UK property data MCP server for Cline (VS Code)

VS Code extension by the Cline team — autonomous coding inside your editor. Install the Homedata MCP and Cline gains typed tools for 29 million UK properties — EPC, flood risk, planning, schools, transport — answered straight from your chat or agent. Ships as a Python package or a Node package; pick whichever fits Cline best.

How do I install the Homedata MCP in Cline?

Three steps: install the homedata-mcp package (Python or Node), drop in the config block, restart Cline.

Add to

VS Code → Cline → MCP Servers → Edit MCP Settings

Cline stores MCP config under VS Code globalState. Edit it via the Cline panel — manual JSON editing is also supported.

Recommended for Cline — runs via npx, no global install needed. Node 18+ required.

{
  "mcpServers": {
    "homedata": {
      "command": "npx",
      "args": ["-y", "homedata-mcp"],
      "env": {
        "HOMEDATA_API_KEY": "your_api_key_here"
      }
    }
  }
}
Click "Save" in the Cline MCP Settings panel. The homedata server appears in the MCP Servers list once registered.

Either edition exposes the same MCP tools and the same homedata CLI. Pick Node if you want zero-install via npx; pick Python if your AI client already embeds Python.

1. Install the server

Pick the runtime that fits Cline:

Python (pip)
pip install homedata-mcp
Node (npm / npx) Recommended
npm install -g homedata-mcp
# or zero-install via npx:
npx -y homedata-mcp

2. Get your API key

Sign up and copy your key from the developer dashboard. Paste it into HOMEDATA_API_KEY.

3. Restart Cline

Click "Save" in the Cline MCP Settings panel. The homedata server appears in the MCP Servers list once registered.

CLI quickstart — homedata commands for Cline users

The same package ships a homedata CLI on your PATH. Useful for one-off lookups, shell scripts, or piping property data back into Cline as context.

Install the CLI

Same homedata command in both editions.

Python (pip)

pip install homedata-mcp

Node (npm)

npm install -g homedata-mcp

Or run once, no install

npx -y homedata-mcp homedata --help
Set HOMEDATA_API_KEY in your shell before running any command — same key as the MCP server.

What can Cline ask about UK property?

Typed tools Cline gains the moment the Homedata MCP is connected. Each tool has its own anchor — link directly to #tool-lookup-epc, #tool-lookup-flood-risk and the rest.

Find UK addresses from free text: an address, a postcode or a place name. Returns matching addresses with their UPRN, which every property tool takes.

The cheap first call for a property: which data is available for it, what each add-on costs, and the shortcuts to each tier. Also the quickest way to check whether a UPRN is one we hold.

Address-only record for a property: full address, postcode, coordinates and the standard address identifiers. The cheapest property tier, for address verification, form pre-fill and matching.

The house-hunter view of a property: address, rooms, EPC rating, last sale, construction, dimensions, garden, parking and title basics, in one call.

The full listing view of a property: everything in Base plus council tax band, flood risk, schools, broadband, crime, demographics, solar potential, confirmed sales and planning constraints. The usual starting point.

Everything held on a property in one call: the Core record plus the full council tax charge, full title, environmental risks, deprivation, planning history and area price trends.

Build your own property record: the base record plus only the add-ons you ask for, so you pay for exactly what you use. Call property_discovery first to see which add-ons a property has.

attr_rooms Included

Room counts for a property: bedrooms, bathrooms, habitable rooms and heated rooms.

Environmental risk screening for a property: flood, radon, noise, landfill, coal and other mining, invasive plants and air quality. Ask for one hazard, or for all of them in a single response.

Cline + Homedata MCP — frequently asked questions

How do I add the Homedata MCP to Cline?
Open the Cline panel in VS Code, click the MCP Servers icon, choose 'Edit MCP Settings' and paste the homedata block from this page into the JSON. Save the file — Cline reconnects automatically and the homedata tools appear in the Available Tools list.
Does Cline auto-approve tool calls?
Cline asks for approval before each tool call by default. You can enable auto-approval per tool — useful for repeated lookups like address_find that have no side effects.
Can I use Cline with the Homedata MCP and a local LLM?
Yes. Cline supports any chat model — Claude, GPT-4, local via Ollama. The MCP server runs independently of the model, so a local 70B can use the same homedata tools as a hosted Claude.
Does the Homedata MCP work on a pay-as-you-go account?
Yes — Homedata works in Cline as soon as you paste your API key into HOMEDATA_API_KEY. Every tool is available to every account, including property sales, listings and comparables — each call spends its token weight (100 tokens = £1).
Should I install the Python or Node edition for Cline?
Pick Node for Cline — npx -y homedata-mcp gives you zero-install setup. The Python edition is equivalent if you'd rather pip install once and avoid Node entirely.
How does the homedata CLI differ from the MCP server?
Both ship in the same package. The MCP server is what Cline talks to over the Model Context Protocol — typed tools, structured JSON. The homedata CLI is for humans — same data, but invokable as `homedata property`, `homedata epc`, `homedata flood-risk` directly in a terminal. Useful for piping into shell scripts or back into Cline.
