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?
Add the MCP endpoint in Claude
The hosted endpoint authenticates with your OpenTweet API key in an Authorization header, so add it somewhere that can send one: the one-click installer for Claude Desktop, the config file below, or claude mcp add with a header in Claude Code. Cursor, Windsurf, Cline, and OpenClaw take the same URL and header.
https://mcp.opentweet.io/mcpConnect 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. Your API key goes in the config block, which looks like this.
{
"mcpServers": {
"opentweet": {
"url": "https://mcp.opentweet.io/mcp",
"headers": {
"Authorization": "Bearer ot_your_key_here"
}
}
}
}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 44 tools in total, covering posting, threads, scheduling, evergreen queues, and analytics.
Official X MCP vs OpenTweet for Claude
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?
Add the hosted MCP endpoint https://mcp.opentweet.io/mcp to Claude Desktop (or any MCP client) with your OpenTweet API key as an Authorization header, using the installer, a config file, or claude mcp add. Sign in to OpenTweet and connect your X account once. Claude then has 44 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. Each one takes the same URL, https://mcp.opentweet.io/mcp, plus your API key in an Authorization header.
