Postlyra is an MCP server with 32 tools an agent can call, among them apply_post_to_publication, archive_post, attach_media. It answers at https://postlyra.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Manage Telegram drafts, media, schedules and publications from AI clients.
Description as the publisher wrote it.

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 Inputs: channelId, category |
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 Inputs: draftId |
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 co Inputs: draftId, channelId, confirmed, confirmationText, idempotencyKey |
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. Inputs: publicationId, scheduledAt |
restore_post | Use when restoring an archived Postlyra post as a working draft. Previously canceled publication jobs are not restarted. Inputs: postId |
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. Inputs: postId, channelId, scheduledAt, timezone, expectedRevision, idempotencyKey |
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 n Inputs: query, limit, cursor |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://postlyra.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.prof-1t. Endpoint host: postlyra.app. ARD identifier: urn:air:io.github.prof-1t:mcp:postlyra-mcp.
First indexed 11 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
