Best Social Media MCP Servers for ChatGPT and Claude (2026)

The best social media MCP server is the one that actually publishes to your networks from the assistant you already use: Buffer for a free start, Postiz for the widest list of platforms, Post Bridge for many accounts at one price, Kreatoai for posting plus an agent that answers your direct messages, and Ayrshare or Outstand if you are building your own product. Every fact below was read on each tool's official page on October 29, 2026.

In this guide:

• what a social media MCP server is, in plain words;
• what to check before you connect one;
• eight servers compared, with what each does best, its limit and its price;
• how to add a server in Claude and in ChatGPT, step by step.

What a social media MCP server is

MCP stands for Model Context Protocol. Picture a standard plug: on one side your assistant (ChatGPT, Claude, Cursor, Claude Code), on the other a service, and in between a server that exposes a few tools the assistant can call, such as "list my accounts", "create a post" or "cancel this post".

A social media MCP server is simply that plug for your Instagram, TikTok, LinkedIn or Facebook accounts. You write "schedule this for Thursday at 9 a.m. on LinkedIn", the assistant picks the matching tool, and the server sends the post through the network's official interface. You never paste a password into the chat: the accounts are connected once, in the tool's own dashboard or through the network's login screen.

The catch most lists skip is that many servers stop short of publishing. Some only read public data, others only draft. Before anything else, check that the server you pick has a tool that creates and schedules a post.

What to check before you connect one

Six questions sort the field quickly.

1. Networks. Does it cover the networks you actually post to, and the account types you have? A LinkedIn company page and a LinkedIn personal profile are not the same thing for every tool.
2. ChatGPT and Claude. Is it listed in the official directories, or do you add it by hand as a custom server? A directory listing means a few clicks; a custom server means an address to paste and, in ChatGPT, a plan that allows it.
3. Sign-in. OAuth (a consent screen) or an API key to copy? OAuth is simpler and safer for a chat assistant; a key suits scripts.
4. Scheduling and edits. Can the assistant schedule, move and cancel a post, and tell you whether it went out?
5. Media. Instagram and TikTok need a photo or a video for every post. Check how the server receives your files.
6. Price. The connection is usually free; the bill lives in the plan behind it. Look at what the free plan or trial includes, because some trials exclude the MCP server.

The best social media MCP servers, by use case

Buffer: best for a free start

Buffer says its MCP access is included on every plan, even Free. Your assistant can create and schedule posts, manage the queue, save ideas and check your connected channels. Posts land in your Buffer queue as drafts or scheduled posts, so you can review them before they go live. In Claude, Buffer is a community connector in the directory; for ChatGPT, its integration page describes a custom MCP server.

• Limit: the price is per channel, so the bill grows with every account you add.
• Price (as of October 2026): free plan with 3 channels and 10 scheduled posts per channel; Essentials at $5 per channel per month billed yearly, with a 14-day trial.

Comparing it to other tools? See our Buffer alternative page.

Postiz: best for the most platforms

Postiz posts to more than 30 platforms, from Instagram and TikTok to Reddit, Discord and Mastodon. It has an official connector in the Claude directory and, according to its ChatGPT page, an app in the ChatGPT directory. Sign-in goes through OAuth with your Postiz account. One nuance: the directory connector leaves out image and video generation, which you get by adding Postiz's custom link instead.

• Limit: no free hosted plan; the free route is hosting the open source version yourself.
• Price (as of October 2026): $29/mo for 5 channels, $39 for 10, $49 for 30, $99 for 100, with a 7-day trial.

Post Bridge: best for many accounts at one price

Post Bridge is built for one person marketing a business. It is listed in the Claude connector directory and in the ChatGPT plugin directory, and you approve access on a consent screen. It covers 10 platforms, including X, Threads, Pinterest and Google Business, with unlimited posts on paid plans.

• Limit: no free plan, only a 7-day trial; team members come with the higher plan.
• Price (as of October 2026): Marketer at $39/mo for 15 accounts, Operator at $99/mo for 99 accounts, MCP and API included.

Kreatoai: best for posting and answering DMs from one tool

Kreatoai is listed in the Claude connector directory and in the ChatGPT plugin directory: you find it, connect, and approve access, with no key to copy. For Claude Code, Cursor or any client that takes a remote MCP address, one URL does it: https://api.kreatoai.com/mcp. It publishes to Instagram, Facebook Pages, TikTok, LinkedIn personal profiles, YouTube Shorts, Bluesky and Google Business, now or at a set time, on the account you name. If no network is connected yet, the assistant can hand you a link to connect one without leaving the conversation. Beyond publishing, on paid plans, an AI agent answers your Instagram and Messenger direct messages with what your business taught it, and hands over to a person when a question goes beyond its scope.

• Limit: no X, no Threads and no Pinterest for now, and LinkedIn personal profiles only, not company pages. From the assistant, it reads neither your analytics nor your direct messages.
• Free option: a free plan with 10 posts a month, no card. See how it connects to Claude and to ChatGPT.

Metricool: best if analytics come first

Metricool is an analytics tool with publishing on top: competitor tracking, reports, an inbox and a link in bio. Its site links to a connector in the Claude directory and to one in ChatGPT, and the Metricool MCP is part of the free plan, with limits.

• Limit: the free plan excludes LinkedIn and X and stops at 20 posts a month; X is a paid add-on on every plan.
• Price (as of October 2026): free for 1 brand; Starter from $20/mo billed yearly ($25 monthly) for up to 5 brands.

Blotato: best for creating the content as well

Blotato pairs publishing to 9 platforms (including X, Threads and Pinterest) with AI images, videos and voiceovers, plus comment and DM automations on Instagram and Facebook. Its MCP server signs in through OAuth in Claude's apps; its Claude Code guide gives the address.

• Limit: there is no free plan, and the 7-day trial excludes the API and the MCP server: creating an API key ends the trial and starts the paid plan.
• Price (as of October 2026): Starter at $29/mo for 20 accounts.

Ayrshare: best for SaaS builders

Ayrshare is a social media API for products that post on behalf of their users. Its Action MCP server, at https://api.ayrshare.com/mcp, lists 33 tools: publish, history, analytics, comments, direct messages and profiles. It authenticates with your API key and enforces the same rules as the REST API. Mind the difference with its separate documentation MCP, which only searches the docs and posts nothing.

• Limit: priced for companies; client sub-profiles need the Business plan.
• Price (as of October 2026): Premium at $149/mo for one profile; Launch at $299/mo with a 28-day trial; Business from $599/mo.

Outstand: best for a usage-based API

Outstand is a unified API for 12 platforms, priced by post rather than by account. Its MCP server exposes 28 tools to Claude, Cursor or any MCP client, set up with an API key and a configuration snippet.

• Limit: X, Google Business, Vimeo and Reddit require you to register your own developer app with each platform first.
• Price (as of October 2026): $19/mo including 3,000 posts, then $0.007 per post up to 10,000.

Planable vs Buffer vs Hootsuite for MCP

This question comes up often, so here is the short answer, read on each pricing page as of October 2026. Buffer includes its MCP server on every plan, Free included. Planable lists an MCP connector on its Basic, Pro and Enterprise plans (from $33 per workspace per month) and its public API from Pro; its free plan covers your first 50 posts in total. Hootsuite's plans page presents its own assistant, Wisdom, but mentions no MCP server or API, with plans from $99 per user per month billed yearly.

Already living in Zapier, Make or n8n? Each can expose your own workflows to an assistant through MCP, but nothing posts until you build the posting step yourself. A dedicated server saves that work.

How to add a social media MCP server to Claude

Two paths, described by Anthropic's help center and by the tools' own setup pages.

From the directory. Open Customize, then Connectors, browse or search for the tool, and click Connect. Sign in to the tool and approve access. No address to copy.

As a custom connector. On Pro and Max:

1. Go to Customize, then Connectors.
2. Click + Add, then Add custom connector.
3. Enter a name and the server's remote MCP URL, then click Continue.
4. Review the detected authentication settings, click Continue, then Add.

Anthropic notes that custom connectors are available on Free, Pro, Max, Team and Enterprise, with one custom connector on Free. On Team and Enterprise, an owner adds it under Organization settings, then Connectors, and each member then connects individually. In a chat, the + button at the lower left, then Connectors, turns each one on or off.

In Claude Code, the same address goes in one command, for example claude mcp add --transport http kreatoai https://api.kreatoai.com/mcp, then /mcp to sign in.

A word of caution from the same page: custom connectors are not verified by Anthropic. Connect only servers you trust, review the permissions you grant, and be careful with "Allow always" on tools that publish.

How to add a social media MCP server to ChatGPT

From the directory. According to OpenAI's help center, open Settings, then Plugins, select the app, click Install plugin, then Connect and approve access. In a conversation, mention it with @ or pick it from the + menu. ChatGPT may ask for approval before an action: read the request before you confirm.

As a custom MCP server. The steps from OpenAI's page on custom MCP servers:

1. Go to Plugins.
2. Select the plus button, then Add custom MCP server.
3. Enter a name and, optionally, a description.
4. Under Connection, enter the server's public HTTPS MCP address.
5. Configure authentication, review the risk warning and check I understand and want to continue.
6. Select Create as a plugin, then review the discovered tools.

Developer Mode is no longer needed first, so older tutorials that ask for it are out of date. The availability is narrower than in Claude: full MCP support is for ChatGPT Business and Enterprise/Edu on the web, Pro can connect custom servers with read and fetch permissions only, which cannot publish, and custom servers cannot be connected on mobile. That is why a server listed in the ChatGPT directory matters if you post from ChatGPT. For an Instagram walkthrough, see how to connect ChatGPT to Instagram.

Key takeaways

• A social media MCP server lets ChatGPT or Claude publish and schedule on your accounts; check first that it publishes, not only drafts.
• Pick by your networks: Postiz covers the most, Buffer, Post Bridge and Blotato add X, Threads and Pinterest, Kreatoai covers seven networks and adds an agent for direct messages.
• A listing in the Claude and ChatGPT directories saves you the custom setup, and in ChatGPT a custom server needs a Business or Enterprise/Edu plan to write.
• OAuth sign-in suits chat assistants; an API key suits developers who build their own agents.
• The connection is free almost everywhere; the plan behind it is what you pay, and some trials exclude the MCP server.
