Retrieve details of an existing QR code by its short ID. Returns the current target URL, metadata, and timestamps.
AI agents call get_qr_code to retrieve information from QR for Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
short_id | string | Yes | The short ID of the QR code to look up. |
Parameters from the server's own tool schema.

Attacks that exploit this kind of access
Retrieve details of an existing QR code by its short ID. Returns the current target URL, metadata, and timestamps. It is categorised as a Read tool in the QR for Agent MCP Server, which means it retrieves data without modifying state.
get_qr_code accepts 1 parameter: short_id. Required: short_id. The full parameter table on this page comes from the server's own tool schema.
Register the QR for Agent MCP server in PolicyLayer and add a rule for get_qr_code: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches QR for Agent. Nothing to install.
get_qr_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_qr_code rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_qr_code. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_qr_code is provided by the QR for Agent MCP server (qr-for-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
