GISGP MCP Server

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)

Client config

config.json

{ "mcpServers": { "gisgp": { "url": "https://gisgp.com/mcp" } } }

Local/stdio server (open-source subset)

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:

Terminal

docker build -t gisgp-mcp .
docker run -i --rm gisgp-mcp

config.json

{ "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.

Hosted QA tools (hosted endpoint only)

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_service`	Grade any FeatureServer A–F across 5 categories (schema, completeness, performance, maintenance, configuration) — returns a public shareable scorecard link
`audit_service`	One-call QA report: health + field schema + coded domains + summary counts
`find_layer_issues`	Scan a layer for problems: all-null fields, empty geometries, stale data, missing ObjectID, disabled query
`share_map`	Publish a GeoJSON FeatureCollection as a live shareable web map
`full_service_audit`	Merges grade_service + audit_service + find_layer_issues into a single call
`count_features` / `extract_domains` / `check_field_types` / `check_service_health` / `rest_explore` / `compare_schemas` / `query_features` / `query_statistics`	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.

Layer 2 — paid tools (hosted endpoint only)

Tool	What it does
`estimate_cost`	Free — quote a paid tool's credit cost without executing it
`check_wallet_balance`	Free — check your own MCP credits balance (needs an API key)
`assess_property_hazard`	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
`assess_property_hazard_x402`	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.
