Useful for

Use cases llm-inferred: Pull OS NGD building and road features for a site boundary as a GIS baseline for FRA or drainage design · Filter OS NGD features by attribute and location to build customised layers for constraints mapping · Extract current OS NGD feature data on demand for desk-based site assessments
Audience llm-inferred: GIS analysts · flood risk consultants · drainage engineers · civils engineers · planners · environmental consultants

Limitations

Constraints llm-inferred: Dataset licence field is 'Not set' on the publisher page, so reuse terms should be confirmed before use · Requires network access to the OS API endpoint · Per-collection resolution, attribute schema and coverage periods are not stated in the docs · No MCP tools listed in ENTRY, so this is a raw API rather than a ready-made tool integration
