A side-by-side look at the 1Social and Postfast MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose 1Social for social media work as a local process; choose Postfast MCP for social media as a local process. You can also run both side by side in one mcpServers block.

list_accountsConnected accounts, what each network accepts, current plan, remaining quota. Call it first — channel ids come from here.preview_postFree dry run: per-network limits, media requirements, threading behaviour, quota cost. Nothing is published.publish_postPublishes now, or schedules up to 30 days ahead. Returns a per-network receipt. Takes an `idempotencyKey`.list_postsPosts with their delivery outcome per network — delivered, failed with a reason, cancelled, or `unknown` — plus stored engagement metrics.update_postEdits a post that has not been sent yet. The networks have no edit endpoint, so it withdraws and replaces.cancel_postUnschedules a post and releases the quota it reserved.delete_postDeletes from 1Social and attempts removal from each network. See [What deletion can and cannot do](#what-deletion-can-and-cannot-do).retry_deliveryRetries one failed network, leaving the successful ones alone. Refused for permanent failures.upload_mediaPre-signed upload target, for clients that cannot attach a file to a tool call.confirm_deliveryRecords **your** answer about a delivery whose outcome was unknown: is the post live on that network or not?list_accountsList connected social media accounts (each with `connectionStatus` — `CONNECTED`/`DISABLED` — `disabledReason`, `followerCount`/`followerCountUpdatedAt`, and `inboxCapable`)list_postsList posts with filters (specific IDs, accounts, platform, status, date range); each post carries its key settings in `controls` (Threads topic, Instagram/Facebook format, TikTok draft flag, YouTube privacy)create_postsCreate and schedule posts (batch, up to 15)delete_postDelete a post from PostFast by ID (does not remove an already-published post from the platform)delete_postsDelete up to 100 posts from PostFast in one call; returns `deletedIds` and `notFoundIds` (does not remove already-published posts from the platform)upload_mediaUpload a local file and get a media key (handles the full flow)get_upload_urlsGet signed URLs to upload media fileslist_pinterest_boardsGet Pinterest boards for an accountlist_youtube_playlistsGet YouTube playlists for an accountlist_gbp_locationsGet Google Business Profile locations for an accountsearch_placesFind a place to tag posts (the `id` works for both `facebookPlaceId` and `instagramLocationId`)generate_connect_linkGenerate a link for clients to connect accounts — optionally scoped to specific platforms, with a `redirectUrl` the user returns to (carrying `status`, `platform`, `accountId` and your own `externalId`, plus `accountIds` after a Facebook or LinkedIn page step)Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
