System Locale

URI: system://locale

Configured locale settings (LANG, LC_*).

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 system://locale

Output:

Source: /etc/default/locale
LANG=C.UTF-8

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": "system://locale"}}'

Response:

{
  "jsonrpc": "2.0",
  "id": "35",
  "result": {
    "contents": [
      {
        "mimeType": "text/plain",
        "text": "Source: /etc/default/locale\nLANG=C.UTF-8",
        "uri": "system://locale"
      }
    ]
  }
}
