Automates ArcGIS Online and FeatureServer operations: query features, statistics, convert formats (GeoJSON, CSV, KML, Shapefile, GPX, WKT), validate and reproject geospatial data.
Free remote MCP (Model Context Protocol) server for GIS/ArcGIS Online automation.
Endpoint: https://gisgp.com/mcp (Streamable HTTP, stateless, no auth for public layers)
{ "mcpServers": { "gisgp": { "url": "https://gisgp.com/mcp" } } }Related MCP server: geo-mcp
server.py is a self-contained, open-source MCP server (stdio transport)
implementing the format-conversion and geometry tools that need no external
service access — no ArcGIS Online credentials, no network calls. Build and
run it with the included Dockerfile:
docker build -t gisgp-mcp .
docker run -i --rm gisgp-mcp{ "mcpServers": { "gisgp-local": { "command": "docker", "args": ["run", "-i", "--rm", "gisgp-mcp"] } } }The tools that inspect/query a live ArcGIS Online FeatureServer
(count_features, extract_domains, check_field_types,
check_service_health, rest_explore, compare_schemas, query_features,
query_statistics) require a real AGOL connection and stay on the hosted
remote endpoint above — they are not part of this local server.
The hosted server at https://gisgp.com/mcp also exposes ArcGIS Online QA tools that
need a live AGOL connection and can't run in this local/stdio server:
Tool | What it does |
| Grade any FeatureServer A–F across 5 categories (schema, completeness, performance, maintenance, configuration) — returns a public shareable scorecard link |
| One-call QA report: health + field schema + coded domains + summary counts |
| Scan a layer for problems: all-null fields, empty geometries, stale data, missing ObjectID, disabled query |
| Publish a GeoJSON FeatureCollection as a live shareable web map |
| Merges grade_service + audit_service + find_layer_issues into a single call |
| Inspect/query a live ArcGIS FeatureServer |
Also hosted-only: get_terrain_profile, get_climate_history, classify_land_cover,
analyze_location — free geo primitives backed by third-party open-data APIs
(Open-Meteo, ESA CCI Land Cover, OSM Nominatim), kept on the hosted endpoint rather
than this offline server since they need outbound internet access to those services.
Tool | What it does |
| Free — quote a paid tool's credit cost without executing it |
| Free — check your own MCP credits balance (needs an API key) |
| Paid, 200 credits (€0.20) — multi-source US property hazard: USGS seismic risk + FEMA 10-year disaster history + NOAA active weather alerts, charged via credits wallet |
| Paid, ~$0.20 via the x402 protocol — same multi-source hazard data, paid directly in USDC on-chain (Base), no GISGP account needed |
These require live infrastructure (ArcGIS/S3, DynamoDB credits wallet, or third-party APIs) and are not part of the open-source subset below — everything below runs fully offline.
40 tools in this local/offline server subset (see the hosted-only sections above for the full 92-tool catalog including AGOL QA/query tools and Layer 2 paid tools).
