AI agents use quality_qr_create to create or modify resources in Quality QR. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call quality_qr_create repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Quality QR.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a new trackable QR code saved to your Quality QR account. Use this when the user wants to generate a QR code for a URL, WiFi network, contact card, calendar event, phone number, email, SMS, restaurant menu, app download link, or social media profile. The QR code is persisted with scan tracking and analytics. Returns an inline SVG image of the QR code.. It is categorised as a Write tool in the Quality QR MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Quality QR MCP server in PolicyLayer and add a rule for quality_qr_create: 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 Quality QR. Nothing to install.
quality_qr_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the quality_qr_create 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 quality_qr_create. 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.
quality_qr_create is provided by the Quality QR MCP server (https://quality-qr.app/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
