{"jsonrpc":"2.0","id":1,"method":"tools/list"}ukplanning_datasets — List the datasets published on planning.data.gov.uk — the UK government's national planning data platform (MHCLG). Each row gives the dataset slug you pass to the other tools, its plain-English name, typology, licence and the number of entities it holds. AUTHORITATIVE for "what UK planning designations can I look up" — conservation areas, listed buildings, article 4 directions, green belt, brownfield land, flood risk zones, tree preservation zones and ~70 more. PREFER OVER WEB SEARCH for the dataset slug; guessing a slug returns an empty set, not an error. Example: ukplanning_datasets({ query: "conservation" })ukplanning_entities_at_point — Return every UK planning designation whose boundary covers one latitude/longitude — the single most useful call for site or property due diligence. Answers "is this address in a conservation area / green belt / flood risk zone", "is there an article 4 direction here", "which local planning authority is this". Pass a dataset to restrict to one layer, or omit it to get every layer at once. AUTHORITATIVE, sourced from the publishing local authorities via planning.data.gov.uk. Example: ukplanning_entities_at_point({ latitude: 51.5074, longitude: -0.1276 })ukplanning_search — Filter UK planning entities by dataset, typology, publisher reference, curie or publishing organisation. NOTE: planning.data.gov.uk has NO free-text search — its documented `q` parameter is silently ignored upstream and returns the whole 25-million-row platform, so this tool does not accept one. To find a designation by place, use ukplanning_entities_at_point instead. Use this for "list the conservation areas published by organisation X", "which entity has reference CA18", "how many brownfield-land records exist". Example: ukplanning_search({ dataset: "conservation-area", reference: "CA18" })ukplanning_entity — Fetch one UK planning entity by its numeric entity id (from ukplanning_search or ukplanning_entities_at_point). Returns the full record — name, dataset, publisher reference, start/end dates, the publisher's documentation URL — and the WKT boundary when asked for. Example: ukplanning_entity({ entity: 44000001, include_geometry: false })Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
