Can Claude post to Twitter (X)?

Yes. Claude can post to X through an MCP connector. Claude has no built-in X connection, so you add one by connecting an MCP server that holds your X account.

OpenTweet is a Twitter/X scheduler and posting API with a hosted MCP endpoint. Paste one URL into Claude, connect your X account once, and Claude can post, schedule, and thread without an X developer account.

How do I connect Claude to X?

1

Add the MCP endpoint in Claude

In Claude Desktop, open Settings, then Connectors, and add a custom MCP server. Paste this URL. Claude Code, Cursor, Windsurf, Cline, and OpenClaw use the same URL.

mcp endpoint
mcp.opentweet.io/mcp
2

Connect your X account once

Sign in to OpenTweet and connect your X account with one OAuth click. OpenTweet holds the connection, so you never open the X developer portal. If your client uses a JSON config file instead of a UI, the block looks like this.

claude_desktop_config.json
{
  "mcpServers": {
    "opentweet": {
      "url": "https://mcp.opentweet.io/mcp"
    }
  }
}

Ask Claude to post

Tell Claude what to tweet. It calls the post tool and the tweet goes out from your account. Ask it to schedule for later and it uses the schedule tool instead. There are 36 tools in total, covering posting, threads, scheduling, evergreen queues, and analytics.

Where the official X MCP is the better pick

X's own MCP server is first-party, so it carries direct X trust and can reach full-archive search. If you mainly need heavy reading and search from Claude, it is a fair choice. For posting cost, no developer account, and scheduling, OpenTweet wins.

Frequently asked questions

Can Claude post to Twitter (X) on its own?

Not by default. Claude has no built-in connection to your X account. It can write a tweet as text, but to actually publish it you connect an MCP server that holds your X account. Once connected, Claude calls a post tool and the tweet goes out from your account.

How do I connect Claude to X?

Open Claude Desktop (or any MCP client), go to Connectors or MCP settings, and add the hosted MCP endpoint mcp.opentweet.io/mcp. Sign in to OpenTweet and connect your X account once. Claude then has 36 tools to post, schedule, thread, and read analytics.

Do I need an X developer account for Claude to post?

No, not with OpenTweet. OpenTweet holds the X connection for you, so you never touch the X developer portal or enroll an app in billing. The official X MCP server does require your own developer app plus pay-per-use billing.

Can Claude schedule tweets, not just post now?

Yes, through OpenTweet. You can ask Claude to schedule a tweet for a specific time or add it to your queue, because scheduling is one of the MCP tools. The official X MCP posts immediately only and cannot schedule.

Which Claude apps work with this?

Any MCP client works: Claude Desktop, Claude Code, Cursor, Windsurf, Cline, and OpenClaw. You paste the same URL, mcp.opentweet.io/mcp, into whichever client you use.
