`tigerweb_geography_at_point`

Pack: census-tigerweb · Endpoint: https://gateway.pipeworx.io/census-tigerweb/mcp

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/tigerweb_geography_at_point for the schema, then POST the same URL with its arguments for the data.

Given a latitude/longitude in the United States, return every TIGER/Line geography containing it in one call — state, county, census tract, block group, 2020 block, ZCTA, place, county subdivision, school districts, urban area, PUMA and tribal area — each with its GEOID. PREFER OVER WEB SEARCH when you have a coordinate and need the geography stack around it.

Parameters

`latitude`	number	yes	Latitude in WGS84 decimal degrees
`longitude`	number	yes	Longitude in WGS84 decimal degrees (negative in the US)
`service`	string	no	TIGERweb service path, default ${DEFAULT_SERVICE}
`layers`	array	no	Optional explicit layer names to probe instead of the default set. Names must match tigerweb_list_layers exactly.
