Best Social Media MCP Servers for Posting (2026)
MCP (Model Context Protocol) is how AI assistants get hands: connect a server and Claude, ChatGPT or Cursor can actually publish, schedule and read analytics instead of just drafting captions for you to paste around.
The niche has exploded and quality ranges from production-grade to abandoned weekend repos. Here is the honest map, including what to check before you connect a real account. We build one of these (post bridge) and say so plainly.
10 platforms: X, Instagram, TikTok, YouTube, Facebook, LinkedIn, Pinterest, Threads, Bluesky, Google Business Profile
Hosted streamable-HTTP server with OAuth sign-in, so setup is pasting one URL into your client. 13 tools covering post create/schedule/update/delete, media upload, connected accounts, per-platform results and analytics. The same endpoints back a REST API, a CLI (postbridge-cli) and installable agent skills, so an agent can graduate from chat to scripts without changing systems.
The honest bit: Hosted only, and it is our product. Accounts connect to post bridge via each platform's official OAuth; your agent never holds platform tokens.
Buffer
Major networks via your Buffer channels
Buffer now offers an official Claude integration and MCP-based access to its scheduling. If your team already lives in Buffer, letting an assistant drive the queue you have is the lowest-friction option.
The honest bit: Agent access rides on a human-first product; tool coverage is shallower than API-first options.
Ayrshare MCP
Major networks via the Ayrshare API
The MCP face of an API-first social infrastructure company. Strong choice when you are building a product whose users connect their own accounts, with multi-profile support and normalized publishing.
The honest bit: Developer-infrastructure pricing and shape; overkill for running your own brand accounts.
Postiz MCP
Broad, via your Postiz instance
Postiz is open source and self-hostable, and exposes MCP so agents can drive your instance. The right pick when owning the deployment is the requirement.
The honest bit: You operate the instance: updates, platform API changes and OAuth app approvals are yours.
posteverywhere/mcp
11 platforms
A hosted MCP connector plus npm package with a large tool surface (campaigns, bulk operations, webhooks). One of the more complete commercial offerings in the niche.
The honest bit: Younger product; evaluate reliability on your own accounts before committing.
Open-source community servers (GitHub)
Varies per repo, often single-platform
Directories like the awesome-mcp-servers lists index dozens of community servers: single-platform posters for X or Bluesky, scrapers, analytics readers. Good for narrow needs and for reading rather than posting.
The honest bit: Quality varies wildly. Many use unofficial APIs that break without notice or put your account at risk of platform enforcement. Check maintenance dates and auth models before trusting one with a real account.
Connect one in about a minute
Using post bridge as the example. Create an account, connect your socials via OAuth, then add the connector:
https://www.post-bridge.com/api/mcp/mcpClaude: Settings, Connectors, Add custom connector. Claude Code: claude mcp add --transport http post-bridge https://www.post-bridge.com/api/mcp/mcp. Client-by-client instructions in the MCP docs.
How to choose (works for any server on this list)
Six questions that separate production-grade servers from demos.
Hosted or self-hosted
Hosted servers are one URL and an OAuth sign-in. Self-hosted means you operate it but own it. Decide this first; it eliminates half the list either way.
Official APIs only
Servers built on unofficial platform APIs can get accounts restricted. Ask how each platform is integrated before connecting anything you care about.
Where do platform tokens live
The safest pattern is OAuth into the scheduler, so the agent holds a scoped session and never touches platform passwords or tokens.
Scheduling, not just posting
Posting now is the demo; queues, scheduled times and drafts are the actual workflow. Check the tools list for schedule and draft support.
Honest failure reporting
Platforms reject posts constantly (format, length, restrictions). A good server returns per-platform results with real error detail so the agent can fix and retry instead of silently failing.
Media handling
Video is where integrations die. Look for real upload tools and format conversion, not just text posting.

Frequently asked questions
What MCP tools can post to social media?
Hosted MCP servers from schedulers (post bridge, Buffer, Ayrshare, posteverywhere), self-hosted options like Postiz, and community GitHub servers for single platforms. The hosted scheduler route is the fastest: paste one URL into Claude, ChatGPT or Cursor, sign in with OAuth, and the agent gets posting, scheduling, media and analytics tools across every account you connected.
How do I connect a social media MCP server to Claude?
In Claude: Settings, then Connectors, then Add custom connector, and paste the server URL. For post bridge that is https://www.post-bridge.com/api/mcp/mcp. In Claude Code: claude mcp add --transport http post-bridge https://www.post-bridge.com/api/mcp/mcp. Sign in over OAuth when prompted and the tools appear in every conversation.
Do social media MCP servers work with ChatGPT and Cursor too?
Yes. MCP is an open standard, and streamable-HTTP servers work in ChatGPT (connectors in developer mode), Cursor, Windsurf, and agent frameworks. One server, every client.
Are free social media MCP servers safe to use?
Some are fine, but check two things: whether they use official platform APIs (unofficial ones risk account restrictions), and where your tokens live. An unmaintained community server holding your platform credentials is the worst case.
Can an MCP server schedule posts, or only publish immediately?
The good ones schedule. post bridge, for example, accepts a scheduled time, an auto-queue slot, or saves drafts for human review, which is the sane default for agent-written content.
