Our reading of HardwareMCP, from the data

HardwareMCP is a iot & home automation MCP server from saadvz, listed in the official MCP Registry.

Its 4 tools add about 470 tokens to every model turn (measured 2026-10-19).

Maintenance is active: the last public signal was 2 days ago (2026-10-16). For comparison, 64% of iot & home automation servers are active or maintained.

With 0 GitHub stars it ranks #64 of 107 iot & home automation servers we index.

It runs as a hosted endpoint, so there is nothing to install.

Install HardwareMCP MCP server

claude mcp add --transport http hardware https://hardwaremcp.khanex.ai/mcp

{
  "mcpServers": {
    "hardware": {
      "url": "https://hardwaremcp.khanex.ai/mcp"
    }
  }
}

{
  "mcpServers": {

      ]
    }
  }
}

Or add it as a custom connector under Settings → Connectors. The config above bridges via mcp-remote.
