Preflight MCP server

Also listed on Smithery and the official MCP registry.

Preflight is a social media scheduler that checks every post against each network's real publishing rules before it leaves.

The server itself is hosted at https://preflight.social/mcp; its source is not in this repository.

What the tools do

The tools fall into five jobs.

• Draft: draft_post puts a text draft in the composer. It cannot publish.
• Check: validate_post is a dry run of create_post with the same arguments. It checks every channel, file, time and network limit and creates nothing.
• Schedule or publish: create_post, with files through create_media_upload, complete_media_upload and get_media. The bytes never pass through the assistant.
• Manage: list_posts, get_post, update_post, delete_post, retry_post, edit_published_post, delete_published_post.
• Learn: post_performance, post_insights, analytics_summary, audience, list_comments, act_on_comment.

Also: list_channels, next_queue_times, list_pinterest_boards, create_pinterest_board, list_youtube_playlists, create_youtube_playlist, tiktok_creator_info, get_usage.

Everything an assistant publishes goes through the same checks as the web composer and the REST API, so a post that a network would refuse is stopped before it is sent.

Scopes

Scope	Lets the assistant
posts:read	read channels, posts, comments, figures and usage; run validate_post
posts:write	write drafts, edit or delete posts that have not gone out
posts:publish	anything that goes live
media:read, media:write	see and upload files

Publishing is its own scope. A connection without posts:publish can still draft.
