Publishing workflows for Hermes
Hermes is a natural fit for fast delegation: ask for a report, a draft sequence, a scheduling pass, or a channel check. Postly supplies the tools and guardrails that make those actions useful for real content teams.
Check publishing activity before a weekly standup.
Try: “Summarize what published this week and what is still queued.”
Create analytics summaries and next-step recommendations.
Try: “Generate a client-friendly performance update using connected analytics.”
Before a write action, confirm content, media, workspace, destinations, date, time, and timezone. Use team approvals where required. Keep the returned post ID and inspect its destination status; accepted or scheduled does not mean published.
Scheduled agent runs depend on your assistant’s orchestration. For recurring source-based publishing, use Auto Post. Your editor and calendar remain available throughout.
Connection and publishing help
No Postly tools appear
Check the endpoint and connection method, enable the tools, and start a fresh session. Client plans and administrator settings can affect custom MCP access.
The workspace or channel is missing
Check the allowed workspace named in the error. Use its workspace ID, switch to the correct API key, or edit Workspace access in API keys. Reconnect a channel if its provider authorization expired.
An accepted request has not published
Retrieve the Postly post ID and inspect the schedule, approval state, and destination results. Resolve the specific validation or provider error before retrying.
How do I stop the connection?
Disable the client connection and revoke its API key in Postly. Review scheduled posts separately; revoking a key does not cancel already accepted publishing work.
