X has an official MCP server now.
Here is when to use it, and when not to.
XMCP is real and it can post. It also inherits everything about the X API: a developer account, OAuth app credentials, pay-per-use billing, and no scheduling. OpenTweet is the flat-fee alternative: one hosted URL, no developer account, and 43 tools that post, schedule, thread, and read analytics.

What XMCP does well, and where it stops
XMCP is a clean bridge from your MCP client to the X API, with over 140 operations including posting, likes, reposts, DMs, and lists. But it is a bridge, not a product: you still apply for a developer account, manage OAuth credentials, and pay per API call, and because the X API has no scheduled-posts endpoint, everything publishes the instant your agent calls it. A managed MCP server sits one level higher. It owns the X connection for you and adds the publishing layer the raw API never had: scheduling, threads, an evergreen queue, and analytics.
MCP servers for X, compared
XMCP details from the official X Developer Platform release, June 2026.
Paste one URL. Nothing to install.
OpenTweet runs a hosted MCP server at a single URL, the same setup style as XMCP. Point your client at it with your API key and your agent can post to X. No local process, no developer account, no OAuth.

Frequently asked questions
Can X's official MCP server (XMCP) post tweets?
Yes. XMCP exposes createPosts along with likes, reposts, deletes, DMs, and list management, over 140 operations from the X API. The catch is not capability, it is cost and setup: you need an X developer account, app credentials, and pay-per-use API billing, and there is no scheduling.
Can XMCP schedule a tweet for later?
No. The X API has no scheduled-posts endpoint, so XMCP publishes the moment your agent calls it. If you want a queue, best-times scheduling, threads, or evergreen recycling, that layer has to live somewhere else. That layer is what OpenTweet provides.
What does XMCP cost?
XMCP itself has no subscription, but every call bills against X API pay-per-use pricing, and X caps usage at 2 million post reads per month before requiring an Enterprise agreement. OpenTweet is a flat $11.99 per month with posting, scheduling, and analytics included.
When should I use XMCP instead of OpenTweet?
Use XMCP when you already have an X developer account and need the raw API surface: DMs, lists, blocking, follower management. Use OpenTweet when the job is publishing: post, schedule, thread, recycle evergreen content, and read your account analytics for a flat fee with no developer account.
Do the open-source Twitter MCP servers post?
Some do, but they are self-hosted. You run the process yourself and supply your own X developer credentials and OAuth tokens. That is more setup and maintenance than a managed server, and several have broken write paths after X's API changes.
Which MCP clients does OpenTweet work with?
Claude, Cursor, Claude Code, and any MCP-compatible client, over a hosted URL or the npm package. It exposes 43 tools for posting, scheduling, evergreen recycling, analytics, and multi-account management.
