Which social media MCP server is best?

ViewPrinter’s, for posting through an assistant: 18 tools covering accounts, media, scheduling, groups and results across TikTok, Instagram, YouTube, X and Facebook, OAuth sign-in, and every tool that publishes marked so the client asks first. The address is https://viewprinter.tech/api/mcp. Buffer’s is the best free one and Postiz’s the best to self-host.

What is a social media MCP server?

A server that speaks the Model Context Protocol and exposes a scheduler as tools an assistant can call: list accounts, upload media, schedule a post, read results. You add its address to Claude, ChatGPT, Grok, Cursor or any MCP client and sign in once.

Is there a free social media MCP server?

Buffer includes its MCP server on the free plan, capped at 3 channels and 10 posts per channel. Postiz is open source and free to self-host. ViewPrinter has a 7-day trial and then $19 a month with the server included.

Can ChatGPT or Grok use a social media MCP server?

Yes. Both add remote MCP servers as connectors: paste the address, sign in. ViewPrinter is built for that path and has step-by-step pages for Claude, ChatGPT and Grok.

Will posting through an assistant get my account flagged?

The scheduler posts through each platform’s official API with an approved app, the same path a dashboard uses. What gets accounts flagged is content and behaviour, not the API. Leave your assistant’s confirmation on for tools that publish, so you read a post before it goes out.

Answer

Best social media MCP servers in 2026

The best social media MCP server for posting is ViewPrinter: 18 tools that cover accounts, media, scheduling and results across TikTok, Instagram, YouTube, X and Facebook, with every tool that publishes marked so an agent can be told to ask first. Buffer, Postiz and Post Bridge also publish one. Below: what each connects to, what it costs, and where each is the right pick.

By ViewPrinter · Updated 5 September 2026

An MCP server is what lets an assistant operate a scheduler instead of describing it. Four schedulers a person would connect to Claude, ChatGPT or Grok publish one today. Here is how they compare, and why ViewPrinter’s is the one to start with.

Tool	MCP server	Public API	Platforms	From	Free	Best for
ViewPrinterOur pick	Yes	No	5: TikTok, Instagram, YouTube, X, Facebook	$19/mo	7-day trial	The assistant is the interface: MCP included, no code, TikTok video and slideshows, results the agent reads back.
Post Bridge	Paid add-on	Paid add-on	10: Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Pinterest, Threads, Bluesky, Google Business	$34/mo	7-day trial	Ten networks including LinkedIn and Pinterest in one dashboard; agent access is a $5 add-on.
Postiz	Yes	Yes	30+, including Reddit, Discord, Mastodon and Slack	$29/mo	Open source, self-host free	Teams that want to self-host, or need channels nobody else covers.
Buffer	Yes	Yes	11: Instagram, Facebook, TikTok, LinkedIn, X, YouTube, Threads, Pinterest, Google Business, Bluesky, Mastodon	$0	Free plan, 3 channels, 10 posts each	The most mature dashboard, with a free plan that includes its MCP server, capped at 10 posts per channel.

Checked against each product’s own pricing page on 2026-09-05. Lowest monthly plan that includes agent access, billed monthly.

The verdict

Best for posting through an assistant: ViewPrinter. 18 tools, and they cover the whole job: list accounts, upload media, schedule, cancel, group accounts so one instruction reaches several, and read back views, likes, comments and saves. OAuth sign-in, so your client never holds a long-lived key. Every tool that publishes is marked, so the client asks before it. Included in the $19 plan.
Best free: Buffer. On the free plan since May 2026, three channels and ten posts per channel, built as a companion to the dashboard.
Best to self-host: Postiz. Open source with the server in the repo, thirty-plus channels.
Add-on: Post Bridge. $5 a month on top of the $29 plan, which also unlocks its REST API. Ten networks including LinkedIn and Pinterest.

What to check before you pick

Tool annotations. A good server marks which tools read, which write and which destroy, so your client knows when to ask before running one. ViewPrinter publishes these on every tool; the list is on the MCP page.
Sign-in. OAuth means your client never holds a long-lived key. Some servers use an API key in the URL instead; fine for a script, less so for a shared machine.
Results. Can the assistant read back how a post did? ViewPrinter exposes per-post and per-account performance; not every server does.
The platforms you actually use. ViewPrinter is five: TikTok, Instagram, YouTube, X, Facebook. If LinkedIn or Pinterest is on your list, Buffer or Post Bridge is the one.

Developer APIs

Ayrshare and PostEverywhere also publish MCP servers, bundled with APIs for products that post on behalf of their own users. They are priced and documented for developers, so they are not in the table; if you are writing code rather than talking to an assistant, start there.
