AI QR Code Generator

ai_qr_code_generator_create_image

Create an AI QR code. Each QR code costs 0 credits.

MCP guidance:

  • This starts an async image generation job and returns id plus credits_charged immediately. If the user wants the finished result, call the wait_for_image_project helper with the returned id, or poll the matching GET /v1/image-projects/{id} endpoint until status is complete, error, or canceled. Completed projects include downloads with direct URLs. The custom wait helper also returns exact_download_urls separately from expiration metadata.

Input Schema

NameRequiredDescriptionDefault
nameNoGive your image a custom name for easy identification.Qr Code - dateTime
styleYes
contentYesThe content of the QR code.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesUnique ID of the image. Use it with the [Get image Project API](https://docs.magichour.ai/api-reference/image-projects/get-image-details) to fetch status and downloads.
credits_chargedYesThe amount of credits deducted from your account to generate the image. We charge credits right when the request is made. If an error occurred while generating the image(s), credits will be refunded and this field will be updated to include the refund.

A3.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the safety profile, and the description adds substantial behavioral context: it starts an async job, immediately returns id and credits_charged, describes terminal statuses, and explains how to retrieve completed downloads. No annotation contradiction is present.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core action and then provides necessary async workflow details. The MCP guidance is somewhat long but each sentence carries useful invocation or retrieval information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an async image-generation tool with an output schema and annotations, the description covers the important invocation and completion workflow. It does not discuss auth or rate limits, but those are not clearly required here.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 67%, and the description adds no additional parameter meaning beyond the schema. The schema already documents name, style.art_style, and content, so the description neither compensates significantly nor harms usability.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Create an AI QR code.' This clearly identifies the tool's purpose among many sibling image-generation tools, though it does not explicitly contrast itself with alternatives like ai_image_generator_create_image.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides workflow guidance for async completion: call wait_for_image_project or poll the image-projects endpoint. However, it does not explain when to choose this tool over other image-generation siblings, leaving selection guidance implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
