### Description (declared)

# google-home-blade-mcp

**Security-first, token-efficient MCP server for Google Home and Nest devices via the Smart Device Management API.**

Control thermostats, stream cameras, monitor doorbells, and pull device events — all through a hardened MCP interface designed for LLM-driven home automation.

## Why This Exists

| | ghome-mcp-server | Google's Cloud MCPs | **google-home-blade-mcp** |
|---|---|---|---|
| **Device coverage** | Smart plugs only | No Google Home MCP | Full SDM: thermostats, cameras, doorbells, displays |
| **Security model** | None | IAM-only | Write gates + confirm gates + credential scrubbing |
| **Token efficiency** | Verbose JSON | N/A | Pipe-delimited, null-omission, ~25 tokens/device |
| **Thermostat control** | No | No | Mode, setpoint, eco, fan — all with safety gates |
| **Camera streams** | No | No | WebRTC/RTSP with 5-min session management |
| **Event streaming** | No | No | Pub/Sub integration for motion, person, doorbell events |
| **Batch operations** | No | N/A | `ghome_status` dashboard, `ghome_thermostats` overview |
| **Marketplace ready** | No | No | `stallari-plugin.yaml`, `home-v1` contract, SKILL.md |

### Design Principles

1. **Security-first** — Every device command requires explicit write enablement. Destructive operations require double confirmation. OAuth tokens never appear in output. Access tokens live in memory only.
2. **Token efficiency** — Compact pipe-delimited output. Null fields omitted. Dashboard views compress entire device fleets into minimal tokens. One `ghome_status` call replaces N individual queries.
3. **Event-driven** — Pub/Sub integration enables webhook-style triggers for motion detection, doorbell presses, and state changes. No polling required.

## Quick Start
