ShowMeOnMap MCP server

• add_annotationFree

  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).

• add_fusion_layerFree

  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 the numeric value field from each layer's viz config; pass value_field_a / value_field_b to override. Returns the new layer_id, correlation r, and matched-feature count. Required: map_id, layer_a_id, layer_b_id, rationale.

• add_layerFree

  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 structured plan; otherwise use mutate_map. For the full LayerPlan and Op spec, fetch the MCP resource showmeonmap://docs/workspace-ops-spec.

• build_mapwrite actionFree

  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. For the full Op catalog and predicate grammar that downstream tools (mutate_map, filter_layer, etc.) accept, fetch the MCP resource at showmeonmap://docs/workspace-ops-spec — do NOT guess the shapes.

• clear_filtersFree

  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.

• correlate_layersFree

  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. Use this when you want a numeric answer without rendering; use add_fusion_layer when the user wants the visualization. Required: map_id, layer_a_id, layer_b_id, rationale.

• export_imageFree

  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 rendering; the user's browser is the renderer. Required: map_id, rationale. Optional: format (png default), legend (true default).

• export_layer_dataFree

  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 capability link that does NOT expire — treat it as shareable-forever, not temporary. Required: map_id, layer_id, format, rationale.

• export_workspaceFree

  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. Use this when you want the full raw state for serialization; use get_state when you want the compact envelope for display.

• filter_layerFree

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

• focus_areaFree

  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 clarification with real nearby candidates instead of guessed geometry. Emits ordinary undoable ops (filter / new layer + camera) and a grounded summary like "kept 37 of 150 features". Costs 1 credit when a mutation lands; clarifications are refunded.

• get_stateFree

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

• list_workflowsFree

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

• mutate_mapFree

  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 that case. For the full Op catalog and predicate grammar, fetch the MCP resource showmeonmap://docs/workspace-ops-spec.

• query_featuresFree

  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.

• redoFree

  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 / mutate-map after an undo truncates the redo tail (standard edit-stack semantics).

• remove_annotationwrite actionFree

  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).

• remove_layerwrite actionFree

  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 needs_confirmation envelope is returned.

• rename_layerFree

  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.

• report_blockerFree

  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 direct-op tool returns something you cannot recover from, OR when you would have wanted a different tool to exist. Records the report to a server-side log; does not unblock the current session, but feeds future capability work. No map_id required — file the report even if no map was built.

• restyle_layerFree

  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.

• run_analysiswrite actionFree

  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 field, or on hex-binned point density when valueField is omitted. zonal = aggregate points into polygon zones (an existing zone layer OR a generated h3 fishnet): count/sum/mean/min/max per zone as a quantile choropleth where zero and no-data are distinct classes. enrich = join a US Census ACS indicator (median income, home value, rent, …) onto each feature by tract/county/state containment — unmatched features stay null, never zero-filled. join = spatial join (attribute transfer): each point in layerId takes properties from the joinLayerId polygon containing it (collisions prefixed, unmatched points carry NO joined fields, zero overlap is a typed rejection). merge = append two same-geometry-class layers into one dataset with a per-row source column (schemas never null-filled; class mismatch is a typed failure). near = nearest-neighbor distance columns (great-circle meters, stated — never presented as road distance). dissolve = true polygon union per attribute group (missing values form their own group; partial sums reported). Returns a grounded memo + stats payload — every number is computed, never generated; findings keep the map. Costs 1 credit when the result lands; typed failures (unknown layer, too few features, >10,000-feature cap) are refunded.

• run_workflowwrite actionFree

  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); failed/paused values are reported per value and the batch continues. A clarification pauses a single run (status "paused" + the question); failures stop at the failing step. On success the result is a live map with a shareable URL (batch: the last successful value's map).

• save_workflowFree

  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.

• select_withinwrite actionFree

  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."

• set_cameraFree

  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). Use for "zoom to Japan", "center on Paris at z=10", or finishing a drill-down after filter_layer. Equivalent to the camera move mutate_map would emit, but skips the NL roundtrip.

• set_timeFree

  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 — but the value is captured in the ops log and queryable via get_state.

• tagFree

  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.

• undoFree

  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 rather than silently doing nothing. GATED: pass confirmed:true to proceed; otherwise a needs_confirmation envelope is returned.
