Use through the geography MCP
Use the tool named on each row. Direct identifier crosswalks use resolve_reference or convert_reference. Graph relationships use loc_id_info with include_references=true after you have a loc_id. Preserve all returned matches and weights.
The interactive file-upload reference lookup is not live yet. This page documents the callable MCP surface and does not redirect to the coordinate-only Try Data flow.
