WHAT IT DOES

What stale_items does on Mcp Control Plane

AI agents call stale_items 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 stale_items is rated Low

This tool retrieves or lists expired/stale data items. It performs a read-only query operation with no side effects—it does not create, modify, delete, execute code, or involve financial transactions. The blast radius of misuse is minimal; returning stale data cannot directly harm the system. Low severity reflects the informational nature of the operation.

From the tool's definition Tool name 'stale_items' and description 'Return expired documents/facts' indicate a query or retrieval operation that fetches existing data without modification, creation, or deletion.

RECOMMENDED RULE

The rule that runs stale_items 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 stale_items, this is the rule to start with:

stale_items Allowed

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

policy.json

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

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 stale_items call is checked against it from then on.
