The 7 Best Social Media MCP Servers for Posting From Claude, ChatGPT and Cursor

An MCP server is what turns a chat assistant into something that can act. Connect one of the best social media MCP servers to Claude, ChatGPT or Cursor and the assistant stops handing you captions to paste and starts publishing, scheduling and reading results on its own. The Model Context Protocol (MCP) is the open standard that makes those tools discoverable, so the same server works in every client that speaks it.

The catch is quality. GitHub is full of "social media MCP" repos with a single commit and a hardcoded token, and several vendors list MCP on a pricing page without documenting a URL. This list only includes servers with a public endpoint or install path we verified in September 2026. We build AdaptlyPost, so it is first, and we say where a competitor is the better fit.

The short version: AdaptlyPost, Buffer, Postiz, Post Bridge, Ayrshare and FeedHive each run a hosted MCP server you connect with a URL and a key. Buffer's is free. AdaptlyPost's is the only one on this list that exposes a per-platform retry tool. Everything else on GitHub is single-platform and unmaintained more often than not.

What is a social media MCP server?

A social media MCP server is a service that publishes a set of tools, such as create_post or list_accounts, over the Model Context Protocol so that an AI client can call them. The client sends a natural-language request, the model picks a tool, the server executes it against the connected social accounts, and the result comes back into the conversation.

Two details separate a usable server from a demo. First, transport: hosted HTTP servers connect with a URL and a header, while stdio servers need a local process and usually a bridge such as mcp-remote. Second, the tool set: a server that only has publish_now cannot schedule, cannot upload media, and cannot tell the agent which platform failed.

Which social media MCP servers are worth connecting?

Six vendor-hosted social media MCP servers are worth connecting in 2026: AdaptlyPost, Buffer, Postiz, Post Bridge, Ayrshare and FeedHive. The seventh entry covers the open-source single-platform servers on GitHub, which are useful for one network and risky for a whole presence.

1. AdaptlyPost MCP

AdaptlyPost hosts its MCP server at https://mcp.adaptlypost.com/mcp over HTTP transport, authenticated with a Bearer adaptly_ key from the API Tokens page. The server exposes 12 tools and is included on every plan, starting at $19 per month for 30 connected accounts across nine platforms.

The 12 tools map to the full posting lifecycle: list_accounts, upload_media, get_upload_urls, create_post, get_post, list_posts, update_post, delete_post, publish_draft, list_post_results, retry_failed_platforms and bulk_schedule_posts. The pair at the end is what an autonomous agent actually needs. list_post_results returns one outcome per platform with the error text, and retry_failed_platforms re-sends only the platforms that failed instead of duplicating the post everywhere else.

Setup in Claude Code is one command:

claude mcp add --transport http --scope project \
  --header "Authorization: Bearer adaptly_your_key" \
  -- adaptlypost https://mcp.adaptlypost.com/mcp

Cursor and Windsurf take the same server as a JSON block in their MCP settings. Claude Desktop only speaks stdio, so it needs the mcp-remote bridge, and the exact config is in the MCP setup guide.

Watch for: AdaptlyPost covers X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest, Threads and Bluesky, and nothing else. No Google Business Profile, Reddit or Mastodon.

2. Buffer MCP

Buffer released its MCP server, public API and CLI together on 27 May 2026, and made MCP available on every plan including the free tier. Buffer's own page puts it plainly: "MCP access is available on every Buffer plan, even Free."

Buffer connects through OAuth sign-in as a custom connector in Claude and ChatGPT, and lists Cursor, Raycast, Perplexity, Notion, Zapier, n8n, Manus and Antigravity as further clients. The tools create posts, schedule them, manage the queue, save ideas and read connected channels and upcoming content.

Watch for: Buffer routes every agent-created post into the queue as a draft or scheduled item for human review. That is the right default for a solo creator and a blocker for an unattended pipeline. The free plan stops at 3 channels. See the Buffer comparison for plan limits.

3. Postiz MCP

Postiz issues each user a personal MCP link in the form https://api.postiz.com/mcp/YOUR_API_KEY, generated from Settings, Developers, Public API. Paste the link as the server URL in ChatGPT, Claude Desktop, Cursor or Claude Code and the tools appear. The MCP server costs nothing beyond the plan.

Postiz cloud starts at $29 per month for 5 channels, and the AGPL source self-hosts for free. The MCP server lets an agent write and schedule posts, attach generated images and video, and target the 30+ platforms Postiz connects, including Reddit, Mastodon, Discord and Slack.

Watch for: Postiz caps the public API at 30 requests per hour, and the MCP server rides on that API. A bulk-scheduling agent will hit the ceiling in minutes. Postiz's docs also ask that "there is always a human in the loop." Read our Postiz alternatives guide if self-hosting is the sticking point.

4. Post Bridge MCP

Post Bridge hosts an HTTP MCP server at https://www.post-bridge.com/api/mcp/mcp with 13 tools covering scheduling, analytics, account management, media and post editing. Auth is OAuth through connector directories or a dashboard API key for self-hosted agents, and MCP is bundled on every plan.

Post Bridge lists Claude, ChatGPT, Cursor, Windsurf, OpenClaw and Hermes as clients and covers 10 platforms, adding Google Business Profile to the same nine AdaptlyPost supports. Plans are $29 for 5 accounts, $39 for 15, $59 for 50 and $99 unlimited.

Watch for: MCP is included, but the plain REST API is a $5 per month add-on. If part of the agent runs as a script, that add-on applies. Our Post Bridge comparison goes through the per-account math.

5. Ayrshare MCP

Ayrshare documents an official MCP server inside its API docs, and community packages on npm and Pipedream wrap the same API with 34 or more tools. The server covers Ayrshare's full API: publishing, analytics, comments, DMs and ads across 14 networks.

Ayrshare's pricing starts at $149 per month for the Premium plan and rises to $299 and $599 for 10 and 30 profiles. The product is built for SaaS platforms that post on behalf of their own users.

Watch for: price and intent. A single creator with a Claude agent pays Ayrshare eight times the AdaptlyPost Creator plan for the same networks. Ayrshare earns its place when you are shipping a product, not running an account.

6. FeedHive MCP

FeedHive advertises an official MCP server, a public REST API and a CLI on its home page, with plans at $19 Creator, $29 Brand, $99 Business and $299 Agency. API and MCP access are bundled rather than sold as an add-on.

FeedHive's differentiator is its automation layer. Conditional posting, recycling and AI writing all sit behind the same API, so an agent inherits them.

Watch for: FeedHive publishes less API documentation than Ayrshare or AdaptlyPost, and no rate limits. Trial the MCP tools you need before committing an agent to them.

7. Open-source community servers on GitHub

GitHub hosts dozens of single-platform MCP servers: X posting servers, LinkedIn servers, Reddit and Bluesky servers, plus unofficial wrappers for Postiz and Ayrshare. They run locally over stdio with your own platform tokens, and they cost nothing.

Watch for: three things before connecting a real account. Check the last commit date. Check that the token is read from an environment variable and never logged. Check whether the repo owner is the platform vendor or a stranger, because an MCP server sees every credential you give it. A weekend repo is fine for one Bluesky account and a bad idea for a client's Instagram.

How do you connect a social media MCP server to Claude?

Connecting a social media MCP server to Claude takes a URL, a key and one config edit. In Claude Code, run claude mcp add --transport http with the server URL and an Authorization header. In Claude Desktop, add the server through the mcp-remote bridge in claude_desktop_config.json. In claude.ai, add it as a custom connector under Settings, Connectors.

Once the server is registered, ask Claude to list connected accounts. If the accounts come back, the tools are live and the next request can be "schedule this to LinkedIn and X on Tuesday at 9am Berlin time." The full walkthrough is in how to post to social media with AI agents.

How should you choose between these MCP servers?

Choose by three questions: does the agent need to publish without a human, does it need per-platform retry, and which networks does it post to. Buffer answers no to the first, so it fits reviewers and not pipelines. AdaptlyPost is the only server on the list with a retry tool. Post Bridge and Postiz win on network count if Google Business, Reddit or Mastodon matter.

Frequently Asked Questions

What MCP servers can post to social media?

AdaptlyPost, Buffer, Postiz, Post Bridge, Ayrshare and FeedHive each run a vendor-hosted MCP server that posts to social media from Claude, ChatGPT and Cursor. AdaptlyPost's server exposes 12 tools at mcp.adaptlypost.com and is included on the $19 plan. Buffer's is free on every plan and routes posts through a review queue.

Do social media MCP servers work with ChatGPT and Cursor too?

Social media MCP servers built on HTTP transport work with ChatGPT, Cursor and any other MCP-capable client, because the protocol is the same in every client. AdaptlyPost, Post Bridge and Postiz document ChatGPT and Cursor setup directly. Clients that only speak stdio, such as Claude Desktop, connect through the mcp-remote bridge.

Are free social media MCP servers safe to use?

Free vendor-hosted servers such as Buffer's are as safe as the vendor's OAuth, because your credentials never leave the vendor. Free community servers on GitHub are only as safe as the repo, because they run locally with your raw platform tokens. Check the last commit, check that tokens come from environment variables, and never connect a client account to an unmaintained server.

Can an MCP server schedule posts, or only publish immediately?

AdaptlyPost, Buffer, Postiz and Post Bridge each schedule posts through MCP as well as publish immediately. AdaptlyPost's create_post tool accepts a scheduledAt timestamp with an IANA timezone, and bulk_schedule_posts queues a batch in one call. Buffer schedules into its queue, where a human can still edit before it goes out.

How many platforms can an AI agent post to through AdaptlyPost's MCP server?

AdaptlyPost's MCP server posts to nine platforms: X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Pinterest, Threads and Bluesky. One create_post call fans out to any combination of those, and list_post_results returns one result per platform so the agent knows exactly which succeeded.
