WHAT IT DOES

What get_sensor_state does on DG-MCP

AI agents call get_sensor_state to retrieve information from DG-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_sensor_state is rated Low

Even though get_sensor_state only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_sensor_state safely

PolicyLayer is an MCP gateway: it sits between your AI agents and DG-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_sensor_state, this is the rule to start with:

get_sensor_state Allowed

get_sensor_state is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_sensor_state": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect DG-MCP, apply this rule, and every get_sensor_state call is checked against it from then on.

How do I enforce a policy on get_sensor_state? +

Register the DG MCP server in PolicyLayer and add a rule for get_sensor_state: 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 DG-MCP. Nothing to install.

What risk level is get_sensor_state? +

get_sensor_state is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_sensor_state? +

Yes. Add a rate_limit block to the get_sensor_state 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 get_sensor_state completely? +

Set action: deny in the PolicyLayer policy for get_sensor_state. 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 get_sensor_state? +
