What data it sees

Do you need an account

No: the server works without sign-in

Schedule and publish social media posts to 11 platforms (X, Instagram, Facebook, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky, Telegram, Google Business Profile, and more), straight from Claude, ChatGPT, or Cursor

Hosted MCP server with OAuth, so there is no API key and nothing to self-host. Draft, schedule, approve, publish, and pull post analytics in natural language. 15 tools

How to connect

How to connect PostFast to Claude

The server address to paste into Claude settings:

https://postfast--me-bz42.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect PostFast to ChatGPT

The server address to paste into ChatGPT settings:

https://postfast--me-bz42.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

https://postfast--me-bz42.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (15)

Raw names from tools/list. Only developers need these.

list_workspacesList the workspaces this connection can act in. Use a workspace id as the optional workspaceId argument on other tools to operate across multiple workspaces (the default workspace is used when omitted).
list_accountsList all social media accounts connected to the workspace. Each includes connectionStatus (CONNECTED or DISABLED) and disabledReason (null unless DISABLED), plus followerCount (latest stored snapshot, a string; absent for platforms without follower data) and followerCountUpdatedAt. A DISABLED account will not publish until the user reconnects it — pre-check before scheduling. For a follower trend over time, use get_follower_history.
get_follower_historyDaily follower-count snapshots for one connected account (pass its socialMediaId from list_accounts). Returns currentFollowerCount, delta (current − first snapshot in range), trackingStartedAt (when tracking began), and a series of { capturedAt, followerCount } points. Counts are strings. Optional from/to bound the range (ISO 8601; default last 90 days, capped at 365). Snapshots are forward-only — no data before trackingStartedAt. Coverage: Facebook Pages, Instagram, YouTube, Pinterest, Threads, Bluesky, Telegram, LinkedIn (company pages). Not available: X, TikTok, personal Facebook.
list_pinterest_boardsList Pinterest boards for a connected Pinterest account (pass its socialMediaId). Use a returned board’s boardId field as controls.pinterestBoardId in create_posts.
list_youtube_playlistsList YouTube playlists for a connected YouTube account (pass its socialMediaId). Use a returned playlist’s playlistId field as controls.youtubePlaylistId in create_posts.
list_gbp_locationsList Google Business Profile locations for a connected GBP account (pass its socialMediaId). Use a returned location’s locationId field as controls.gbpLocationId in create_posts.
search_placesSearch for a place to geotag a post. Pass free text (min 2 chars, e.g. a venue name or address); returns matching places, each with an id that works as BOTH controls.facebookPlaceId (Facebook feed posts) and controls.instagramLocationId (Instagram single-media posts). Only Facebook Pages that carry location data are returned.
generate_connect_linkGenerate a shareable link for external clients to connect their social accounts to the workspace.
list_postsList social media posts with optional filters for platform, status, date range, and specific post ids. Failed/missed posts carry lastError { message, code }; codes include MISSED_DISCONNECTED (the account was disconnected when due — reconnect, then retry) and MISSED_NOT_PUBLISHED (passed its scheduled time plus a 2h grace window).
create_postsCreate and schedule social media posts (batch up to 15). Each post targets one social account (socialMediaId from list_accounts). SCHEDULED requires scheduledAt on every post; DRAFT must omit scheduledAt. Scheduling to a DISABLED account is rejected — pre-check connectionStatus (saving as DRAFT is allowed). TikTok, Instagram, YouTube, Pinterest, and Google Business Profile require at least one media item EVEN FOR DRAFTS — attach media first (ask the user for an image/video, or generate+upload one, if none was provided). Attach media via the key returned by upload_from_url / upload_media.
approve_postsSet the approval status of one or more posts (approval workflow). Typically used to move posts to APPROVED so they can publish, or to PENDING_APPROVAL / REJECTED / NEEDS_WORK.
delete_postDelete a social media post by id.
get_post_analyticsFetch published posts with their latest metrics (impressions, reach, likes, comments, shares). Only published posts with a platform post id are returned; LinkedIn personal accounts are excluded. Supported: Instagram, Facebook, TikTok, Threads, YouTube, LinkedIn (company pages), Pinterest (Business). Metric counts are returned as strings; Pinterest/video pins include extra fields in metric.extras. Video posts also include normalized watch-time on latestMetric: avgWatchTimeSeconds, totalWatchTimeSeconds, videoViews (Facebook, Instagram Reels, YouTube, Pinterest, LinkedIn company pages).
upload_from_urlFetch media from a public https URL and store it for use in create_posts. Returns { media_id, type }; pass media_id as a mediaItems[].key. Ideal for ChatGPT/Claude-generated image URLs and remote CDN media. Redirects are followed (each hop is SSRF-validated); the URL must be public https and within the size limit. Supported types: image/jpeg, image/png, image/gif, image/webp, video/mp4, video/webm, video/quicktime.
upload_mediaUpload an image/video that is present in this conversation, for use in create_posts. Pass EITHER a ChatGPT-attached or model-generated file (the `file` argument — ChatGPT fills this automatically) OR base64 bytes (`data` + `contentType`). Returns { media_id, type }; use media_id as a mediaItems[].key. For large or remote media, prefer upload_from_url. Supported types: image/jpeg, image/png, image/gif, image/webp, video/mp4, video/webm, video/quicktime.
