## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `geojson-viewer` |
| Category | geo-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 |

### Inputs and settings

Text input: GeoJSON.

Example or placeholder shown in the interface (not a validated fixture):

```text
{"type":"FeatureCollection","features":[]}
```

Paste a valid GeoJSON object. Up to 1,000,000 characters. Review the settings before running.

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 geometry preview, validation and bbox; optional basemap network requests disclosed.

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

## How to use Geojson viewer

1. Enter geojson in the input field.
2. Review the settings, then choose Run Geojson viewer.
3. Review the result, then use Copy result or a download link when available.

## Working with geojson viewer

Geographic data uses coordinate order, units and reference systems to describe locations. Files that look similar can use different conventions, so a successful parse alone does not establish that points are in the right place.

## Common questions

### Why do points appear in the wrong country?

Swapped coordinate order, incompatible reference systems or wrong units can shift points dramatically. Test a location whose expected position is known.

### Does conversion improve location accuracy?

No. A format conversion preserves or transforms the supplied data; it does not make the original measurement more precise.
