could be considered destructive in some contexts, the description emphasizes execution of a prepared update rather than irreversible data deletion. The tool triggers actual installation operations on a remote ROS 2 system, which fits the Execute category (runs code/operations whose effects depend on arguments).
From the tool's definition Tool name includes 'execute_update' and description states 'Execute a prepared software update' and 'triggers actual software installation on the target system.' This is a direct execution of external operations with real-world side effects.
Documented attack patterns abuse exactly the kind of access ros2_medkit_execute_update 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_execute_update:
{
"version": "1",
"default": "deny",
"tools": {
"ros2_medkit_execute_update": {
"limits": [
{
"counter": "ros2_medkit_execute_update_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}ros2_medkit_execute_update stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Execute a prepared software update. WARNING: This triggers actual software installation on the target system. Ensure the update has been prepared successfully first. It is categorised as a Execute tool in the Ros2 Medkit MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ros2 Medkit MCP server in PolicyLayer and add a rule for ros2_medkit_execute_update: 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_execute_update is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ros2_medkit_execute_update 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_execute_update. 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_execute_update 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.
