| Tool | What it does | Hint |
|---|---|---|
build_mapBuild a map | Create a new workspace from a natural-language query. Returns a map_id you can pass to mutate_map or get_state for follow-up actions. The Op catalog and predicate grammar that downstream tools (mutate_map, filter_layer,… | writes |
mutate_mapMutate a 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… | writes |
get_stateRead map state | Return the current workspace, map plan, and active filters for a given map_id. | read-only |
add_layerAdd a layer (direct) | 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, ... }. Prefer this when you already have a… | writes |
add_fusion_layerAdd bivariate 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 (call build_map or add_layer first). Auto-detects… | writes |
correlate_layersCompute correlation between two 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… | read-only |
filter_layerFilter a layer (direct) | Narrow a layer to features matching a structured predicate. `append:true` (default) conjoins with any existing filter; `append:false` replaces the chain. | writes |
select_withinSubset a layer to a polygon selection | 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." | read-only |
focus_areaFocus a layer on a named 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… | writes |
run_analysisRun a spatial analysis on a layer | 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… | writes |
query_featuresQuery features from a layer (read-only) | 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… | read-only |
remove_layerRemove a layer (direct, destructive) | 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… | writes |
clear_filtersClear all filters on a layer (direct, gated) | 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;… | writes |
rename_layerRename a layer (direct) | 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… | writes |
restyle_layerRestyle a layer (direct) | 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… | writes |
set_cameraSet the map camera (direct) | 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… | writes |
set_timeSet the time window (direct) | Override the current time-range filter. Latest set_time op wins during replay. Use for "filter to 2020-2024" or "show only the last 7 days" intents. Not yet consumed by the renderer — the UI drives the slider directly —… | writes |
tagSave a named checkpoint (direct) | 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… | writes |
add_annotationPlace an annotation on the map (direct) | 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… | writes |
remove_annotationRemove an annotation (direct) | 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… | writes |
export_workspaceExport the workspace JSON | 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… | read-only |
export_layer_dataExport 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… | read-only |
export_imageExport map as 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:… | read-only |
undoUndo the most recent op (gated) | 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… | writes |
redoRedo a previously-undone op | 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… | writes |
report_blockerReport a blocker (agent feedback) | Tell the ShowMeOnMap team your agent hit something it could not accomplish — an unsupported intent, a missing tool, an unclear schema, an op that failed in a confusing way. Use this when build_map / mutate_map / a… | writes |
save_workflowSave a 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… | writes |
list_workflowsList saved workflows | List the caller's saved workflows with their parameters and per-run credit estimates. | read-only |
run_workflowRun a saved 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… | writes |
