Best social media MCP servers (2026): 12 compared from their own pages
12 MCP servers for posting to social media from Claude, ChatGPT or Cursor: OAuth or API key, networks, review, price and free plans.
By Mellow · UpdatedThe short answer
A social media MCP server lets an AI assistant such as Claude, ChatGPT or Cursor publish and schedule posts for you. The 12 below differ in four ways: whether they sign in with OAuth (which claude.ai and ChatGPT connectors need) or only with an API key; how many networks they post to, from five to thirty; whether an agent's post waits for a person; and whether the MCP server comes with a free plan.
Disclosure: Mellow publishes this page and makes Mellow Hub, one of the servers below. Hub’s row comes from its own code and pricing configuration. Every other cell links to the vendor’s own page, read signed out on 10 November 2026; where a vendor’s pages disagree, the cell says so. Rows are in alphabetical order, not ranked.

| Ayrshare | Remote server at https://api.ayrshare.com/mcp, over Streamable HTTP and stateless. Sources: Ayrshare: MCP server docs, Ayrshare: Connect to the MCP server | API key only: every tool call needs "Authorization: Bearer YOUR_API_KEY", with an optional Profile-Key header. There is no OAuth ("Ayrshare does not publish OAuth metadata"), so personal Claude.ai, Desktop and mobile connectors can't authenticate. Source: Ayrshare: Connect to the MCP server | The API docs list 14 networks: Bluesky, Facebook, Google Business Profile, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, Telegram, Threads, TikTok, WhatsApp, X and YouTube. The MCP pages don't list networks separately. Since March 31, 2026, X needs your own OAuth 1.0a key pair, sent as extra headers. Sources: Ayrshare: API overview, Ayrshare: Connect to the MCP server | Yes. create_post ("Publish to one or more linked platforms") comes with validate_post (a dry run), update_post ("Update a scheduled or awaiting-approval post") and retry_post. The AI-agent page says "Approve-before-publish by default", and the Claude Code plugin includes a confirmation hook. Sources: Ayrshare: MCP tool catalog, Ayrshare: AI agent page, Ayrshare: Connect to the MCP server | Premium: $149/mo billed monthly, for 1 profile with up to 14 accounts. The pricing page doesn't say which plans include MCP. Working with profiles and sub-profiles needs a Business plan: $599/mo monthly, or a $499/mo base billed annually, with 30 profiles included. Sources: Ayrshare: pricing, Ayrshare: MCP server docs | No free plan is listed. Launch ($299/mo) has a 28-day free trial, with no word on a card.

Source: Blotato: MCP setup (help) | Nine: X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky and Pinterest. Source: Blotato: AI agent page | Yes. blotato_create_post publishes and accepts a scheduled time on all nine platforms, and schedule tools list, get, update and delete the queue. No draft or approval mode for posts is documented. Sources: Blotato: AI agent page, Blotato: MCP setup (help) | Starter: $29/mo, with 20 social accounts, 1,250 AI credits a month, and API and MCP included. Yearly billing "saves about 17%" (pay for 10 months, get 12), but no yearly price is shown. Source: Blotato: pricing | No free plan. A 7-day trial needs a card, and nothing is charged during it. The trial excludes API and MCP: "Generating a key during a trial ends the trial and starts billing." Sources: Blotato: pricing, Blotato: MCP setup (help) |
| Buffer | Remote server at https://mcp.buffer.com/mcp, which the developer docs call "the only Buffer MCP endpoint". Source: Buffer: MCP developer guide | Both. The developer guide says "Most AI tools connect over OAuth, with no API key". A client that lets you set a request header can send a personal API key as "Authorization: Bearer YOUR_API_KEY". Sources: Buffer: MCP developer guide, Buffer: Other AI tools guide, Buffer: MCP page | The developer guide says create_post works for Instagram, Facebook, Twitter, LinkedIn, Pinterest, YouTube, Google Business, Mastodon, TikTok, Threads, Bluesky, Substack and Start Page.

Source: Buffer: MCP developer guide | Yes. create_post "Schedules or publishes a post on one channel" in four modes: addToQueue (the default), shareNow, shareNext and customScheduled. The docs warn it "can publish immediately". Buffer documents no approval mode of its own for MCP; the docs say only that "Most MCP clients ask you to approve" write actions. Source: Buffer: MCP developer guide | Essentials shows "$5 /month" per channel with "$60 billed yearly (save 2 months)"; the page's default view doesn't show a separate month-to-month price. Team shows $10/month per channel, $120 billed yearly. buffer.com/mcp says "MCP access is included on every plan, including Free." Sources: Buffer: pricing, Buffer: MCP page | Free plan: up to 3 channels and 10 scheduled posts per channel at a time, with MCP included. Paid plans have a 14-day free trial.

Source: Hootsuite: Perch page | Yes, through Perch: it drafts, schedules and cross-posts, and the Claude guide says you can "draft, plan, or publish a post". Claude "follows the same permissions and approval workflows your team already uses"; the plans table puts post approval workflows on Advanced and Enterprise. Sources: Hootsuite: MCP integrations page, Hootsuite: post from Claude (blog), Hootsuite: plans | The FAQ says "Paid plans start at $99 USD per user/month" for Standard, which has 10 social accounts; the plan cards are "based on annual billing", and no monthly figure is given. The plans table puts only the "Lumen MCP connector" on a plan (Enterprise) and doesn't assign Perch MCP to any plan. Sources: Hootsuite: plans, Hootsuite: MCP integrations page | No free plan.

Most clients use URL-based OAuth (paste the URL, sign in, grant access). n8n sends the Metricool API key in an "X-Mc-Auth" header. The marketing page also mentions a user token plus user ID. Sources: Metricool: How to connect the MCP (help), Metricool: MCP for Claude page | Instagram, TikTok, LinkedIn, Facebook, X (Twitter), YouTube, Pinterest, Threads, Bluesky and Twitch, plus Meta Ads, Google Ads and TikTok Ads (analytics only for the ad platforms).

| Postiz | Hosted. The docs give https://mcp.postiz.com/mcp (Bearer) and https://mcp.postiz.com/mcp/your-api-key (key in the URL). postiz.com/mcp gives https://mcp.postiz.com/mcp-oauth-dynamic for OAuth. Self-hosted: https://your-postiz-server.com/mcp/your-api-key. Sources: Postiz: MCP docs introduction, Postiz: MCP client setup, Postiz: MCP page | Both, but the pages disagree on which comes first.

Old URLs with the key in the query string still work but are discouraged. Sources: Typefully: MCP server (help), Typefully: AI agents page, Typefully: MCP server card | The MCP pages list X, LinkedIn, Threads, Bluesky and Mastodon.

Which one fits which need
- A free start. Buffer (3 channels), Metricool (20 posts a month), Upload-Post (10 uploads a month, no TikTok), Typefully (10 posts a month) and Zernio (2 accounts) include MCP on a free plan.
- claude.ai or ChatGPT as the client. Pick a server with OAuth: every one here but Ayrshare, which documents an API key only.
- The most networks. Postiz names thirty on its MCP page, Zernio sixteen to eighteen, Ayrshare fourteen in its API docs. Typefully’s MCP pages name five text networks.
- A person approves what the agent posts. Mellow Hub’s review mode, Ayrshare’s approve-before-publish, Metricool’s posts sent for review, Hootsuite’s post approval workflows on Advanced and Enterprise.
- A team already on one suite. Hootsuite splits MCP into four servers (content, inbox, listening, advocacy); Metricool adds analytics and ad accounts.
- Agents that build products. Ayrshare and Zernio price for developers: Ayrshare per profile from Premium, Zernio per connected account.
Zapier MCP is not in the table: it runs actions of the apps you connect in Zapier rather than knowing each network’s rules. MCP is included in every plan. Pro starts at $19.99/mo billed annually or $29.99 billed monthly, for 750 tasks a month (USD).

What to check before an agent posts for you
The table answers what each server can do. Whether it is safe to hand an agent depends on a few more things: whether a key can be limited to some channels, whether there is a daily ceiling, whether every action is logged, and whether revoking applies at once. They are listed, ten of them, in Before an AI agent posts: an MCP checklist. How Mellow Hub does each one is in Publish to social media with an MCP server.
Where Mellow Hub fits, and where it does not
Mellow Hub publishes one post to 10 networks at once, by hand in its composer or through an AI agent, and checks every network’s rules before anything is sent. It is built for agents that publish: each key or OAuth grant is limited to the channels, the mode, the daily ceiling and the expiry its owner chose, and every action is recorded where the owner can revoke it. It is weaker in these ways:
- No free plan. Publishing needs a plan. A new account starts with a 7-day free trial of a monthly plan, which takes a card; a yearly plan is charged the day it is chosen.
- 10 networks. No Google Business Profile, Mastodon, Reddit or Snapchat.
- No inbox and no listening. No shared inbox, comment moderation or monitoring. On Instagram it answers by keyword: a comment gets a public reply and one private message, a direct message gets an answer (comment-to-DM). Analytics are per post.
- No team seats. One owner’s brand profiles, without roles or client logins.
- Newer. Mellow has published live, with public links, to Instagram, YouTube, X, LinkedIn, Threads, Bluesky, Pinterest and Facebook. On TikTok, uploads are accepted but, on our test accounts, visible only to their owner.
See the plans, each network’s rules, or the comparison of publishing APIs if an agent or your own code will do the posting.
Questions
What is the best MCP server for posting to social media?
This page does not rank them, because they suit different jobs. For a free start with an AI agent: Buffer, Metricool, Upload-Post, Typefully and Zernio include MCP on a free plan or free accounts, each with its own limit. For the most networks: Postiz names thirty on its MCP page, Zernio sixteen to eighteen (its pages disagree). For an agent that must not post without a person: Mellow Hub has a review mode, and Ayrshare says approve-before-publish by default. The table says what each one costs and covers.
Which social media MCP servers work in claude.ai and ChatGPT?
Those that sign in with OAuth, because a claude.ai or ChatGPT connector cannot send an API key: Buffer, Postiz, Zernio, Blotato, Metricool, Upload-Post, Post Bridge, Publer, Hootsuite, Typefully and Mellow Hub document OAuth. Ayrshare documents an API key only, so its own page says personal Claude.ai, Desktop and mobile connectors cannot authenticate.
Is there a free social media MCP server?
On 10 November 2026: Buffer's free plan includes MCP for 3 channels; Metricool's free plan has 20 scheduled posts a month; Upload-Post's free plan has 10 uploads a month without TikTok; Typefully's free plan has 10 posts a month; Zernio's first two connected accounts are free. Postiz, Blotato, Publer, Hootsuite, Ayrshare and Mellow Hub have no free plan with MCP, and Post Bridge’s pages describe none; several of them have trials.
Can an AI agent post to social media without me approving each post?
With most of these servers, yes: the agent's tool publishes or schedules directly, and your MCP client may ask you to confirm. Some document a review step of their own: Mellow Hub's review mode holds an agent's posts for a person, Ayrshare describes approve-before-publish by default, Metricool can send posts for review, and Typefully's drafts can carry comments. Read each server's own page before giving an agent autopilot.
Do I need an MCP server, or is Zapier enough?
Zapier MCP runs actions of apps you connected in Zapier, and each tool call costs two tasks on Zapier's plans. It documents nothing specific to social posting or approval. A social media MCP server knows each network's rules, such as caption limits and media types, and returns a result per network.
