Two ways in
Choosing where to live
Say who's moving in — "two adults, one dog, trail running, good coffee" — and an agent proposes what to measure. Knowhere measures it, by road and by sidewalk, and the write-up may only report what was measured.
Up to four addresses in one run, compared side by side. A question that couldn't be answered is a dash with a reason, never a neighbour's number. Turn the same questions into a check and grade any list of addresses A–F.
Running an agent
One config entry for Claude Code, Claude Desktop or any MCP client, then ask in plain language. The tools and their docs are written for the model that will read them.
Search, near, route, drive times, walking reach and loops, geocoding, and a sandboxed runtime for the joins the fixed tools can't express.
Stamped on every place
Every place in a US area carries answers OpenStreetMap doesn't have, as a tag on the house itself. Measured against the serving database on 12 September 2026.
Zone X — the safe one?
Not always. Of 855,344 addressed places in Colorado in zone X, 14,236 sit in the 500-year floodplain the bare letter hides.
fema:zone_subtype
How likely is this spot to burn hot?
Rated at 270 m, not by census tract. 15,936 Colorado places rate very high — a house backing onto forest and one three streets in no longer score the same.
usfs:wildfire_hazard
Has it already burned?
2,578 addressed places in Colorado sit inside a wildfire perimeter from 2020 on; 502 of them within 1.5 miles of Superior — the Marshall Fire, mapped to the parcel.
fire:last_burn_year
Also stamped: climate normals, EPA compliance records, radon potential, air-quality days, transport noise and 18 FEMA hazard ratings. Sources and limits are in the category cheat-sheet.
Three real briefs
Written in August 2026 for three households. Every number measured, every map dot placed from coordinates. Unedited.
1840 Elk Hollow Rd
Tabernash, CO
A toddler ski hill in 10, a big resort in 20 — and zero food retail within 3.1 miles. The fun is closer than the groceries.

615 Mesa Vista Ct
Golden, CO
A trailhead 120 m from the door, 116 trail segments within 1.2 miles, Costco in 18 minutes.

2515 Wexford St
Denver, CO
12 cafés within a mile and 7 breweries in walking range — but every dirt trail is a 30-minute drive.
