List the children of an element in the Xentara model tree.

Resolve an element's dotted primary-key path to its UUID.

Read an element's name, type, category, quality, and current value.

Get Xentara server information: version, connected username, and model file path.

Write a value to an element's "value" attribute. Disabled unless the operator has explicitly enabled writes (XENTARA_MCP_ALLOW_WRITE=1) — this can change real device/register state on a live Xentara instance.
