WHAT IT DOES

What create_qr_code does on instantKOM MCP Server

AI agents use create_qr_code to create or update resources in instantKOM MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your instantKOM MCP Server environment.

RISK

Why create_qr_code is rated Medium

This tool creates a new QR code resource, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or cause destructive changes. The blast radius is minimal—a generated QR code can be replaced or regenerated without consequences. Severity is low because QR code generation is a non-privileged, isolated action with no side effects on sensitive data or system integrity.

From the tool's definition Tool name 'create_qr_code' and description 'Generate a new QR code for a channel' indicate creation of a new artifact within the instantKOM platform.

RECOMMENDED RULE

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

create_qr_code Rate-limited

create_qr_code stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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