Mapsource Geospatial API
Description
OSM queries, raster tiles, elevation. Check status: queries currently use fixtures; x402 is testnet.
What our measurements say
Mapsource Geospatial API is a remote MCP server published at mapsource.io. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 875 ms, a delay an agent will notice. It offers a narrow, focused set of 13 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Comprehensive coverage of geospatial operations (elevation, routing, rendering, analysis).
- Some tools (e.g., 'elevation', 'route') have well-defined parameters with clear required fields.
Weaknesses
- Tool names like 'geo_data' and 'geo_style' are overly generic and do not clearly indicate their specific functions.
- Descriptions often focus on capabilities rather than use cases (e.g., 'geo_analyze' lacks context for when to use specific operations).
- Parameter definitions in some tools (e.g., 'geo_style') are incomplete or ambiguous (e.g., 'patch' type is 'object' but lacks structure details).
geo_data— Overlapping functionality with 'service_status' and 'basemap_catalog' creates ambiguity for agents.geo_style— Description is too vague about when to use operations like 'intent' or 'preview'.overpass_query— Lacks explicit error handling for invalid queries or unsupported historical data.find_features— Parameter 'responseMode' is not explained in the description, making its purpose unclear.

Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 190ms → warm 191ms (penalty 0ms)
Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
service_statusRead Overpass engine readiness, dataset timestamp, billing state, and x402 payment mode. Public. Use geo_data with operation status for the full subsystem report.
basemap_catalogList raster and vector tile templates, source zoom ranges, dataset snapshots, and attribution. The catalog is public; tile requests require a subscription key.
elevationSample terrain at lat/lon. elevationMeters is clamped to zero; sampledMeters retains the raw model elevation. belowSeaLevel identifies negative samples and bathymetryTile references the source raster. Requires a subscription key. Not survey-grade.
latnumberrequiredlonnumberrequired
geo_dataRead service status, basemap catalog, point elevation, contours, usage, and metrics. Status includes subsystem availability and replication lag. Elevation returns surface and raw model heights. Metrics report request rates, success rates, latency percentiles, and dataset ages. Status and basemaps are public; other operations require a subscription key.
operationstringrequiredlatnumberlonnumberzoomintegerbandsintegerwindowinteger
geo_styleConfigure semantic basemap styles. Operations: explain and schema retrieve public definitions; intent generates a proposal; preview compiles changes; save, list, revisions, diff, and delete manage profiles. Submit semantic manifests or preset patches, not raw MapLibre JSON. Authenticated operations affect the current key's profiles.

geo_renderRender a static PNG map from a center and zoom or bounding box. Supports GeoJSON overlays, result handles, and up to 50 labeled markers. Dark and light styles use raster rendering; other preset or profile names use vector rendering. Requires a subscription key.

geo_analyzeMeasure or transform geometry using buffer, centroid, bbox, area, length, distance, intersect, union, difference, contains, intersects, nearest, simplify, or convex. Inputs accept GeoJSON, coordinate pairs, Overpass results, and result handles. Polygon overlay operations require areas. Use operation pipeline for up to 12 ordered steps and estimateOnly for cost estimation. Requires a subscription key.

geo_searchSearch places and retrieve geographic entities. Operations: search, autocomplete, nearby, reverse, details, geocode, resolve, and entity. Optional coordinates bias name searches. Nearby results are ordered by distance; resolve reports ambiguous matches as candidates. Records retain OSM identifiers and source metadata. Requires a subscription key.

geo_navigateNavigation operations: route, matrix, isochrone, map_match, snap, and optimize. Route accepts 2–10 waypoints and optional elevation profiles. Matrix supports up to 625 pairs. Map matching accepts up to 1,000 trace points; optimization accepts 3–20 stops. Results include geometry or travel costs and source metadata. Requires a subscription key. Unroutable requests return an error and require revised inputs.

routeCalculate a turn-by-turn route between 2–10 waypoints. Supported costing: auto, bicycle, pedestrian, truck, motor_scooter, and bus. Returns GeoJSON, distance, duration, and maneuvers. Set elevation to true for a terrain profile with gain and loss. Requires a subscription key.

isochroneCalculate reachable-area polygons from a coordinate for up to four travel-time bands. Returns GeoJSON for catchment, coverage, and accessibility analysis. Requires a subscription key.

overpass_queryExecute bounded Overpass QL over OSM nodes, ways, relations, tags, geometry, areas, metadata, and spatial selectors. Historical attic queries are unsupported. Requires a subscription key or authorized x402 payment. Use service_status to retrieve the dataset timestamp.
