maplibre-mcp

Renders two versions of a MapLibre style at the same camera, and returns one image with the style before, the style after, and their differences in red. Use it after changing a style, to check that the change did what you meant and nothing else, at a few places and zoom levels. Pass each style as an object, a URL or a file path.

Says for each layer of a style whether it draws anything at a place and zoom, and when it draws nothing, why: it is hidden or outside its zoom range, the tile lacks its source layer, its filter matches no feature (listed with the values the tile has), a fill layer gets no polygons, its opacity, width or size is 0 or its color transparent, or icons are missing from the sprite. It also notes text that GL JS draws with local fonts and MapLibre Native leaves out, because the style has no glyphs URL or the glyph server lacks its font stack. It reads the vector tiles and GeoJSON data at the place. Use it when a layer draws nothing. Pass the style as an object, a URL or a file path.

Looks up a class, method, option, event or function of MapLibre GL JS, like "Map", "Map#flyTo", "MapOptions.maxPitch", "click" or "addProtocol", in the type definitions that GL JS ships. Returns its signature, documentation, parameters, default and examples, and for a class or an options type, its members. Answers for the GL JS version this server renders with, or for another version, like the one a project uses. Check here before using a method or option you are not sure exists in MapLibre, since Mapbox GL JS has some that MapLibre GL JS does not.

Reads the metadata of every source in a MapLibre style (TileJSON, PMTiles headers and GeoJSON data) and lists the source layers and fields each one provides. Then checks that every layer uses a source, source layer and fields that exist. Use it before writing layers against data you do not know. inspect_tile shows the values the fields take, and debug_layers says what each layer draws at a place. Pass the style as an object, a URL or a file path.

Looks up a name in the MapLibre Style Specification: a layer type (like "fill"), a layer or root property (like "fill-extrusion-height" or "sky"), a source type (like "geojson") or an expression operator (like "interpolate"). Returns its documentation, type, default, allowed values, expression support and which MapLibre GL JS and MapLibre Native versions support it. Check here before using a property you are not sure exists in MapLibre, since Mapbox GL JS has properties that MapLibre does not.

Lists the basemaps in Make with MapLibre (makewithmaplibre.com): ready-made MapLibre styles from OpenFreeMap, Protomaps, MapTiler, Stadia Maps, VersaTiles and others, with their style URLs and whether they need an API key, plus raster and elevation tiles. Pass a style URL as url to render_style or compare_styles to see it, or start a style from it.

Formats a MapLibre style with the keys in the order of the style specification and two space indentation, the same way as gl-style-format. A style given as a file path is formatted in place, otherwise the formatted JSON is returned.

Reads the vector tile of a source at a place and zoom, and lists each source layer with its number of features, their geometry types, the values of each field and a few example features. It also gives the zoom range of the source and the source layers its metadata lists that the tile lacks. Use it to learn the values data really has, like the classes of roads, before writing filters and expressions. The source is either the id of a source in the style you pass, or the URL of a vector source: a TileJSON URL like a Martin source, a PMTiles archive, or a tile URL with {z}, {x} and {y}. Reads MVT and MLT tiles.

Migrates an old style to the current MapLibre Style Specification, the same way as gl-style-migrate: version 7 styles become version 8, and legacy functions and filters become expressions. A style given as a file path is migrated in place, otherwise the migrated JSON is returned.

Renders a MapLibre style to a PNG image, so you can see what the style looks like, for example after changing it. Also reports what the renderer noticed, such as style errors, failed requests, and fonts and icons that are missing. Pass the style as an object, a URL or a file path. Without center, zoom or bounds, the camera stored in the style is used.

Searches Make with MapLibre (makewithmaplibre.com), a curated directory of what works with MapLibre: SDKs and framework bindings, GL JS plugins, routing and navigation, geocoding, styling and tiling tools, AI tools (MCP servers and agent skills), hosted APIs, the products built with MapLibre, and consultancies. Use it to pick an SDK for a platform or framework, find a plugin or a service, find a platform or data source to build on, or see which products use a library. Each result has its links and a page with more. Follow up with find_basemaps for style URLs to render.

Shows the user an interactive MapLibre map in the chat, with GeoJSON layers and markers on an OpenFreeMap basemap. The user sees the map and you do not; to look at a map yourself, use render_style. Without center and zoom, the map fits the layers and markers. Needs a client that supports MCP Apps.

Checks a MapLibre style against the MapLibre Style Specification and lists every problem, each with the path to the property it is about. Run it after editing a style. Pass the style as an object, a URL or a file path.
