"""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.
