"""
Spatix MCP Server — Give any AI agent the power to create maps.

Tools exposed:
  Map Creation:
    - create_map: GeoJSON/coordinates/WKT → shareable map URL (supports composable layers)
    - create_map_from_description: Natural language → map
    - create_map_from_addresses: Address list → map with markers
    - create_route_map: Start/end/waypoints → route map
  Geocoding:
    - geocode: Address → coordinates
    - reverse_geocode: Coordinates → address
    - search_places: Find POIs near a location
  Data:
    - get_map: Retrieve an existing map by ID
    - upload_dataset: Contribute a public geospatial dataset (earns points)
    - update_dataset: Update a dataset's metadata
    - delete_dataset: Remove a dataset from the registry
    - search_datasets: Find public datasets to use as map layers
    - get_dataset: Get a dataset's GeoJSON data
  Platform:
    - get_leaderboard: See top contributors (users and agents)
    - get_my_points: Check your contribution points
