WHAT IT DOES

What list_fast_memory does on ConnectWise API Gateway MCP Server

AI agents call list_fast_memory to retrieve information from ConnectWise API Gateway MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why list_fast_memory needs a policy

This tool performs a query/list operation to retrieve cached or saved queries from fast memory storage. It retrieves and displays information without creating, modifying, deleting, or executing anything. This is a straightforward read operation with minimal security impact—the worst case is disclosure of previously saved queries, which would be low severity.

From the tool's definition Tool name 'list_fast_memory' and description 'List queries saved in Fast Memory' indicate retrieval of stored data with no modification or side effects.

POLICY

How to control list_fast_memory

PolicyLayer is an MCP gateway — it sits between your AI agents and ConnectWise API Gateway MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_fast_memory:

policy.json

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

list_fast_memory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
