WHAT IT DOES

What getColor does on Genkit MCP

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

RISK

Why getColor is rated Low

This tool retrieves a value (a random color) without creating, modifying, deleting, or executing any operations. It is a pure read operation with no blast radius if misused by an AI agent.

From the tool's definition Tool name is 'getColor' and description states it 'gets a random color' with no side effects or data modifications.

RECOMMENDED RULE

The rule that runs getColor safely

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

getColor Allowed

getColor 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": {
    "getColor": {}
  }
}

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

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