DMI Hardware Info

URI: devices://dmi

Desktop Management Interface info (lshw/hwinfo equivalent). Detailed hardware specifications (RAM banks, BIOS, chassis).

Example

Every example below shows the equivalent linuxctl command and the raw MCP JSON-RPC call it resolves to. The raw call always follows the same two-step pattern (see MCP API overview for the full explanation): open an SSE stream to get a one-time POST endpoint, then POST the JSON-RPC request there - the result streams back on the SSE connection.

linuxctl

linuxctl resource devices://dmi

Output:

Error: DMI data not available on this system
 (Code: -32603)

curl (raw MCP JSON-RPC)

curl -N -s --cacert mcpd.crt -H "Authorization: Bearer $MCP_TOKEN" https://localhost:9091/sse &
# server sends: event: endpoint / data: /message?session_id=...

curl -s --cacert mcpd.crt -X POST "https://localhost:9091/message?session_id=<from step 1>" \
  -H "Authorization: Bearer $MCP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": "1", "method": "resources/read", "params": {"uri": "devices://dmi"}}'

Response:

{
  "jsonrpc": "2.0",
  "id": "d1",
  "error": {
    "code": -32603,
    "message": "DMI data not available on this system\n"
  }
}
