+### Region stores tool
+
+This server also exposes `get_region_stores`.
+
+- Purpose: Returns all stores for a region from `GET /api/regions/{regionId}/stores`.
+- Input:
+  - `regionId` (required, positive integer; OpenAPI path pattern: `[1-9][0-9]*`)
+- Auth: Uses `USERNAME` and `PASSWORD` environment variables to log in and then sends the `X-CSRF-Token` header.
+- Output: Array of typed store list entries including:
+  - identity (`id`, `name`)
+  - region info (`region.id`, `region.name`)
+  - geolocation (`location.lat`, `location.lon`)
+  - address fields (`street`, `city`, `zipCode`)
+  - operational fields (`cooperationStatus`, `categoryType`, `createdAt`)
+
+Notes for consumers:
+
+- `cooperationStatus` is a numeric enum. Known values from the OpenAPI schema: `0, 1, 2, 4, 5, 6, 7`.
+- `categoryType` is a numeric enum. Known values from the OpenAPI schema: `0, 1, 2`.
+- `createdAt` is delivered as a date string in `YYYY-MM-DD` format.
+- Some raw API values may contain trailing spaces or empty strings in address fields; this tool returns the original API data unchanged.
+
+The tool is strongly typed in `Tools/RegionStoresTools.cs`, with per-field `Description` attributes so MCP clients can surface schema-aware guidance directly in tool UIs.
