AI agents use qrcode_generate to create or update resources in Tools — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tools environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
size | number | — | Image size in pixels (default: 256, max: 1024) |

Parameters from the server's own tool schema.
This tool generates and returns QR code images as SVG data URIs. It is a content generation action that produces new data without destructive, executable, or financial side effects. No state is modified on the system beyond creation of the output.
From the tool's definition Tool name 'qrcode_generate' and description 'Generate QR code for text or URL. Returns SVG data URI' indicate creation of new data (QR code image).
Risk signalsAccepts raw HTML/template content (content)
Attacks that exploit this kind of access
Generate QR code for text or URL. Returns SVG data URI. It is categorised as a Write tool in the Tools MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
qrcode_generate accepts 5 parameters: size, bgColor, content, ecLevel, fgColor. Required: content. The full parameter table on this page comes from the server's own tool schema.
Register the Tools MCP server in PolicyLayer and add a rule for qrcode_generate: 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 Tools. Nothing to install.
qrcode_generate 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 qrcode_generate 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 qrcode_generate. 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.
qrcode_generate is provided by the Tools MCP server (https://www.jiebang.site/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
