makelaar-mcp

Your AI makelaar (real estate agent) for the Dutch housing market. Search funda.nl, compare listings, calculate Dutch mortgages, and estimate buying costs — all from Claude.

Quick start

Prerequisites: Install uv (Python package runner) if you don't have it:

curl -LsSf https://astral.sh/uv/install.sh | sh

Claude Code

claude mcp add makelaar -- uvx makelaar-mcp

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "makelaar": {
      "command": "FULL_PATH_TO_UVX",
      "args": ["makelaar-mcp"]
    }
  }
}

Replace FULL_PATH_TO_UVX with the output of which uvx (e.g. /Users/you/.local/bin/uvx). Claude Desktop doesn't inherit your shell PATH, so the full path is required.

Then restart Claude Desktop.
