"""Dependency-free, host-neutral stdio MCP facade for BJD CMS content work.

All API traffic goes through the canonical skill helper so host allowlisting,

token redaction, endpoint whitelisting, idempotency, and semantic response
|
||
checks stay in one place. The facade adds typed read, preflight, and guarded
|

write workflows without depending on any one agent host's conversation API.
