WHAT IT DOES

What show_roles does on Mcp Windows

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

RISK

Why show_roles is rated Low

This tool performs a read-only operation to display existing database roles. It has no side effects, does not execute arbitrary code, does not modify data, and does not trigger external operations. The blast radius of misuse is minimal—an AI agent could only access role metadata already present in the database. This is a classic Read category tool.

From the tool's definition Tool name 'show_roles' and description 'Show all roles in the database' indicate a query operation that retrieves role information from a MySQL database without modifying or deleting data.

RECOMMENDED RULE

The rule that runs show_roles safely

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

show_roles Allowed

show_roles 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": {
    "show_roles": {}
  }
}

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

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