Overview

AI-generated overview

Hosted MCP service that lets an AI assistant draft, preview, schedule and publish rich posts to connected Telegram channels and groups.

What you can do
  • Create, search, read, update, copy, archive and restore Telegram post drafts with rich formatting, buttons and media
  • Preview drafts and signatures as screenshots or public read-only links, and show in-chat post cards
  • Upload local images, video, audio and documents through short-lived upload URLs and attach them to posts
  • Schedule, reschedule, cancel, edit or delete publications on connected channels and groups
  • Manage reusable auto-signatures and layout templates, and check workspace quotas, storage and time zone
When to use it
Useful when you write and publish Telegram content and want an assistant to compose structured posts, review previews, and schedule or publish them to named channels under your approval. Also fits teams that reuse templates and auto-signatures across several channels.
Requirements
A remote Streamable HTTP endpoint; no local install or bot token needed. A Postlyra account signed in with Telegram, OAuth with PKCE authorization in the client, and at least one channel or group connected with @PostlyraBot granted the needed rights. Drafts can be saved before connecting a destination.
Before you install
Publishing, scheduling, rescheduling, canceling and deleting publications change live Telegram content and should only follow explicit user approval. Uploads send file bytes to the hosted service, and previews may fetch external media. Saved signature content is treated as untrusted data. The free beta is capped at 5 channels, 30 publications per day, 300 per 30 days and 1 GB of media, and publications carry mandatory Postlyra attribution.

Installation

In SourceWeft

  1. Open Postlyra in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.prof-1t%2Fpostlyra-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Postlyra MCP

Postlyra.app connects AI chats to Telegram publishing. Create structured drafts, review previews and publish to a named connected channel now or on a schedule. For ChatGPT, install Postlyra from the published plugin directory; for compatible clients, use remote MCP.

Русский · Website · Connection guide

Save Telegram drafts, schedule publications and manage your content from an AI client. Postlyra is a hosted service. This repository contains public integration instructions, client configurations and diagnostics; it does not contain the private SaaS backend. No bot token or locally installed server is required.

Current discovery, checked October 28, 2026: the hosted endpoint reports MCP server version 0.3.6 and exposes 41 tools through tools/list. This includes get_postlyra_guide and eight auto-signature tools for listing, reading, previewing, creating, updating, deleting, converting drafts and assigning signatures. Registry version remains 0.2.0-rc.1; its version is separate from the hosted service. See the release record.

Historical compatibility evidence for hosted MCP 0.3.5. Its discovery snapshot contained 32 tools. Desktop ChatGPT completed draft/card edits, browser source continuity, scheduling/moving/canceling, timed channel delivery and selected-message edit/delete with developer CSP enforcement enabled. The 804-test suite, typecheck/build and documentation checks passed. Group acceptance is blocked by a client safety review; remaining clients/devices are listed in client evidence. See the card guide. Registry version remains 0.2.0-rc.1.

Connect

  • Remote MCP URL: https://postlyra.app/mcp
  • Transport: Streamable HTTP
  • Authentication: OAuth with PKCE, using your Postlyra account.
  1. Open Postlyra and sign in with Telegram.
  2. Add your channel or group under Connections and grant @PostlyraBot the necessary rights. You may save drafts before connecting a destination.
  3. In ChatGPT, install Postlyra from the plugin directory. In other compatible AI clients, add the MCP URL. Follow the OAuth sign-in flow and review the requested permissions.
  4. Ask the client to list your connected channels, then save a test draft. Configuration is complete only after authorization and a successful tool call.

Claude Code

text
claude mcp add --transport http --scope user postlyra https://postlyra.app/mcp

Open /mcp and authenticate Postlyra. Alternatively merge claude-code.json into the project's .mcp.json without replacing other servers. This is a Claude Code configuration, not a Claude Desktop remote-connector configuration. Official Claude Code instructions.

Codex

Merge codex.toml into your Codex config.toml, preserving the existing configuration. Then run codex mcp login postlyra to start the separate MCP OAuth flow. Official Codex instructions.

Cursor

Merge cursor.json into project .cursor/mcp.json or your global Cursor MCP configuration. Open the server settings and complete OAuth. Official Cursor instructions.

ChatGPT

In ChatGPT, open Postlyra in the plugin directory and install it. Connect your Postlyra account through OAuth, sign in with Telegram and review the requested permissions. Ask for your connected channels, save a draft and review its preview. Then explicitly name the channel and authorize publishing; for scheduling, include a date, time and time zone. Availability depends on your account and workspace policy. The published plugin is the primary installation path; it does not require Developer mode.

Claude

Open Customize → Connectors → Add custom connector, enter the public MCP URL and select Connect to authorize Postlyra. Team/Enterprise owners may need to add the connector for their organization first. Claude's remote connection originates from Anthropic's infrastructure, including when using Claude Desktop; use the account connector interface rather than the local desktop-extension configuration. Official Claude instructions.

Example requests

  • “Save this text as a Postlyra draft titled Weekly recap.”
  • “Find my draft about the autumn launch and show it.”
  • “Find my music post and show its Postlyra card.”
  • “Schedule this post in my connected channel for October 22, 2026 at 10:00 Europe/Moscow.”
  • “Move that publication to October 23 at the same local time.”
  • “Apply the current version only to the publication in my news channel.”
  • “Cancel this scheduled publication.”
  • “Show posts that need attention.”

Read permissions, media transfer, troubleshooting and the compatibility record.

Free Beta

5 channels/groups, 30 publications per day, 300 per 30-day period and 1 GB of media. For server-managed connected publications, one known target counts as one publication; technical retries are not additional publications. Native/inline flows use temporary holds and the confirmations available from Telegram, so exact recipient counting is not guaranteed. See confirmation limits. Publications include mandatory Postlyra attribution. AI-client subscriptions are separate.

Drafts and publications are distinct. Saving content does not automatically edit sent messages. Native/inline Telegram shares may lack identifiers required for later message management; the original Postlyra draft remains editable.

Diagnostics

Node.js 18+:

text
node scripts/diagnose.mjs

This makes read-only checks of public metadata and unauthenticated MCP discovery. It does not authenticate, access drafts or publish anything.

Distribution status

server.json is published as io.github.prof-1t/postlyra-mcp, version 0.2.0-rc.1. The official Registry API confirmed an active entry on September 11, 2026. The production endpoint also exposes the expanded tool metadata. Postlyra is also published in the ChatGPT plugin directory. The MCP Registry and ChatGPT directory are separate distribution channels; a listing does not establish independent live validation of every AI client. See the release record.

get_auth_status

Get Postlyra auth status

Use this when checking the verified Telegram account linked to this AI connection. Show its label when introducing Postlyra or resolving missing channels. The bot must be opened under the same account. Chats connected under another account are not visible here.

Takes no parameters.

get_postlyra_guide

Get Postlyra usage guide

Use this when onboarding, resolving publication modes or recovering from errors; call first for onboarding, publication modes in AI chat/browser/Mini App, connecting channels/groups or error recovery. Defaults to a short quickstart; choose topic and level=workflows for steps or reference for examples. Explains IDs, revisions, media, buttons, consent and Free attribution. Public help only: reads no user data and never sends. Use get_formatting_capabilities for full RichDocument syntax.

Parametersleveltopiclocale

get_formatting_capabilities

Get Postlyra 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.

Takes no parameters.

list_channels

List Telegram channels

Use this when you need to list Telegram channels, groups, and chats the authorized user can manage through Postlyra.

Takes no parameters.

list_templates

List Postlyra 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.

ParameterscategorychannelId

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.

Parameterslimitquerycursor

create_post_draft

Create a Postlyra post draft

Use this when creating a Telegram draft. Read get_formatting_capabilities; prefer finished richDocument. Bind mediaFile1..6/mediaFiles via media.src slots. Returns ID, JPEG, preview link and its own card on MCP Apps hosts; do not call show_post_card automatically afterward because it duplicates that card. Keep the link and follow display instructions. Image references/file inputs are validated and imported; direct RichDocument media.src can remain external. Check validation. Never publishes.

ParameterstextstyletopicrequiredlanguagechannelIdstructuremediaFile1mediaFile2mediaFile3mediaFile4mediaFile5mediaFile6+6 more

preview_post

Preview a Postlyra 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.

ParametersdraftIdrequiredchannelId

update_post_draft

Update a Postlyra post draft

Use this when updating a legacy draft or binding file slots. Prefer get_post -> update_post(expectedRevision); never bypass revision_conflict. Send full richDocument preserving untouched content; text replaces layout. Bind media.src to file slots. Returns JPEG/public preview; follow display instructions and validation. Image references/files are imported; arbitrary RichDocument media.src may remain external. Never publishes.

attach_media_to_draft

Attach media to a Postlyra draft

Use this when adding images without replacing draft text: mediaFile1..6/mediaFiles or direct image references[].url, six total, JPEG/PNG/GIF/WebP, 10 MiB each. Inputs are downloaded, validated and imported before success; failure attaches nothing. For exact placement use update_post_draft with richDocument file-slot bindings. Returns JPEG/public preview; follow display instructions, validation and error nextAction. Never publishes.

ParametersdraftIdrequiredmediaFile1mediaFile2mediaFile3mediaFile4mediaFile5mediaFile6mediaFilesreferencesplacementHint

publish_post

Publish a Postlyra post

Use this when publishing a reviewed draft to a connected channel/group, only with explicit user approval. Resolve list_channels and preview_post; confirmed=true and confirmationText quote the actual affirmative authorization, with no magic phrase/language. Optional dryRun=true checks readiness without a job or send. expectedRevision protects against stale content. Reuse idempotencyKey on retry. Pending/uncertain is not delivered. Never invent consent or bypass it with scheduling.
