Overview
Social Post (YouTube, Facebook, Mastodon) via Publora
Creates and schedules posts to YouTube, Facebook Pages, and Mastodon through the Publora MCP server, handling each platform's video/text/format requirements automatically, including cross-posting the same content to all three at once. Use it to publish a video to YouTube, an announcement to a Facebook Page, or a post to Mastodon, individually or all at once. YouTube requires a video for every post; Mastodon is capped at 500 characters and public visibility only.
What it does
Social Post via Publora unifies posting to three platforms that don't need platform-specific complexity: YouTube (video uploads with title, description, and privacy settings), Facebook Pages (text, images, or video - never mixed - to a Page, not a personal profile), and Mastodon (short posts on the mastodon.social instance, federated across the fediverse). A single create_post call can target one platform or several at once, with Publora adapting the same content to each platform's actual requirements - for example splitting a video+caption request into a YouTube upload with title/description and a Facebook post with the same video, while Mastodon only gets the text under its 500-character cap.
When to use - and when NOT to
Use it to publish or schedule a video to YouTube, an announcement or photo set to a Facebook Page, a short update to Mastodon, or the same message across all three simultaneously. Each platform has hard constraints worth knowing before relying on this for a specific post: YouTube requires an actual video file for every post (no text-only or image posts) and only takes one video per post; Facebook only posts to Pages, not personal profiles, and a post can carry images or video but not both; Mastodon is capped at 500 characters with no auto-threading for longer content (unlike X/Twitter) and posts are public by default.
Inputs and outputs
Setup: create a free Publora account, connect each platform via OAuth in the dashboard (Google OAuth for YouTube, requiring a channel; Facebook OAuth for Pages; Mastodon OAuth against mastodon.social), get an API key, and configure an MCP server entry against https://mcp.publora.com. create_post takes a platforms array mixing IDs like youtube-UCxxx, facebook-112233445566, and mastodon-456, content text, and a required scheduledTime; get_upload_url fetches a presigned URL for attaching media by contentType and type; list_posts/update_post/delete_post manage what's already queued. YouTube-specific privacy and title overrides (platformSettings.youtube.privacy / .title) are REST-API-only, not exposed through MCP. Platform limits differ sharply: YouTube allows videos up to 12 hours and 512 MB with 100-character titles; Facebook allows up to 10 images (10 MB each) or a 45-minute video, with post text capped at 2,200 characters on the frontend (63,206 via API); Mastodon caps at 4 images (16 MB each) or a ~99 MB video alongside its 500-character text limit.
Integrations
If MCP is unavailable, the same functionality is reachable over REST at https://api.publora.com/api/v1 using an x-publora-key header. Multiple Facebook Pages each get their own platform ID and can all be posted to in one request. Plan limits are shared across Publora's skills: free Starter allows 15 posts/month, Pro 100/account/month, Premium 500/account/month.
Who it's for
Marketers and creators who publish the same core content - a video, an announcement, a short update - across YouTube, Facebook Pages, and Mastodon, and want one skill to handle each platform's specific requirements instead of three separate posting flows.
