How do I install the Homedata MCP in Claude Desktop?

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

Add to

~/Library/Application Support/Claude/claude_desktop_config.json

macOS — Linux uses ~/.config/Claude/, Windows uses %APPDATA%\Claude\.

Recommended for Claude Desktop — 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"
      }
    }
  }
}
Restart Claude Desktop after saving. Your new MCP server appears in the slider menu next to the chat input.

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 Claude Desktop:

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 Claude Desktop

Restart Claude Desktop after saving. Your new MCP server appears in the slider menu next to the chat input.

CLI quickstart — homedata commands for Claude Desktop users

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

Claude Desktop + Homedata MCP — frequently asked questions

How do I install the Homedata MCP in Claude Desktop?
Install the homedata-mcp Python package with pip install homedata-mcp, then open Claude Desktop, go to Settings → Developer → Edit Config, and add the homedata block to mcpServers. Drop in your free Homedata API key, save the file and restart the app. Claude will show homedata as a connected MCP server.
Does the Homedata MCP work with Claude Desktop on Windows and Linux?
Yes. The same Python package runs on macOS, Windows and Linux. The only difference is the path to claude_desktop_config.json — macOS uses ~/Library/Application Support/Claude/, Linux uses ~/.config/Claude/, Windows uses %APPDATA%\Claude\.
Do I need a paid Claude plan to use the MCP?
No. The Homedata MCP works with any Claude Desktop install — free, Pro or Team. The MCP server runs locally on your machine; Anthropic never sees the property data you query.
Where does the property data come from?
Homedata aggregates official UK sources — the EPC register, Environment Agency, Land Registry, ONS census, Ofsted, Home.co.uk and more — across 29 million UK properties. Every MCP tool maps to a typed endpoint on the public Homedata API.
Does the Homedata MCP work with the free tier?
Yes — the free Homedata tier (no credit card required) works in Claude Desktop as soon as you paste your API key into HOMEDATA_API_KEY. Higher-tier plans unlock larger monthly quotas and the property sales, listings and comparables tools.
Should I install the Python or Node edition for Claude Desktop?
Pick Node for Claude Desktop — 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 Claude Desktop 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 Claude Desktop.
