# Grundheim MCP — Swiss real estate tools for AI assistants

[Grundheim](https://www.grundheim.ch) runs an open [MCP](https://modelcontextprotocol.io) server that gives AI assistants authoritative Swiss real-estate answers — computed by the same engines that power grundheim.ch, instead of estimated.

**Endpoint:** `https://agent.grundheim.ch/mcp` (streamable HTTP, no authentication, read-only)

## Install as a Gemini CLI extension

```bash
gemini extensions install https://github.com/ParetoLabsCH/grundheim-mcp
```

## Use with other MCP clients

The same endpoint works everywhere MCP does:

```bash
# Claude Code
claude mcp add --transport http grundheim https://agent.grundheim.ch/mcp
```

- **Claude (claude.ai)** — Settings → Connectors → Add connector → paste the endpoint URL
- **ChatGPT** — Settings → Connectors (developer mode) → New connector → paste the endpoint URL
- **Gemini app** — Settings → Connected apps → Add custom app (requires Google AI Ultra)
