MCP Servers with a cancel_post tool

Every MCP server Pod knows of that exposes a cancel_post tool.

9 servers, ordered by decision readiness and adoption — GitHub stars and npm downloads where available, then reported issue volume. Pod has connected to 3 of them; the rest are publisher-reported and unverified.

1Social

1Social publishes to Instagram, TikTok, LinkedIn, X (Twitter), Facebook, Threads and Bluesky from a single message — right away, or scheduled up to 30 days ahead.

Before anything goes out, Claude can check the draft: per-network character counts, whether a network requires an image (Instagram and TikTok refuse posts without one), whether a multi-part post will publish as a native thread or be joined into a single post, and what it would cost against your remaining quota. The check publishes nothing and spends no quota.

After publishing, Claude reports each network separately — what landed, with a link to the live post; what failed, with a readable reason; and the rare case where 1Social genuinely cannot tell. A network that failed can be retried on its own, without re-posting to the ones that already went out. Anything still scheduled can be edited or unscheduled, and deleted from the networks whose APIs allow deletion.

Attach an image or video straight from the conversation, or pass a public URL.

Ten tools: list_accounts, preview_post, publish_post, list_posts, update_post, cancel_post, delete_post, retry_delivery, upload_media, confirm_delivery.

Connecting your social accounts happens in your browser at 1social.dev, through each network's own OAuth flow. There are no API keys to paste, and the agent never sees the credentials for your social accounts.

Every account gets 30 deliveries a month free — pricing is per delivery, so one post to seven networks is seven deliveries. Paid plans are Solo $19/mo and Pro $39/mo.

DunSocial

DunSocial connects Claude to your social publishing workspace so you can create drafts, schedule posts, and publish approved content across X (Twitter), LinkedIn profiles and Business Pages, Instagram, Threads, Bluesky, Reddit, Pinterest, and YouTube Shorts. TikTok publishing is available in limited beta.

Plan platform-specific content, schedule X threads, prepare Instagram images, carousels and Reels, publish Reddit posts and Pinterest Pins, and manage video content for supported destinations. Supported formats, media requirements, and account permissions vary by platform.

Review scheduled and published posts, reschedule or cancel queued content, manage reusable drafts and media assets, and access connected accounts and workspace details. Save and search brand memories, organize collections, and manage your workspace voice profile to help keep content consistent.

Connect securely with OAuth and choose the DunSocial workspace Claude can access. Users choose the content, destination accounts, and publishing time. Drafts stay unpublished until you choose to schedule or publish them. DunSocial does not provide social inbox, comment, or direct-message management.

KreatoAI

KreatoAI relie Claude à vos réseaux sociaux : Facebook, Instagram, TikTok, LinkedIn et YouTube. Demandez à Claude de publier un texte, une image ou une vidéo tout de suite ou à l'heure de votre choix, de décaler ou d'annuler une publication programmée, ou de vous dire si un envoi est parti et où le voir. Claude passe par votre compte KreatoAI et les réseaux que vous y avez connectés, et vous demande votre accord avant chaque publication.

Il vous faut un compte KreatoAI (kreatoai.com) avec au moins un réseau connecté. Publier et programmer font partie de l'abonnement, avec 7 jours d'essai.

KreatoAI connects Claude to your social media accounts: Facebook Pages, Instagram, TikTok, LinkedIn and YouTube. Ask Claude to publish or schedule a text, image or video post, reschedule or cancel a scheduled post, or check whether a post went out and get its link. Claude acts through your KreatoAI account and the networks you connected there, and asks for your approval before publishing. Requires a KreatoAI account with at least one connected network; publishing and scheduling are part of the subscription (7-day trial).

Kadenzo

Kadenzo is a social media scheduler. Connect your Kadenzo account and Claude can plan and schedule posts to the accounts you've linked in Kadenzo: Instagram, Facebook, TikTok, LinkedIn, X, Threads, Bluesky, Pinterest, YouTube, Mastodon and Telegram.

Ask Claude to draft a post and schedule it for Tuesday at 9am on two accounts, with shorter text for X and a thread for Bluesky. Check whether a post fits each network's limits before it goes out. Move, edit or cancel anything in your queue. See how your recent posts performed, find your best times to post from your own engagement history, and catch up on who is mentioning your brand or your competitors.

Kadenzo always schedules for a future time and never publishes instantly, and Claude asks before anything is scheduled, changed or cancelled. You need a Kadenzo account on the Professional plan or higher. You can disconnect Claude any time under Settings → API keys in Kadenzo.

Postbase

Postbase is a social media scheduler with a calendar for X, LinkedIn, Bluesky, Mastodon, TikTok and YouTube. This connector lets Claude work with your Postbase workspace in plain language.

What Claude can do: • List your connected social accounts • Write and schedule posts and threads, or save them as drafts • Show what's scheduled, drafted, published or failed • Cancel a scheduled post (it goes back to being a draft, so nothing is lost)

Everything Claude creates lands on your Postbase calendar, where you can review, edit or cancel it before it goes out. Posts publish through each network's official API at the time you choose. Threads post as reply chains on X, Bluesky and Mastodon; on LinkedIn, extra parts become the first comment.

Claude can't delete posts, disconnect accounts or change settings. You sign in with Postbase (no API key), pick which workspace Claude can access, and can revoke access at any time from Developers → Connected apps.

Posts are text and threads today; add images and video in the Postbase composer.

PostDaily

PostDaily is a social media scheduler for businesses, marketing teams and creators. Connect it and ask in plain words to draft, schedule and publish posts to Instagram, Facebook, TikTok, YouTube, X, Threads, Pinterest, Bluesky and Mastodon, see what is in your queue, retry posts that failed and review how published posts performed.

Before saving a post, PostDaily checks it against each network's main limits, such as length, media and thread rules, creates one post per channel and shows a preview of each in the conversation. When you connect, you choose what Claude may do (full access, drafts only or read only) and which workspaces it can use. Publishing a post immediately asks for your confirmation first.

You need a PostDaily account with at least one connected social channel. Disconnect any time in PostDaily under Settings → AI agents.

SkedCast

SkedCast is a social media scheduler for agencies, creators and teams. This MCP server lets Claude work inside your SkedCast workspace: draft a post, check it against each platform's rules, schedule it, and report back on how it performed.

What Claude can do

• Read: posts and their destinations, connected accounts, clients, campaigns, approvals, media library, reports, posting limits, and analytics (overview, per post, per account, per client) plus best-time-to-post recommendations.
• Act: create and schedule posts (one or many), validate a post before creating it, revise drafts and scheduled posts, reschedule, cancel or retry a destination, manage campaigns and clients, import media from a URL, and decide approvals.
• Set up: register webhooks and generate account-connect links.

Built to be safe

• You approve the connection with OAuth 2.1 and can revoke it any time.
• Claude acts as you, never more: your role and per-client permissions still apply.
• Tools that change something are clearly marked and ask first.
• Approval workflows, platform rules, posting limits and rate limits still apply.

Works with 11 social platforms. AI assistant access is included on paid plans; a free trial is available at skedcast.com.

Sydium

Sydium is a social media operating system for creators, small businesses and agencies. This connector puts your Sydium workspace inside Claude, so the work of drafting, scheduling and checking on posts happens in the conversation you are already in.

What you can do from a chat:

• See which social accounts are connected and what each platform accepts (post types, media limits, caption lengths).
• Draft captions in your own brand voice, learned from what you have already published.
• Add an image or video by link and learn up front which platforms will take it.
• Publish now or schedule to Instagram, TikTok, YouTube, Facebook, LinkedIn, X, Pinterest, Threads, Bluesky, Mastodon and Google Business Profile, with per-platform options such as Pinterest boards, TikTok privacy settings and Google Business calls to action.
• Draft a carousel from slide text you write. Sydium renders it in your brand style and gives you a link to review the slides and schedule.
• Review the upcoming queue, read a post's full caption, change its text, media or time, or cancel it.
• Pull today's content idea from Muse and read account analytics over any date range.
• Agencies act for a specific client workspace with the same permissions they have in the Sydium app.

Publishing is explicit. The publish tool is annotated as destructive, so Claude confirms before anything lands on a public feed, and a scheduled post stays editable or cancellable until it goes out. Media is stored in Sydium first, so publishing never fetches from arbitrary URLs.

Requires a Sydium workspace with an active plan or trial. Connecting authorizes exactly one workspace through OAuth; it does not create an account or start a plan, and plans are managed at sydium.com. Social accounts are connected in the Sydium app, not through this connector.

UniPost

UniPost connects Claude to the social accounts you manage: Instagram, Facebook Pages, TikTok, and YouTube. Ask Claude to schedule posts with images or video, review what's queued, cancel what you don't need, and see views, likes, comments, and shares for what you've published.

Nothing is published until you approve it. Claude shows you the post, and you approve it by saying so in the chat, through a one-click approval link, or in the UniPost dashboard. TikTok posts are always approved in UniPost, where you choose TikTok's privacy and interaction settings.

Sign in with your UniPost account the first time you connect and choose which workspace Claude can use. Only workspace owners and admins can connect, and each connection reaches only the workspace you chose. Your first connected social account is free.
