MCP server for Zyfy — UK postcode and vehicle intelligence for Claude and other AI agents

VerifiedSTDIODesktop onlyLocation & LifestyleData & Analytics

Overview

AI-generated overview

Local MCP server giving AI assistants UK postcode and vehicle intelligence from the Zyfy API, including flood risk, crime, property prices, MOT and ULEZ data.

What you can do
  • Look up a UK postcode for flood risk, crime rate, broadband coverage, average property price, deprivation index and MP details
  • Look up a UK vehicle registration for make, MOT history, tax and MOT status, ULEZ compliance, safety score and odometer trend
  • Find the nearest postcode to a latitude/longitude coordinate with full enrichment data
  • List all postcodes within a radius of a coordinate, each with full enrichment data
When to use it
Useful when you want to ask natural-language questions about UK addresses and vehicles — property due diligence, flood or crime context for a postcode, or checking a car's MOT, tax and ULEZ status — without writing code.
Requirements
Node.js 18 or later and a local MCP client such as Claude Desktop, Claude Code or Cursor. A Zyfy API key is required, passed as the ZYFY_API_KEY environment variable; the free tier includes 100 requests per month. Network access to the Zyfy service.
Before you install
The API key is a secret placed in client configuration files; the README warns not to commit .mcp.json containing it and to add it to .gitignore. Each tool call consumes quota units, and postcodes_within consumes one unit per postcode returned, so wide radius searches can drain a plan quickly. Queries and coordinates are sent to the Zyfy service.

Installation

In SourceWeft

  1. Open Zyfy Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MCP server for Zyfy — UK postcode and vehicle intelligence for Claude, Cursor, and other AI agents.

Add this server to Claude Desktop, Claude Code, or Cursor and ask natural language questions about UK postcodes and vehicles. No code required.

Prerequisites

  • Node.js 18 or later
  • A Zyfy API key — sign up free at zyfy.uk (free tier includes 100 requests/month). Your key will look like ea_live_....

Setup

Claude Desktop

Add to your Claude Desktop configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json
json
{  "mcpServers": {    "zyfy": {      "command": "npx",      "args": ["-y", "@zyfy-uk/mcp"],      "env": {        "ZYFY_API_KEY": "ea_live_your_key_here"      }    }  }}

Restart Claude Desktop after saving the file.

Claude Code

Add a .mcp.json file in your project root:

json
{  "mcpServers": {    "zyfy": {      "command": "npx",      "args": ["-y", "@zyfy-uk/mcp"],      "env": {        "ZYFY_API_KEY": "ea_live_your_key_here"      }    }  }}

Note: Do not commit .mcp.json if it contains your API key — add .mcp.json to your .gitignore.

For a global setup (applies to all projects), add the same block to ~/.claude.json instead.

The same .mcp.json format works in Cursor and any other MCP-compatible client.

Available tools

ToolDescription
lookup_postcodeFlood risk, crime rate, broadband coverage, average property price, deprivation index (IMD), and MP details for any UK postcode
lookup_vehicleMake, MOT history, tax/MOT status and expiry, ULEZ compliance, safety score, and odometer trend for any UK vehicle registration
nearest_postcodeFull enrichment data for the nearest postcode to a lat/lon coordinate
postcodes_withinAll postcodes within a radius of a lat/lon coordinate, each with full enrichment data

See zyfy.uk/docs for the full response schema and signal reference.

Example prompts

  • What's the flood risk at SW1A 2AA?
  • Is AB12 CDE ULEZ compliant, and when does its MOT expire?
  • What's the average property price and crime rate for the postcode nearest to 51.5074, -0.1278?
  • List all postcodes within 500 metres of 51.5, -0.1 and their flood risk bands.

Quota

Each tool call uses one quota unit from your Zyfy account. postcodes_within uses one unit per postcode returned. Your remaining quota is included in every response. See zyfy.uk/pricing for plan details.

When your quota is exhausted, tools return a message with the reset date and a link to upgrade. When you hit the per-minute rate limit, tools return a message with how many seconds to wait.

If a response includes "enrichmentPending": true, Zyfy is still processing that record in the background. The result contains the best available data — retry in a few seconds for a complete result.
