What list_changes does on Mcp Control Plane

AI agents call list_changes 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.

Why list_changes is rated Low

This tool retrieves historical change events without side effects. It is a query/list operation that reads from a durable state log, fitting the Read category. Low severity because querying change history poses minimal risk; an agent cannot misuse this to cause harm beyond potentially gaining visibility into system changes, which is typically informational.

From the tool's definition Tool name 'list_changes' and description 'List recent durable change events, optionally filtered by area/tag' indicate retrieval and querying of existing change event data with optional filtering. No modification, deletion, or execution capability is present.

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

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