Mapbox

Calculate the area of a polygon or multipolygon. Supports various units including square meters, kilometers, acres, and hectares. Works offline without API calls.

Calculate the bounding box (extent) of any geometry. Returns the minimum and maximum longitude and latitude that encompass the geometry. Works offline without API calls.

Calculate the bearing (compass direction) from one point to another. Returns bearing in degrees where 0° is North, 90° is East, 180° is South, and 270° is West. Works offline without API calls.

Create a buffer zone (polygon) around a point, line, or polygon at a specified distance. Useful for proximity analysis, service areas, or creating zones of influence. Works offline without API calls.

Return all places that match a category (industry, amenity, or NAICS‑style code). Use when the user asks for a type of place, plural or generic terms like 'museums', 'coffee shops', 'electric‑vehicle chargers', or when the query includes is‑a phrases such as 'any', 'all', 'nearby'. Do not use when a unique name or brand is provided. Supports both JSON and text output formats.

Calculate the geometric center (centroid) of a polygon or multipolygon. The centroid is the arithmetic mean position of all points in the shape. Works offline without API calls.

Compute the convex hull of a set of points — the smallest convex polygon that contains all the points. Useful for bounding area analysis, estimating coverage area, or wrapping a set of locations. Works offline without API calls.

Calculate a destination point given a starting point, bearing, and distance using geodesic (great-circle) straight-line offset. Useful for "find a point 5km north of X", constructing search offsets, or computing waypoints. Bearing: 0=north, 90=east, 180/-180=south, -90=west. Note: this calculates a straight-line geographic offset, not road-network distance. Works offline without API calls.

Subtract one polygon from another, returning the area in polygon1 that is not covered by polygon2. Useful for computing exclusion zones, finding uncovered service areas, or "what is in zone A but not zone B?". Returns null geometry if polygon2 fully covers polygon1. Works offline without API calls.

Fetches directions from Mapbox API based on provided coordinates and direction method. For route planning and distance calculations, use geometries="none" to get compact responses. Only request full geometry (geometries="geojson") when you need to visualize the route on a map or provide detailed turn-by-turn navigation instructions.

Calculate the distance between two geographic coordinates. Supports various units including kilometers, miles, meters, feet, and nautical miles. Uses the Haversine formula for accurate great-circle distance calculations. This tool works offline without requiring API calls.

Answer questions about what is near a location, what neighborhood a coordinate is in, or what places are within walking/driving distance. Use this as the FIRST and ONLY tool when given coordinates and asked about nearby places, neighborhood context, local discovery, or area summaries — do NOT also call reverse_geocode_tool or search the web for places. Pass the place category (e.g. "restaurant", "coffee", "park") as the query parameter to get nearby POIs in the same call. Returns place name, nearby POIs matching the query, and travel-time reachability — all sourced from live Mapbox data with citations.

Find the intersection geometry of two polygons — the area they share in common. Useful for coverage overlap analysis, finding shared service areas, or zone overlap. Returns null geometry if the polygons do not overlap. Works offline without API calls.

Computes areas that are reachable within a specified amount of time from a location, and returns the reachable regions as contours of Polygons or LineStrings in GeoJSON format that you can display on a map. Common use cases: - Show a user how far they can travel in X minutes from their current location - Determine whether a destination is within a certain travel time threshold - Compare travel ranges for different modes of transportation'

Measure the total length of a line defined by a series of coordinates. Useful for measuring a drawn route, path, or boundary without a routing API call. Supports kilometers, miles, meters, and feet. Works offline without API calls.

Snap GPS traces to roads using Mapbox Map Matching API. Takes noisy/inaccurate coordinate sequences (2-100 points) and returns clean routes aligned with actual roads, bike paths, or walkways. Useful for analyzing recorded trips, cleaning fleet tracking data, or processing fitness activity traces. Returns confidence scores, matched geometry, and optional traffic/speed annotations.

Calculates travel times and distances between multiple points using Mapbox Matrix API.

Calculate the geographic midpoint between two coordinates. Returns the point that is halfway between the two input points along the great circle path. Works offline without API calls.

Snap a point to the nearest position on a line or route. Returns the closest point on the line and the distance to it. Useful for "which point on this route is closest to my location?" or map-matching without the API. Works offline without API calls.

Find the nearest point in a collection to a given target point. More efficient than calling distance_tool for each candidate and sorting. Useful for finding the closest store, stop, or landmark to a location. Works offline without API calls.

Find the optimal (shortest by travel time) route through a set of 2-12 coordinates. Solves the Traveling Salesman Problem to determine the best visiting order. Supports options for starting point, ending point, and whether to return to start.

Retrieve detailed information about a specific place using its Mapbox ID. Use after search_and_geocode_tool, category_search_tool, or reverse_geocode_tool to get additional details such as photos, opening hours, ratings, phone numbers, and website URLs. Requires the mapbox_id field from a previous search result.

Test one or more geographic points against a polygon, returning only those inside. Handles a single point or a batch of points in one call. Useful for delivery zone validation, fleet geofencing, and customer segmentation. Works offline without API calls.

Convert geographic coordinates (longitude, latitude) into a human-readable address or place name. Use only when you need an address/place name alone. If you also need nearby places, neighborhood context, or travel-time reachability, use ground_location_tool instead — it already includes reverse geocoding plus POI search and isochrone in one call. This tool cannot reverse geocode businesses, landmarks, or POIs. Supports JSON and text output formats.

Search for POIs, brands, chains, geocode cities, towns, addresses. Do not use for generic place types such as 'museums', 'coffee shops', 'tacos', etc, because category_search_tool is better for that. Setting a proximity point is strongly encouraged for more local results.

Simplify a LineString or Polygon by reducing the number of vertices while preserving the general shape. Uses the Douglas-Peucker algorithm. Useful for reducing file sizes and improving rendering performance. Works offline without API calls.

Generates a static map image from Mapbox Static Images API. Supports center coordinates, zoom level (0-22), image size (up to 1280x1280), various Mapbox styles, and overlays (markers, paths, GeoJSON). Returns PNG for vector styles, JPEG for raster-only styles.

Merge two or more polygons into a single unified geometry. Useful for combining service areas, delivery zones, isochrones, or coverage regions. Returns a Polygon or MultiPolygon if the inputs do not overlap. Works offline without API calls.
