32 tools

• get_map_view

  Used by the ShowMeOnMap map card to load a map version. Not for the model.

• build_map

  Make an interactive, data-driven map from a plain-language request, built from live public data with every value cited to its source. Covers natural hazards (earthquakes, wildfires, volcanoes, tropical storms, floods), weather and air quality, statistics by country, state or…

• osm_features

  Map and list OpenStreetMap objects matching exact OSM tags inside an area — a bbox, a point and radius, or a named place. Use when you know the tags ("place=village|hamlet", "amenity=clinic", "railway=tram", "highway=*+name=Rue de Lyon") or need everything near a coordinate with…

• analyze

  One call for a question that combines datasets: "which Asian capitals had the most earthquakes within 300 km this month", "people within 30 km of each volcano in Indonesia", "how much of each African country is desert". Give a plan: acquire steps (ask = a dataset in plain words…

• mutate_map

  Apply a natural-language instruction to an existing workspace. Valid mutations: filter a layer, remove a layer, change camera, change basemap. For ambiguous instructions the tool emits a clarification field. For unrelated instructions it emits outOfScope — build a new map in…

• get_state

  Return the current workspace, map plan, and active filters for a given map_id.

• add_layer

  Append a fully-constructed LayerPlan to an existing workspace without going through NL. Pass the same shape the workspace pipeline emits — { id, title, source, viz, geometry, ... }. Takes a structured plan; natural-language edits go through mutate_map. The full LayerPlan and Op…

• add_fusion_layer

  Spatially join two existing layers and add a new layer that encodes both values per region as a 3x3 bivariate choropleth. Both layers must already exist in the workspace. Auto-detects the numeric value field from each layer's viz config; pass value_field_a / value_field_b to…

• correlate_layers

  Spatially join two existing workspace layers and return the Pearson correlation coefficient r, sample size n, two-sided p-value approximation, plus human-readable strength and direction labels. Pure read — no layer is added, no op is committed, no credit charge. Returns numbers…

• filter_layer

  Narrow a layer to features matching a structured predicate. `append:true` (default) conjoins with any existing filter; `append:false` replaces the chain.

• select_within

  Create a new layer containing the source layer's features that lie within the supplied polygon. The source layer is untouched. Useful for "show me only the X inside this country/bbox/hand-drawn shape."

• focus_area

  Refine an existing layer to a NAMED area the server resolves from OpenStreetMap — a street corridor ("Broadway from Arbutus Street to Main Street"), a place ("Mount Pleasant"), or an intersection surroundings. Pass names only, never coordinates; unresolvable names return a…

• run_analysis

  Compute a spatial analysis server-side and append the finished, honestly-legended result as a new layer + camera; the result REPLACES its input layer(s) (undoable). hotspot = Getis-Ord Gi*: hot/cold significance classes (99/95/90%, Benjamini-Hochberg FDR-corrected) on a numeric…

• query_features

  Evaluate a predicate against a layer's inline features and return the matching subset. No Op is emitted and the workspace is not mutated. Handy for introspection ("how many X match Y?") before deciding whether to filter, subset, or build a new layer.

• remove_layer

  Drop a layer from the workspace by id. Strict: removing an already-removed or never-added layer fails. Layer ids do NOT recycle — a removed id cannot be re-added later in the same workspace. GATED: this tool is destructive. Pass confirmed:true to proceed; otherwise a…

• clear_filters

  Wipe every predicate currently applied to a layer's filter chain, making every source feature visible again. Inverse of filter_layer. No-op on layers that have no existing filter. GATED: pass confirmed:true to proceed; otherwise a needs_confirmation envelope is returned.

• rename_layer

  Change a layer's id from oldLayerId to newLayerId. Re-keys any existing filter chain and preserves insertion order among sibling layers. Strict: newLayerId must not already be in use (current OR tombstoned) in this workspace. Subsequent ops must reference the layer by its new id.

• restyle_layer

  Adjust a layer's color and/or opacity. Within-palette changes only — the renderer silently ignores fields the current viz variant doesn't support. Pass at least one of color / opacity; passing neither is an accepted no-op.

• set_camera

  Override the workspace camera. Latest set_camera op wins during replay. Two modes: `fitBounds` with a [w,s,e,n] bbox (plus optional padding/animateMs), or `flyTo` with [lng,lat] center + zoom (plus optional pitch/bearing/animateMs). Covers requests like "zoom to Japan", "center…

• set_time

  Override the current time-range filter. Latest set_time op wins during replay. Covers requests like "filter to 2020-2024" or "show only the last 7 days". Not yet consumed by the renderer — the UI drives the slider directly — but the value is captured in the ops log and queryable…

• tag

  Label the current workspace state with a user-supplied name. The label is mirrored into workspace.meta.tags so UIs can render a named-revision history. Tagging the same label twice is idempotent — no error, no duplicate entry.

• add_annotation

  Add a user-placed label at a specific coordinate. Annotations are independent of layers and live in their own id namespace. Strict: the id must not already be in use by another CURRENTLY-placed annotation (removed ids can be recycled).

• remove_annotation

  Drop a previously-placed annotation by id. Strict: removing an already-removed or never-placed id fails. After removal, the id CAN be re-used by a later add_annotation (unlike layer ids, which are tombstoned for the session).

• export_workspace

  Return the current workspace document (ops log + cursor + meta) plus the materialized mapPlan and layerFilters, in a shape suitable for save-to-file / share-by-URL / inspection. Pure read — no mutation, no credit charge. This is the full raw state for serialization; get_state…

• export_layer_data

  Export a single layer's features as a downloadable file. Returns a URL with Content-Disposition: attachment so the user's browser downloads it. CSV drops geometry beyond a (lng, lat) centroid — for full polygon/line geometry, use format: "geojson". The URL is an unguessable…

• export_image

  Returns a deep-link URL that opens the map in the user's browser and automatically triggers a PNG download. The user clicks the link, the browser renders the map at full resolution with the legend composited (if legend: true), and the file downloads. There is no server-side…

• undo

  Rewind the workspace cursor by one, re-materializing the state as it was before the last mutation. Does NOT delete any ops — redo will fast-forward. Calling undo at the workspace genesis (cursor === 0, only the CreateWorkspace op is in scope) is a no-op that surfaces an error…

• redo

  Advance the workspace cursor by one toward the tail of the ops log, replaying the next op that was previously undone. Calling redo when the cursor is already at the tail (no undone ops to fast-forward) fails rather than silently no-op. Note: any new op applied via apply-op /…

• report_blocker

  Send the ShowMeOnMap team a report about a request this server could not complete — an unsupported intent, a missing tool, an unclear schema, or an op that failed in a confusing way. Records the report to a server-side log for future capability work; it does not change the…

• save_workflow

  Save a re-runnable, parameterized workflow: an ordered list of natural-language instructions (step 1 builds, later steps mutate). Wrap values in {braces} and declare them in params. Running it later re-executes the instructions on FRESH data and bills per step like typing.

• list_workflows

  List the caller's saved workflows with their parameters and per-run credit estimates.

• run_workflow

  Execute a saved workflow with parameter values. PAID: bills ~1 credit per step through the normal build/mutate paths (the estimate is in list_workflows). Optional batch mode sweeps ONE param across 2–20 values — each value is a full independent run (steps × values credits)…
