AI agents call quality_qr_get to retrieve information from Quality QR without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though quality_qr_get only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access quality_qr_get gives an agent. Each links to the full case and the policy that stops it:

Get full details of a specific QR code by its ID. Use this when the user wants to inspect a particular QR code's configuration, check its destination URL, view its design settings, or see its current status. Returns all metadata including content, destination, design, scan limits, and timestamps.. It is categorised as a Read tool in the Quality QR MCP Server, which means it retrieves data without modifying state.
Register the Quality QR MCP server in PolicyLayer and add a rule for quality_qr_get: 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_get 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 quality_qr_get 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_get. 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_get 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.
