Use cases
What people ask Isopleth for, with a prompt to try in your assistant and the exact tools and fields behind it. Point data works at every US coordinate; parcel records cover 27 states plus DC (82,061,082 parcels, see coverage).
1. Connect your assistant

ChatGPT on the web (Pro, Business, Enterprise and Edu). Sign in with Isopleth; no key to paste.
- Open Plugins, select +, then Add custom MCP server (older layouts: Settings → Apps → Create, with developer mode on).
- Paste the URL, name it Isopleth, choose OAuth and leave the client ID and secret blank.
- Sign in to Isopleth when asked, choose Allow access, then type
@Isoplethin a chat.

One command, then /mcp inside Claude Code to sign in in your browser.
claude mcp add --transport http isopleth https://api.isopleth.dev/mcp
claude mcp add --transport http isopleth https://api.isopleth.dev/mcp --header "Authorization: Bearer $ISOPLETH_KEY"
One click opens Cursor's install prompt. Cursor signs you in to Isopleth the first time a tool runs.

}One click opens VS Code's MCP install page (Copilot agent mode). VS Code offers to sign in to Isopleth.

}One command. Codex sees that Isopleth supports sign-in and opens your browser.
codex mcp add isopleth --url https://api.isopleth.dev/mcp
codex mcp add isopleth --url https://api.isopleth.dev/mcp --bearer-token-env-var ISOPLETH_KEY
Use Add to Claude on the Claude tab: connectors added on claude.ai appear in Claude Desktop. To use an API key instead, add this to claude_desktop_config.json (Settings → Developer → Edit Config; needs Node.js 18+).

],
"env": {

}
}Paste into ~/.codeium/windsurf/mcp_config.json (Cascade → MCP → open config). Windsurf uses serverUrl, not url.

}
}Any client that speaks Streamable HTTP: the URL, then the client's OAuth sign-in or the header Authorization: Bearer <your key>. Stdio-only clients can use the mcp-remote bridge shown under Claude Desktop.

2. Pick a job
Land buyers
Find the acreage, then read the dirt.
Search parcels by county, acreage, owner name or land use in 27 states plus DC, then screen each one for slope, soils, flood zone, road access and water service before you drive out.
“Find parcels of 40 to 160 acres in Llano County, Texas whose owner name contains RANCH. For the five largest, tell me the slope, soil drainage, flood zone and how far each is from a paved road.”
Connect Isopleth in that app first (one click above), so the assistant can call it.

Fields slope_degrees soil_drainage_class nfhl_flood_zone nearest_road_surface nearest_major_road_distance_m within_water_service_area
Solar and wind siting
Screen a site before you call the utility.
Irradiance and wind resource, distance to transmission and substations, nearby existing projects, slope and protected land, in one call per pin. Presets solar_siting and wind_siting bundle them.
“Compare these three pins in New Mexico for a 5 MW solar array: irradiance, slope, distance to the nearest substation and transmission line, and whether any of them touch protected land.”

Insurance underwriting
Hazards for a whole book, with sources.
Flood zone and base flood elevation, wildfire history and frequency, tornado and hail frequency and distance to the fire station, re-run in batches whenever the book changes.
“Here are 50 policy addresses. Flag any in a FEMA A or V zone, within 2 km of a past wildfire perimeter, or more than 8 km from a fire station.”

Lenders and appraisers
Collateral context in one read.
Hazard exposure plus county trends (home prices, income, population growth, permits) and opportunity-zone status, with the parcel's owner, assessed value and last sale where we hold parcels (27 states plus DC).
“For this farm loan at 38.71, -98.92: county home-price trend, median income, population growth, whether it's in an opportunity zone, the flood zone, and the parcel's assessed value and last sale.”

Real estate agents
Answer the buyer's questions before they ask.
Flood zone, distance to schools and hospitals, water and sewer service, road surface and wildfire exposure for a listing, plus acreage and zoning from the parcel record where we hold it.
“I'm listing 12 acres at this address. Write a one-page fact sheet: flood zone, nearest school and hospital, water and sewer service, road surface and acreage, with sources.”

CRM address cleanup
Messy addresses in, clean coordinates out.
Normalize lead and customer addresses to coordinates with an accuracy score, and get a review queue for anything that didn't match. Addresses that don't resolve aren't charged.
“Clean up these 200 addresses from our CRM export. Give me normalized address, lat and lng for each, and list the ones that need a human.”
Connect Isopleth in that app first (one click above), so the assistant can call it.
Tools geocode_address get_usage
Fields none: returns normalized address, lat, lng and accuracy
Telecom and towers
Know the terrain before the truck rolls.
Distance to and count of registered antenna structures, elevation, slope and aspect, tree canopy, road access and protected land: the facts a tower or fixed-wireless site plan starts with.
“For these 20 candidate tower sites, how far is each from the nearest registered antenna structure and how many are within 2 km? Include elevation, tree canopy and distance to a major road.”

Agriculture
Soil, water and weather at the field.
Soil drainage and hydrologic group, prime farmland class, the crop grown there in recent years, drought, rainfall normals, frost days and depth to groundwater at the nearest well.
“I'm looking at a quarter section at 41.12, -100.76. What's the soil drainage and farmland class, what's been planted the last five years, current drought, annual rainfall and depth to water at the nearest well?”
