Feature & Specification Comparison
Tools & Capabilities Breakdown
Content Distribution MCP Tools (8)
post_publish
Publish one or more channel variants immediately. Side effects: makes external HTTP requests to each channel platform; writes publish state to the local YAML backend; requires valid credentials in the named profile. Idempotent on (content.id, channel) — re-running with the same IDs returns cached state without re-posting. Use post_publish for immediate-only delivery; use post_schedule when any variant needs a future schedule_at; use post_drain to flush a previously built queue.
post_schedule
Enqueue channel variants with schedule_at for future publishing; variants without schedule_at are published immediately. Side effects: writes entries to the local YAML schedule store; makes external HTTP requests for any immediately-published variants; requires credentials in the named profile. Idempotent on (content.id, channel). Use post_schedule when any variant needs a future publish time; use post_publish for all-immediate delivery; use post_drain to process the scheduled queue later.
post_drain
Fire all scheduled posts due at or before the given time boundary. Side effects: makes external HTTP requests for each due entry; writes results to the YAML backend. Idempotent — already-published (content.id, channel) pairs are skipped; no-op when no entries are due. Safe to call from cron. Use post_drain on a recurring schedule to flush the queue; use post_publish or post_schedule to add new content; use post_status to inspect results after drain runs.
