## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `qr-code-reader` |
| Category | business-tools |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |
| Browser execution | Use the visible action or interactive controls. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | Not callable through HTTP. |
| Browser-agent interface | run_current_tool |

### Implementation notes

Decodes locally. A readable code is not proof that the embedded link is safe.

### Inputs and settings

No free-text input is required. Use the file inputs and/or settings below.

Accepted browser files: `image/*`. Choose one file.

No additional settings are declared for this tool.

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Local image/camera decode; display destination before any navigation.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

## Working with qr code reader

Business utilities help turn supplied details into a consistent document or calculation. Their usefulness depends on accurate names, dates, quantities and terms rather than the visual template alone.

## Common questions

### Does a generated document establish legal compliance?

A template cannot determine all requirements for every jurisdiction or transaction. Check the requirements relevant to the intended use before treating a generated document as final.

### Why should totals be checked separately?

Rounding, discounts and inclusive or exclusive taxes can affect the final amount. Make the calculation order and currency explicit.
