Upload Post tools 57
upload_videoPublish a video to one or more platforms. Use `videoPathOrUrl` only for public/signed HTTPS URLs, or for absolute local paths when the MCP server runs on the same machine as the file. `videoBase64` is only for clients that can provide raw bytes directly and is capped by UPLOAD_POST_MAX_INLINE_MB (default 100). Returns a `request_id` you can poll with `get_status`. Supports per-platform overrides (tiktokPrivacyLevel, youtubePrivacyStatus, youtubePlaylistId, youtubeThumbnailUrl, youtubeTags, facebookPageId, instagramMediaType, etc.). Reddit posting is currently unavailable (error_code=reddit_unavailable) until the Reddit app is restored. Do not use reddit as a publish target. A hosted MCP server cannot read files on the user's machine or chat attachments (`/mnt/data`, sandbox paths). To publish a local file: (1) if this client can run HTTP requests itself (for example a coding agent with a shell), stage it with `create_media_upload` (returns `upload_id` + `upload_url`), PUT the raw file bytes to `upload_url` with the same Content-Type, call `complete_media_upload` and pass the returned `media_url` as the media URL; (2) otherwise ask the user for a public HTTPS URL of the file, or tell them to publish it from the dashboard at https://app.upload-post.com. Staged media is deleted after 24 hours.upload_photosPublish one or more photos (single image or carousel). Each item in `photosPathsOrUrls` may be a public URL or a local path. Reddit posting is currently unavailable (error_code=reddit_unavailable) until the Reddit app is restored. Do not use reddit as a publish target.upload_textPublish a text-only post. `linkUrl` (or platform-specific *LinkUrl) attaches a link preview where supported. Reddit posting is currently unavailable (error_code=reddit_unavailable) until the Reddit app is restored. Do not use reddit as a publish target.upload_documentPublish a document (PDF / PPT / PPTX / DOC / DOCX) to LinkedIn. Title is required.get_statusCheck the status of an async upload by `request_id`. Poll this until `status` is 'success' or 'failed'.get_job_statusCheck the status of a scheduled or queued upload by `job_id`. Use this for posts created with `addToQueue` or `scheduledDate`.get_historyPaginated history of uploads across all profiles.get_mediaRetrieve recent media (videos, photos, text posts) pulled directly from a profile's connected social accounts. Supports instagram, tiktok, youtube, linkedin, facebook, x, threads, pinterest, bluesky, reddit. Useful for browsing what already exists on a platform before posting more. Paginated: the response carries `pagination` = { limit, next_cursor, has_more }; pass `next_cursor` back as `cursor` for the next page (the last page returns next_cursor null and has_more false).list_scheduledList all currently scheduled (not-yet-published) posts.cancel_scheduledCancel a scheduled post by its `job_id`.edit_scheduledEdit a pending scheduled post in place, keeping its job ID and media: reschedule it (scheduledDate/timezone) and/or fix its text. `title` and `caption` rewrite the text for EVERY platform of the post; to change only some platforms, send `platformContent` instead, e.g. {"instagram":{"caption":"..."},"tiktok":{"caption":"..."}} — platforms not listed keep their text. First comments cannot be edited on a pending post.get_analyticsAggregated analytics for a profile across selected platforms (followers, views, engagement). Instagram also returns two audience breakdowns with the same shape (age / gender / country / city): `follower_demographics` for the account's followers and `engaged_audience_demographics` for the accounts that engaged with its content.- +45 more on the listing page
