Description

From the marketplace listing

PostWing is a social media scheduling tool for Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, and Threads. Describe the post you want and it shows you the caption, the accounts, and the exact send time. Approve it and PostWing schedules the post to every account at once, so you write once instead of posting one platform at a time. You can also review what is already queued, reschedule or rewrite upcoming posts, and cancel anything before it publishes.

# Schedule social posts with PostWing

PostWing is a remote MCP server. Auth is OAuth: the user signs in to PostWing the first time they use a tool.

## Before scheduling

1. Call `get_me` for the user’s timezone.
2. Call `list_accounts` (optionally with `platform`) to get account ids. If the user has more than one account on a platform, ask which one.
3. If nothing is connected, call `connect_account`, have the user finish the login in their browser, then call `sync_accounts`.
4. For Pinterest, call `list_pinterest_boards` and set `options.board_id`.

## Schedule a post

1. Gather the caption, any media, the accounts, and the time (convert it to ISO 8601 with the user’s timezone).
2. Show the user the caption, each account (platform and handle), the media, and the time, and wait for a clear yes.
3. Call `schedule_post` with `caption`, `scheduled_at`, `accounts: [{ id, caption?, options? }]`, and `media: [{ url, type?, cover? }]`.
4. Tell the user it is scheduled and share `dashboard_url`.

## Edit or cancel

- Find posts with `list_posts` (follow `next_offset` while `has_more`) or `get_post`.
- Change a post with `update_post`, sending only the fields that change. For several posts, call it once per post.
- Cancel: `cancel_post`.
- Show the user the change and get a yes before any of these.

## Media

- Prefer `request_media_upload` for in-chat uploads when the host supports it.
- Or `import_media` with public HTTPS URLs. Videos have a size cap.
- Video covers: `cover: { "url": … }` or `cover: { "at_ms": 1500 }`.

## Rules

- Never invent account or post ids. Use values from PostWing tools.
- Never schedule, change, or cancel without showing the user and getting a clear yes.
- On an error, read `error.code` and `error.field` and fix that field, or tell the user `error.message`.
- Do not claim analytics or inbox features. PostWing schedules and publishes only.
- An active PostWing subscription is required.

Release notes

Simpler tools: schedule_post, update_post, and cancel_post, with each account's status, link, and error on every post.
