WHAT IT DOES

What states does on Mcp Control Plane

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

RISK

Why states is rated Low

This tool retrieves or queries data (state information) with no side effects. It is a pure read operation, consistent with Home Assistant's entity state retrieval pattern. No data is created, modified, deleted, or executed.

From the tool's definition Tool name 'states' and description 'Return all states, or a single entity state when entity_id is provided' indicates a read-only query operation that retrieves state information without modifying, executing, or deleting anything.

RECOMMENDED RULE

The rule that runs states safely

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

states Allowed

states 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": {
    "states": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every states call is checked against it from then on.

FAQ

Questions about states

What does the states tool do? +

Return all states, or a single entity state when entity_id is provided. It is categorised as a Read tool in the Mcp Control Plane MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on states? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for states: 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 Mcp Control Plane. Nothing to install.

What risk level is states? +

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

Can I rate-limit states? +

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

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

states is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
