Is there an MCP server for Facebook, Instagram, TikTok and YouTube?

What each network publishes itself

Read on 11 October 2026, from each network’s own pages:

Meta’s developer page lists three official remote servers in all: Meta Ads MCP, Meta Social Technologies MCP, which manages the apps you build on developers.facebook.com (webhooks, app status, API health, documentation search), and WhatsApp Business Tools MCP. TikTok’s article says its server can load about 400 tools at once, or about 40 core tools with the rest found on demand.

What we did not read: TikTok’s separate tool-by-tool reference. The statement that its server posts nothing to a profile rests on the overview, which describes only advertising functions. Meta’s ads help page also warns that you may not have access to all of its tools yet.

What the ads servers do, and what Meta says to watch

These servers are useful if the job is a campaign, and Meta’s own pages are specific about the guard rails:

• Ads start paused. Meta’s help article says all ads the agent creates are paused until you set them live.
• Rules per ad account. Someone with full control of the business portfolio can allow or block actions such as creating campaigns or editing budgets for each ad account, in Meta Business Suite settings under Integrations, and the server enforces them.
• Scopes. The developer page says sign-in uses OAuth with Read and Manage scopes that you can change afterward in Business Integrations settings, and recommends keeping an app at Read unless the agent has to make changes.
• Prompt injection. The same page warns that anything an agent can call with the scopes you granted it can also be called in response to hidden instructions in content it reads, such as documents or web pages.

TikTok’s article says setup needs no developer credential, API key management or custom code.

How a post gets to a network instead

Posting goes through the network’s publishing API, and a posting MCP server is a layer on top of it:

• Facebook Pages. The Pages API publishes with a POST to the Page’s /feed edge, and schedules with published set to false and a scheduled_publish_time between 10 minutes and 30 days away. It also updates and deletes Page posts.
• Instagram. The Instagram Platform publishes single images, videos, Reels and carousels for professional accounts only, with a limit of 100 API-published posts in 24 hours.
• TikTok. The scopes reference lists video.publish to post content directly and video.upload to share it as a draft.
• YouTube. The Data API lets an app search YouTube content, upload videos and create and manage playlists.

Each of these needs an app that holds the network’s publishing permission for your account, which is why a person asking an assistant to post usually reaches the network through a service that already holds it. A server a third party wrote on top of the same API is not published on the network’s own pages, and we have not tested any of them.

Posting through Mellow Hub’s MCP server

Mellow Hub runs one remote MCP server at https://www.mellow.world/mcp for Instagram, TikTok, YouTube, X, LinkedIn, Threads, Bluesky, Pinterest, Facebook and Telegram. You connect each account through the network’s own sign-in (Bluesky takes a handle and an app password instead, and Telegram a bot you add to your channel), and the assistant connects to Hub with OAuth, so it never holds a network token or a password. Its main tools are whoami, list_channels, validate_post, create_post, get_post and post_results. Each network’s rules are checked before anything is sent, and the consent screen lets you choose accounts, whether posts wait for your approval, a daily limit and an expiry. The step-by-step pages per network are the Facebook, Instagram, TikTok and YouTube guides, and what an MCP server is explains the protocol.

The first 3 posts are free, however many networks each one goes to, and need no card. After that Hub is paid: plans start at $19 a month (Solo), after a 7-day trial with a card on file that costs nothing if you cancel before it ends, and a monthly plan's first month is 20% off. Publishing is unlimited on every plan, under a fair-use ceiling that stops automated floods (900 publications a month on Solo), where one publication is one post on one account, so a post sent to five networks counts as five toward it. There are no automatic overage charges.

Hub’s MCP tools do not run advertising campaigns or read other people’s accounts. Its keyword auto-reply tools for Instagram comments are open to every Hub profile since meta approved Mellow’s app for the Instagram messaging permission on 26 October 2026, and are not yet proven with an account that has no role on our Meta app. For ads, the networks’ own servers above are the tools.
