Planning history at a property
property_planning_historyPlanning history AT this property: applications linked to the unit or its building — each with decision, dates, appeal, CIL liability, development type and `match_level` (`unit`, `building`, or `nearby` within 25 m when nothing is linked) — a summary (approved / refused / withdrawn / pending), what needs consent here from the designation flags read three-valued (`applies` against `unchecked`), the LPA, and `coverage`: official planning data covers the 33 London boroughs today, so `status: not_covered` outside London is a different answer from `no_applications`, and is not charged. UK only.

FAQ
Questions about property_planning_history
How much does `property_planning_history` cost?
+
property_planning_history costs 1 credit per successful call over MCP and over REST, and the two surfaces share one credit balance. The price covers licensed records in the response. A call that fails is not charged.
Do I need to resolve the address first?
+
Yes. property_planning_history takes a UPRN, not an address. Start with address_autocomplete (free) to narrow the address, then address_resolve (8 credits) to get the UPRN. An assistant with the MarketCode skills installed does both steps on its own.
Which assistants can run `property_planning_history`?

Any MCP client: Claude (claude.ai, Claude Desktop, Claude Code), ChatGPT in developer mode, Codex and Cursor, each documented on the MCP page. You sign in with your MarketCode account over OAuth; there is no key to paste, and the connection is read-only.
Where does the data come from?
+
The answer is computed by MarketCode. Coverage is the UK.
Can I store or republish the results?
+
The response includes records we license. Use them in your own analysis, reports and products; bulk redistribution of the raw records or building a competing dataset from them is not covered. Ask us if you need a redistribution licence.
Does `property_planning_history` change anything?
+
No. The tool is annotated read-only on the server, so it never writes to your data or ours and an assistant can call it without a confirmation step.
