From the repository

Two connection methods are available. For hosted (OAuth) use: add the connector URL https://mcp.postfa.st/mcp in Claude or ChatGPT, then approve OAuth—no API key or self-hosting needed. For local use: run npx postfast-mcp with your PostFast API key in Cursor, VS Code, or Claude Code.

`list_posts`

List social media posts with optional filters for specific IDs, platform, status, and date range. Failed or missed posts carry a lastError { message, code }; codes include MISSED_DISCONNECTED (the account was disconnected when the post was due — reconnect, then retry) and MISSED_NOT_PUBLISHED (passed its scheduled time plus a 2h grace window without publishing).

`create_posts`

Create and schedule social media posts. Supports batch creation (up to 15 posts). Each post targets a specific social account. Scheduling to a disconnected account (connectionStatus DISABLED in list_accounts) is rejected with HTTP 400 "socialMediaDisconnected" — pre-check connectionStatus before calling. Saving as DRAFT to a disconnected account is allowed.

`delete_post`

Delete a social media post by ID

`get_post_analytics`

Fetch published posts with their latest performance metrics (impressions, reach, likes, comments, shares). Only returns published posts that have a platform post ID. LinkedIn personal accounts are excluded. Supported: Instagram, Facebook, TikTok, Threads, YouTube, LinkedIn (company pages), Pinterest (Business accounts). Pinterest extras include pin_clicks, outbound_clicks, saves_90d, save_rate_90d (saves are 90-day rolling because Pinterest API does not expose lifetime totals); video pins additionally surface mrc_views, views_10s, avg_watch_time, v50_watch_time, video_starts, quartile_95_views. Video posts also include normalized watch-time on latestMetric: avgWatchTimeSeconds, totalWatchTimeSeconds, videoViews (Facebook, Instagram Reels, YouTube, Pinterest, LinkedIn company pages).

`list_accounts`

List all social media accounts connected to the workspace. Each account includes connectionStatus (CONNECTED or DISABLED) and disabledReason (null unless DISABLED). If connectionStatus is DISABLED, the account will not publish until the user reconnects it.

`list_pinterest_boards`

List Pinterest boards for a connected Pinterest account

`list_youtube_playlists`

List YouTube playlists for a connected YouTube account

`list_gbp_locations`

List Google Business Profile locations for a connected GBP account

`get_follower_history`

Daily follower-count snapshots for a connected account, plus the current count (currentFollowerCount) and the net change (delta) over the range. Date range via from/to (ISO 8601); defaults to the last 90 days, capped at 365. Tracking is forward-only: data starts at trackingStartedAt (when PostFast began recording this account), with no snapshots before then. All counts are strings (bigint); currentFollowerCount, delta, and trackingStartedAt may be absent until the account has its first snapshot. Coverage: Facebook Pages, Instagram, YouTube, Pinterest, Threads, Bluesky, Telegram, LinkedIn company pages. Not available: X, TikTok, personal Facebook.

`search_places`

Find a place to tag. The returned id works for both facebookPlaceId and instagramLocationId.

`generate_connect_link`

Generate a shareable link for external clients to connect their social accounts to the workspace

`get_upload_urls`

Get signed upload URLs for media files. Upload your file to the returned URL via PUT, then use the key in create_posts mediaItems.

`upload_media`

Upload a local file to PostFast and get back a media key for use in create_posts. Handles the full flow: detects content type, gets a signed URL, uploads the file, and returns the key and type.

PostFast MCP

PostFast is a hosted MCP server for scheduling and publishing social media posts directly from AI assistants like Claude, ChatGPT, and Cursor.

Two ways to connect

- Hosted (OAuth): add the connector URL https://mcp.postfa.st/mcp in Claude or ChatGPT, approve OAuth, done. No API key, nothing to self-host. - Local (npx): run npx postfast-mcp with your PostFast API key in Cursor, VS Code, or Claude Code.
