Why ros2_medkit_set_configuration needs a policy

This tool creates or modifies configuration parameters in a ROS 2 system. While the action is reversible (a parameter can be changed again), it alters system configuration which could affect ROS 2 operations, sensor behavior, or robot safety. The high severity reflects the potential for an LLM to misconfigure critical system parameters.

From the tool's definition Tool name contains 'set_' prefix indicating modification; description states 'Set a configuration (parameter) value' which is a reversible modification of system state.

POLICY

How to control ros2_medkit_set_configuration

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_set_configuration:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ros2_medkit_set_configuration": {
      "limits": [
        {
          "counter": "ros2_medkit_set_configuration_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

ros2_medkit_set_configuration stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Ros2 Medkit — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about ros2_medkit_set_configuration

What does the ros2_medkit_set_configuration tool do? +

Set a configuration (parameter) value. Use ros2_medkit_list_configurations first to discover available parameters and their current values. It is categorised as a Write tool in the Ros2 Medkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on ros2_medkit_set_configuration? +

Register the Ros2 Medkit MCP server in PolicyLayer and add a rule for ros2_medkit_set_configuration: 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.

What risk level is ros2_medkit_set_configuration? +

ros2_medkit_set_configuration is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit ros2_medkit_set_configuration? +

Yes. Add a rate_limit block to the ros2_medkit_set_configuration 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.

How do I block ros2_medkit_set_configuration completely? +

Set action: deny in the PolicyLayer policy for ros2_medkit_set_configuration. 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.

What MCP server provides ros2_medkit_set_configuration? +

ros2_medkit_set_configuration 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.

Enforce policy on every Ros2 Medkit tool call.

Start from Ros2 Medkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
