Ask in plain English, get real planning records
Your assistant searches by postcode and radius, council, keyword, status and date, opens any application, reads its conditions and checks your allowance. It answers with the council's reference, address, proposal, dates and decision, so you can act on it straight away.
"Find approved loft conversions within 2 km of SW11 1AA decided this month."
"Show me every new application in Camden since Monday that mentions a basement."
"What conditions were attached to the approval of 2026/1234/P in Camden?"
"Who is the agent on that application, and how do I reach them?"
"Which councils do you cover?"
"How many records have I got left this month?"
Works with Claude and the tools you already use
Planning Signal is a remote MCP server at https://www.planningsignal.co.uk/mcp. Copy your key from the API page into one of the snippets below, in place of the example key.
Claude Code
Run one command in your terminal, then ask away.
claude mcp add --transport http planning-signal https://www.planningsignal.co.uk/mcp \
--header "Authorization: Bearer ps_live_your_key_here"Claude Desktop
Add this to claude_desktop_config.json (Settings, Developer, Edit config) and restart Claude. It runs the mcp-remote bridge, so you need Node.js installed.

Add a remote MCP server in your editor's MCP settings with this URL and header. The same works in any client that connects to remote servers and lets you set a header.

}Start free on the demo key
Your assistant runs on the same plans as the planning data API. Create a free account and your demo key comes with 100 records, no card needed. When you want more, an API plan gives you a monthly allowance, shared across your keys and with your own API calls, at 60 requests a minute.
AI assistant questions
Which plan do I need?
Any API plan, starting with the free demo key (100 records, no card). Searching and reading applications works on every plan. Conditions and agent contact details come with API Pro, the Leads website plan and National.
Does it use my API allowance?
Yes, exactly like the API. Each application or condition your assistant returns counts as one record, and the same record again in the same month is free. Listing councils and checking your usage are always free.
Is the data live?
Your assistant searches the same database as the website and the API, updated every day from council planning registers, so it answers with today's applications and decisions.
Can my whole team use it?
Yes. Paid API plans allow up to 5 keys on one allowance, so each person can connect their own assistant with their own key and you can revoke any of them on its own.
Using Planning Signal from an AI assistant is covered by the API & Data Licence, the same terms as the API. Keep your key out of shared config files and screenshots, and revoke it on the API page if it leaks.
Building your own integration? The planning data API gives you the same data as JSON.
