Checked against each vendor's own docs and pricing page on November 7, 2026.
The best social media MCP server depends on what your agent should do. For a free start, look at Buffer or Metricool. For the longest channel list, Postiz. For a product you are building, Zernio or Ayrshare. If you want the agent to write in your brand's voice and show you each draft before scheduling, that is what we built Skryvo for.
The short version: all six let an agent such as Claude schedule social posts. They differ on price, sign-in and who approves a post. Buffer's own guide warns that its create tool "can publish immediately" and tells you to leave your AI client's approval prompts on. Everything below was read from each vendor's docs and pricing page on November 7, 2026. We did not run a test of each server.

What is a social media MCP server?
It is a connection that lets an AI agent use a social media tool. MCP, the Model Context Protocol, gives Claude, ChatGPT, Cursor and similar agents a list of actions they can take, such as listing your channels or scheduling a post. The server does the posting through the vendor's accounts and permissions, so the agent does not need your social media password.
In Claude these connections are called connectors. A vendor's own hosted server is a different thing from a script that drives your logged-in browser, which our guide to LinkedIn MCP servers explains. This page covers only vendors' own hosted servers.
Best for a free start: Buffer
Buffer's server covers channels, posts, ideas, templates and post metrics across its 12 channels, including Bluesky, Mastodon, Threads and Substack. Its docs name no plan requirement for the server, and every plan includes API access. Free connects up to 3 channels with 10 scheduled posts each. Essentials is $5 a channel a month billed yearly ($60 a year), with a 14-day trial.
The trade-off is cost as you add channels, since the price is per channel, and it has no WordPress or Dev.to publishing in its channel list. See our Buffer alternatives if the per-channel price adds up.
Best with analytics: Metricool
Metricool's server reads brands, analytics and scheduled posts, and can schedule and edit posts. Its help centre says the server "works with any Metricool plan, including Free", and plan limits still apply. Free covers 1 brand and 20 scheduled posts a month but leaves out LinkedIn and X. Starter adds LinkedIn, and X is an add-on. Starter is $25 a month, or $20 billed yearly, for up to 5 brands.
The inbox, Smartlinks, autolists and ads campaign management are not available through the server. Pick it if you want your agent to answer questions about performance as well as schedule.
Best for the most channels: Postiz
Postiz says 30+ channels, including Reddit, Dev.to, Medium, Nostr and Lemmy, and its docs describe 13 tools, among them image and video generation. Every hosted plan includes the server: Standard is $29 a month for 5 channels ($23 billed yearly) and Ultimate is $99 for 100, each after a 7-day trial. You can also host the open-source code yourself.
Its MCP page describes no built-in approval step. It suggests reviewing the queue in Postiz before posts go out, and its scheduling tool can draft or publish immediately, so say which one you want in your request. Skryvo vs Postiz compares the two in more detail.
Best for pricing by account: Zernio
Zernio calls itself marketing infrastructure for agents, with a hosted server, SDKs and 16 platforms. Its docs describe 20 core tools, with others loaded on demand. It has no plans or seats: the first 2 accounts are free, accounts 3 to 10 cost $6 a month each, and the price falls after that.
Passing is_draft: true saves a draft instead of publishing, and the docs recommend one API key per agent so each can be revoked. Its pricing says every feature is included, with no plans or seats. It suits developers more than a marketer who wants a calendar to look at.
Best for products that post for clients: Ayrshare
Ayrshare's server has 33 tools for posting, history and analytics, comments and direct messages, and creating profiles, across 14 networks. Premium is $149 a month and Launch is $299, with a 28-day trial on Launch only. Working with client profiles and sub-profiles requires a Business plan at $599 a month, or Enterprise.
It signs in only with an API key in a request header, so its docs say Claude Desktop and personal claude.ai connectors cannot use it and recommend Claude Code; Cursor, VS Code and n8n work too. Its Claude Code plugin adds a confirmation hook. Posting to X also needs your own X API credentials. That fits a developer building a product, not someone who wants to connect from a chat window.
Best for brand-voice writing with a go-ahead: Skryvo
We make Skryvo, so weigh this one accordingly. Beyond scheduling, its tools write posts, articles, emails and ads in your saved brand voice, design a picture in your brand's look, plan a calendar and report results. On ChatGPT the tools are social posts and pictures for now. They tell the agent to show you each draft and get your go-ahead before scheduling, and you can cancel any scheduled post before it goes out. An instruction to an agent is not a lock, so read what it shows you. After publishing, Skryvo reads each post back where the platform allows it.
The trade-offs are real. There is no free plan, only a 7-day trial on Hobby or Pro with a card at checkout. Instagram, Facebook Pages, LinkedIn Pages and Threads are built but still waiting for platform approval, so choose another server today if your audience is there. It has no Reddit, and it is a young product without many reviews yet. Hobby is $15 a month with 30 X posts; the Claude setup is a sign-in with no API key to copy.
Does an MCP server post without asking you?
It can. Most of these servers can publish as soon as the agent calls the tool, and the check usually sits in your AI client, which shows the tool call and asks you to approve it. Buffer's guide says most clients ask first. Turning those prompts off for convenience removes the only check some setups have.
Three habits help whichever server you pick. Ask for drafts or a schedule instead of an immediate post. Keep approval prompts on for anything that creates or deletes. Start with one channel you can watch. Buffer's docs also note that its delete tool cannot be undone, so read what a tool does before you allow it.
How to choose a social media MCP server
- List your channels first. If Instagram or Reddit matters, that removes some options right away.
- Check your AI client. A key-only server will not work in a client that can only sign in with OAuth.
- Decide who writes. If your agent writes well enough for you, a scheduler is enough. If each post has to sound like your brand, compare the voice tools.
- Price your real channel count. Per-channel and per-account prices look small until you add ten.
- Run one real week. Schedule from your agent, then check what went out on the platform itself.
What this comparison does not tell you
We read documentation; we did not measure reliability, post failures or support on these servers, so none of them is ranked by how well it posts. Docs change, and a page that does not mention an approval step does not prove there is none. Channel counts are each vendor's own, and some list channels another would count differently. Check the current page before you pay. For one job in detail, see an MCP server for LinkedIn, X and Bluesky or our comparison of social media management tools if you do not need an agent at all.
