Test the connection to ArcGIS Pro and get the full project status: version, project path, list of maps/scenes/globes, active map, and whether a view is currently open. Always call this first to understand the current state before running any other operations.

Get information about the currently open ArcGIS Pro project: file path, geodatabase, and list of maps.

Get the name of the active map currently shown in ArcGIS Pro.

List all layers in the active map (or a specific map by name).

Args: map_name: Optional map name. If empty, uses the active map.

Add a vector layer (shapefile, feature class, GeoJSON, etc.) to the active map.

Args: path: Full path to the data source (e.g. C:/data/roads.shp or a feature class path)

Add a raster layer (GeoTIFF, IMG, etc.) to the active map.

Args: path: Full path to the raster file (e.g. C:/data/dem.tif)

Remove a layer from the active map by name.

Args: name: Exact layer name as shown in the Contents pane

Zoom and pan the active map view to show the full extent of a layer.

Args: name: Exact layer name as shown in the Contents pane

Count the total number of features (rows) in a layer.

Args: layer: Exact layer name as shown in the Contents pane

Select features in a layer using a SQL WHERE clause.

Args: layer: Exact layer name as shown in the Contents pane where_clause: SQL expression (e.g. "population > 100000" or "type = 'road'") selection_type: NEW_SELECTION, ADD_TO_SELECTION, REMOVE_FROM_SELECTION, SUBSET_SELECTION (default: NEW_SELECTION)

Update attribute values on features matching a WHERE clause. Sets the same field value(s) on every matching row (bulk update). For per-row computed values (e.g. incrementing a counter), use execute_python with an UpdateCursor instead.

Args: layer: Exact layer name as shown in the Contents pane where_clause: SQL expression selecting which rows to update (e.g. "STATUS = 'Pending'"). Pass "" to update every row in the layer — be deliberate about this. updates: Dict of {field_name: new_value} applied to every matching row, e.g. {"STATUS": "Verified", "REVIEWED_BY": "GIS Team"}

Save the current ArcGIS Pro project.

Run any ArcPy geoprocessing tool by its dotted name.

Args: tool: Dotted tool name, e.g. "analysis.Buffer", "management.CopyFeatures", "conversion.FeatureClassToShapefile" params: List of positional parameters for the tool, e.g. ["roads", "output_buf", "100 Meters"]

Example: run_geoprocessing("analysis.Buffer", ["C:/data/roads.shp", "C:/data/roads_buf.shp", "500 Meters"])

List all fields in a dataset (shapefile, feature class, table, layer name, etc.) with field type, length, and alias. Use this before building WHERE clauses or running attribute operations.

Args: dataset: Full path to dataset, or layer name as shown in Contents pane

List feature classes in a workspace (folder, GDB, or feature dataset).

Args: workspace: Path to workspace/GDB (e.g. C:/data/mydb.gdb). Uses current workspace if empty. pattern: Wildcard filter, e.g. "road*" (default: "*") feature_type: Filter by geometry — Point, Line, Polygon, etc. (default: all)

List raster datasets in a workspace.

Args: workspace: Path to workspace/folder. Uses current workspace if empty. pattern: Wildcard filter (default: "*") raster_type: Filter by type — TIF, IMG, GRID, etc. (default: all)

List standalone tables in a workspace (GDB tables, DBF files, etc.).

Args: workspace: Path to workspace. Uses current workspace if empty. pattern: Wildcard filter (default: "*")

Set arcpy.env.workspace — the default location for inputs/outputs when no full path is provided to geoprocessing tools.

Args: workspace: Full path to folder or GDB (e.g. C:/data or C:/data/mydb.gdb)

Get the current arcpy.env.workspace setting.

Clear any active selection on a layer.

Args: layer: Exact layer name as shown in the Contents pane

Get all unique values in a field. Useful for exploring data and building WHERE clauses for select_by_attribute.

Args: layer: Exact layer name as shown in the Contents pane field: Field name to get unique values for limit: Max number of unique values to return (default: 100)

Toggle a layer's visibility in the Contents pane.

Args: layer: Exact layer name as shown in the Contents pane visible: True to show, False to hide

Create a new map in the current ArcGIS Pro project. After creation, open it by double-clicking it in the Catalog pane under Maps.

Args: name: Name for the new map (default: "Map")

Describe a dataset — returns coordinate system, geometry type, extent, and data type. Use this to verify a file exists and check its projection before geoprocessing.

Args: path: Full path to the dataset (shapefile, raster, feature class, GDB, etc.)

List files in a directory, optionally filtered by pattern.

Args: path: Full path to the directory (e.g. C:/Users/User/Documents/Rusunawa) pattern: Glob pattern to filter results (e.g. ".shp", ".tif", default: "*")

Create a new layout in the project with a map frame already added. After creation, call export_layout() to export it as PDF/PNG/etc.

Args: name: Layout name (default: "Layout") map_name: Map to put in the frame — uses active map if empty width: Page width (default: 11) height: Page height (default: 8.5) units: Page units — INCH, CENTIMETER, MILLIMETER, POINT (default: INCH) margin: Frame margin from page edge in page units (default: 0.5)

Execute arbitrary Python/arcpy code inside the ArcGIS Pro bridge. Use this for complex arcpy.mp operations not covered by other tools.

Available variables: arcpy, os, proj (the ArcGISProject), get_map() Set result = in your code to return data. print() output is captured and returned as 'stdout'.

Example: code = """ m = proj.listMaps()[0] result = [lyr.name for lyr in m.listLayers()] """

List all layouts in the current ArcGIS Pro project with their page size and units.

Export a layout to a file (PDF, PNG, JPG, BMP, TIF, SVG, or EPS).

Args: name: Exact layout name as shown in the Catalog pane output: Full output file path including extension (e.g. C:/output/map.pdf) format: Export format — PDF, PNG, JPG, BMP, TIF, SVG, EPS (default: PDF) dpi: Resolution in dots per inch for raster formats (default: 150)

Preview rows from a layer's attribute table.

Args: layer: Exact layer name as shown in the Contents pane limit: Number of rows to return (default: 10) fields: List of field names to include. If empty, returns all non-geometry fields.

Publish a layer as a hosted feature service to ArcGIS Online / Enterprise, using whichever portal is currently active in ArcGIS Pro. Always confirm with the user before calling this — it creates or overwrites content on their portal account.

Publishes over REST via the ArcGIS API for Python (reusing your existing Pro sign-in — no separate login needed), not the classic arcpy.server pipeline, which doesn't work reliably from this bridge. Can take up to ~30-60s for typical layers; this is normal, don't treat a slow response as a failure.

Args: layer: Exact layer name as shown in the Contents pane service_name: Name for the hosted feature service (must be unique in the target folder) summary: Short description shown on the portal item (optional) tags: Comma-separated tags for the portal item (optional) public: Share publicly if True; private (owner-only) if False (default: False) overwrite: Overwrite an existing service with the same name if True (default: False)
