WHAT IT DOES

What list_qr_codes does on instantKOM MCP Server

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

RISK

Why list_qr_codes is rated Low

This tool retrieves and queries QR codes from the instantKOM platform using filters, which is a non-destructive read operation. No data is modified, created, or deleted. The blast radius of misuse is minimal—an AI agent could only enumerate QR codes it has access to, posing no financial, destructive, or execution risk.

From the tool's definition Tool name 'list_qr_codes' and description 'List all QR codes with optional filters' indicate a retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs list_qr_codes safely

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

list_qr_codes Allowed

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

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

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