archive_post
Archive a Postlyra post
Use when the author asks to archive a post and cancel its pending publications. Already delivered Telegram messages stay available. Restore later with restore_post.

attach_media
Attach uploaded media to a post
Use when adding a finalized owner mediaId to a working post. Read the post revision first. Images, videos, audio and voice become media blocks; documents become file blocks. Does not publish or change existing delivery snapshots.
Input schema
{'type': 'object', 'required': ['postId', 'mediaId', 'expectedRevision'], 'properties': {'postId': {'type': 'string', 'maxLength': 128, 'minLength': 1}, 'mediaId': {'type': 'string', 'maxLength': 128, 'minLength': 1}, 'expectedRevision': {'type': 'integer', 'minimum': 1}}, 'additionalProperties': False}

attach_media_to_draft
Attach media to a Postlyra draft
Use this when adding images without changing draft text. Pass mediaFile1..mediaFile6 or mediaFiles: six total, JPEG/PNG/GIF/WebP, 10 MiB each. Exact placement uses update_post_draft with richDocument slot bindings. Returns JPEG and enables a public preview link. Display the image in the FINAL answer via native attachment or display.imageMarkdown. On error follow nextAction. May fetch external image URLs during import or screenshot rendering. Never publishes.

publish_post
Publish a Postlyra post
Use this when the user explicitly authorizes publishing a reviewed existing Postlyra rich draft to a connected Telegram channel. Resolve channelId using list_channels, inspect preview_post, and supply confirmed=true plus confirmationText containing the user's authorization. Reuse idempotencyKey on retry. Queued/retrying means pending, not delivered. This is the external publication action; draft tools never send.

search_post_drafts
Search Postlyra drafts
Use this when finding an existing draft by topic, title or content. Search first when draftId is unknown; do not ask for a link. Matches all keywords/fragments in title and rich text, ignoring case. Empty query lists recent drafts. Follow nextCursor while hasMore. For an in-chat card, pass the returned draftId as postId to show_post_card; use preview_post for a screenshot/browser preview. Returns owner-only IDs and snippets. Never edits, enables sharing or publishes.

show_post_card
Show a Postlyra post in chat
Use this when the author asks to show a post card inside the chat or choose publication controls there. After search_posts or search_post_drafts, pass the found post ID as postId. Renders the MCP Apps UI with preview, text editing and scheduling. A screenshot or preview_post URL is not this UI. Opens no public link and never publishes or schedules on its own.
