plannexus-mcp

Put UK planning data inside your AI. plannexus-mcp is an MCP server that lets Claude, ChatGPT or any MCP client query PlanNexus — planning applications across ~363 UK local planning authorities — in plain English.

Ask things like "what's been applied for within 500m of SW1A 1AA this month?" and your assistant calls PlanNexus directly.

Tools

Tool	What it does
`search_applications`	Search by free text, postcode, council, or lat/lng + radius, with type/status/date filters
`get_application`	Full detail for one application — status, decision, dates, and (on a paid plan) agent / applicant / case-officer contacts
`get_constraints`	Planning constraints at a postcode or point — conservation area, listed building, Article 4, TPO, flood, green belt, …
`find_authority`	Look up a council's id by name

Setup (Claude Desktop)

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "plannexus": {
      "command": "uvx",
      "args": ["plannexus-mcp"],
      "env": { "PLANNEXUS_API_KEY": "pn_live_..." }
    }
  }
}

Restart Claude and ask away. Search works without a key (public preview); add a PlanNexus API key to unlock applicant/agent contacts on a paid plan.

Run directly

PLANNEXUS_API_KEY=pn_live_... uvx plannexus-mcp

PLANNEXUS_BASE_URL overrides the API base (defaults to https://api.plannexus.io/v1).
