## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why update_qr_code is rated Medium

This tool modifies existing QR code data within the instantKOM platform. While the change is reversible and does not involve deletion or destruction, it alters platform state. The blast radius is medium because unintended QR code modifications could redirect users to wrong endpoints or disrupt intended messaging flows, but the impact is limited to a single QR code resource and can be corrected.

From the tool's own definition: "Tool name 'update_qr_code' and description 'Update an existing QR code' indicate modification of existing data. The action is reversible (QR codes can be updated again or reverted)."

## Use case

AI agents use update_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.
