WHAT IT DOES

What qr_generate does on ScorpTech x402 API

AI agents use qr_generate to create or update resources in ScorpTech x402 API, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScorpTech x402 API environment.

Parameter	Type	Required	Description
`bg`	string	—	Background hex, default ffffff
`fg`	string	—	Foreground hex, default 000000
`ecc`	string	—	L \| M (default) \| Q \| H
`size`	integer	—	Pixels per module 1-64, default 8
`text`	string	Yes	Text/URL to encode, 1-2953 bytes UTF-8
`format`	string	—	png (default) or svg
`margin`	integer	—	Quiet-zone modules 0-16, default 4

Parameters from the server's own tool schema.

RISK

Why qr_generate is rated Medium

An AI agent can call qr_generate faster than any human can review: one bad instruction and it creates or modifies resources in ScorpTech x402 API by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs qr_generate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For qr_generate, this is the rule to start with:

qr_generate Rate-limited

qr_generate stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every qr_generate call is checked against it from then on.

FAQ

Questions about qr_generate

What does the qr_generate tool do? +

Generate a QR code (PNG or SVG, base64 + data URI) for any UTF-8 text up to 2953 bytes. Options: ecc L|M|Q|H, size (px/module), margin, format png|svg, fg/bg hex colours. Price: $0.005 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/qr-generate. It is categorised as a Write tool in the ScorpTech x402 API MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does qr_generate accept? +

qr_generate accepts 7 parameters: bg, fg, ecc, size, text, format, margin. Required: text. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on qr_generate? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for qr_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 ScorpTech x402 API. Nothing to install.

What risk level is qr_generate? +

qr_generate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit qr_generate? +

Yes. Add a rate_limit block to the qr_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.

How do I block qr_generate completely? +

Set action: deny in the PolicyLayer policy for qr_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.

What MCP server provides qr_generate? +

qr_generate is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
