## Description

Search for features in a layer where a field matches a value. Builds a `WHERE field = 'value'` query with SQL-escaped single quotes. Returns matching features as a flat array of attribute objects (no geometries). [See the documentation](https://developers.arcgis.com/rest/services-reference/enterprise/query-feature-service-layer-.htm)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `featureService` | `string` | Yes | The Feature Service to use: a 32-character portal item ID (e.g. "0123456789abcdef0123456789abcdef"), a full FeatureServer URL (e.g. "https://services.arcgis.com/.../FeatureServer/0"), or a service title that matches search results Options are loaded from the connected account. |
| `layerId` | `string` | Yes | Layer in the Feature Service: numeric layer id as a string (e.g. "0" or "1") or layer name (e.g. "Parcels"); names are matched case-insensitively Options are loaded from the connected account. |
| `fieldName` | `string` | Yes | Layer attribute field name (e.g. "OBJECTID", "CITY_NAME"). Names are case-sensitive and must match the layer schema Options are loaded from the connected account. |
| `searchValue` | `string` | Yes | Value to match against the selected field. Compared with exact string equality; numeric fields may coerce depending on the service |

await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
