Nothing serious here today

Today is the operative word: we check Postlyra every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 32

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

post
create_post_draft
Use this when creating a Telegram draft. Read get_formatting_capabilities; prefer finished richDocument, which overrides text/preset/template. Bind mediaFile1..mediaFile6 or mediaFiles slots as media.src. Returns draftId, JPEG and public preview link. Display the image in the FINAL answer via native attachment or display.imageMarkdown. Inspect preview_post. May fetch external image URLs during import or screenshot rendering. Never publishes.
get_post
Use when reading an existing post and its current revision before editing. Returns the working document without enabling a public preview or publishing anything.
search_post_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.
update_post
Use when changing a post's working content, title, buttons or attention flag. Read its revision first. Scheduled and sent messages remain on their own snapshots until apply_post_to_publication is requested.
update_post_draft
Use this when editing a draft. Read preview_post and get_formatting_capabilities. Send the complete edited richDocument, preserving untouched content and media; text replaces layout. Bind imported file slots as media.src. Returns JPEG and enables a public preview link. Display the image in the FINAL answer via native attachment or display.imageMarkdown. Inspect preview_post. May fetch external image URLs during import or screenshot rendering. Never publishes.
template
create_template
Use when the author asks to save a reusable post layout. Supply a name and RichDocument. Creates an owner-only template without publishing.
delete_template
Use when the author asks to delete their saved template. Existing posts made from it are preserved.
update_template
Use when changing the author's saved template. System templates and other users' templates cannot be edited.
attach
attach_media
Use when adding a finalized owner mediaId to a working post. Read the post revision first. Images and videos become media blocks; other files become a link. Does not publish or change existing delivery snapshots.
attach_media_to_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.
workspace
get_workspace
Use when checking publication quotas, storage, connected chat count or the account time zone before planning content.
update_workspace
Use when the author asks to change the account time zone, weekly publication target or content reminder preference. Does not change existing publication times.
apply
apply_post_to_publication
Use when the author explicitly asks to apply a working post revision to one selected scheduled or delivered Telegram publication. Other destinations stay unchanged. Read the post revision and publicationId first.
archive
archive_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.
auth
get_auth_status
Use this when you need to check whether the current MCP caller is authorized through Telegram and linked to a Postlyra account.
cancel
cancel_publication
Use when the author asks to cancel one pending publication. Preserves the source post and its history. A publication already being sent cannot be canceled.
channels
list_channels
Use this when you need to list Telegram channels, groups, and chats the authorized user can manage through Postlyra.
content
get_content_attention
Use when reviewing unfinished drafts, formatting or media problems, lost publishing permissions, failed deliveries and gaps in the author's publication target. Does not read private Telegram Business conversations or send messages.
copy
copy_post
Use when reusing an existing post as a new independent draft. Copies formatting, media and buttons; does not copy publication jobs or publish.
finalize
finalize_media_upload
Use after uploading bytes to the URL from create_media_upload. Verifies file content, size and ownership and returns a durable mediaId for attach_media. Expired or invalid uploads are rejected.
formatting
get_formatting_capabilities
Use this when composing or formatting any Postlyra post: call it FIRST, once per task. Postlyra creates beautifully structured rich Telegram posts, illustrated instructions, articles and presentations. Returns the complete RichDocument contract: exact JSON examples for every block and inline mark, nesting, limits, file uploads, error recovery, presets and which tool to use next. Use this contract for formatting; Telegram MarkdownV2/parse_mode documentation is not needed.
media
create_media_upload
Use when uploading a local image, video or document from any MCP client. Returns a short-lived PUT URL, headers and uploadIntentId. Upload the actual bytes, then call finalize_media_upload. A local filesystem path cannot be read by the server.
posts
search_posts
Use when finding any existing Postlyra post, including scheduled, published or archived content. Search owner content by words, status, connected channel and update dates. Read the selected post with get_post.
preview
preview_post
Use this when requesting a saved draft screenshot, public browser preview or validation warnings. Find draftId with search_post_drafts. Returns documentJson/richHtml, JPEG and enables a public preview link. Use show_post_card for an in-chat card. Follow display.instruction; check screenshot.truncated and retry unavailable screenshots without recreating the draft. May fetch external image URLs for screenshot rendering. Never publishes.
publication
delete_publication
Use only when the author explicitly asks to delete one message previously published by Postlyra. Supply its publicationId. The source post and messages in other destinations remain available.
publications
list_publications
Use when inspecting scheduled publications, delivery failures or messages previously published by Postlyra. Returns publicationId for rescheduling, cancellation, targeted edits or deletion.
publish
publish_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.
reschedule
reschedule_publication
Use when the author asks to change the date or time of one pending publication. Supply its publicationId and a concrete ISO date with UTC offset. Does not change its content.
restore
restore_post
Use when restoring an archived Postlyra post as a working draft. Previously canceled publication jobs are not restarted.
schedule
schedule_post
Use when the author explicitly asks to schedule a post to a connected channel or group. Supply an exact ISO date with UTC offset and an idempotency key. The server uses the shared publishing rules and stores an immutable delivery snapshot.
show
show_post_card
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. If unavailable, refresh the connection's tool metadata; clients without UI retain text/tool workflows.
templates
list_templates
Use this when the user wants an existing reusable Postlyra layout template. Optional for custom composition. For supported blocks, JSON syntax or formatting choices call get_formatting_capabilities; this tool lists saved templates and their ids.

Postlyra — questions

Answers built from our own checks of this server.

What can Postlyra do?
It exposes 32 tools, read directly from the server on our last check. Among them: apply_post_to_publication, archive_post, attach_media, attach_media_to_draft, cancel_publication, copy_post and 26 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Postlyra mostly used for?
Its tools cluster around post, template and workspace. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Postlyra working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 154 ms. The bar chart above shows every period we have measured.
How do I connect Postlyra?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Postlyra need an API key?
No. Postlyra completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 32 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Postlyra?
It answers our handshake in 154 ms on average, which is faster than 76% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Postlyra open source?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
