Pack: hpms-aadt · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

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

Which FHWA HPMS data years exist for a US state and which columns each year carries (the newest years drop route number/name columns), so callers can pick a year before querying.
