`tigerweb_list_layers`

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_list_layers for the schema, then POST the same URL with its arguments for the data.

List the queryable TIGER/Line geography layers in a Census TIGERweb ArcGIS service — census tracts, block groups, 2020 blocks, ZCTAs, congressional and state legislative districts, school districts, tribal areas, places, counties, PUMAs. Call this FIRST to get the layer_id that tigerweb_query needs; layer numbers differ between vintages, so never reuse one from memory.

Parameters

Name	Type	Required	Description
`service`	string	no	TIGERweb service path, default ${DEFAULT_SERVICE}. Others: ${Object.keys(SERVICE_HINTS).join(’, ’)}
`filter`	string	no	Case-insensitive substring to filter layer names, e.g. “school”
`include_label_layers`	boolean	no	Include ”… Labels” annotation layers (point labels, not boundaries). Default false.
