## Key points
- Yes, but not through X's main hosted MCP server. Its published capabilities cover reading posts, search, users, bookmarks, trends and Articles. Creating an ordinary post is not among them.
- You do not have to take that on trust. The server's own OAuth metadata lists the scopes it can be granted, and post-write is not one of them. It cannot be given the authority even in principle.
- There are three official servers, not one. The self-hosted repository does create posts, has no licence, and has not been touched since April. A third server for advertisers launched in August and can also create posts, which nobody has reported correctly.
- The bill is not the sticker price. A plain post costs fifteen thousandths of a dollar. A realistic assistant session, which reads before it writes and confirms afterwards, costs about two and a half times that.
- Add a link and it costs eighteen times the sticker price for one published post, because a post containing a URL is charged at more than thirteen times a plain one.
- What a post with an image costs is genuinely unknowable from X's documentation, and we would rather say so than pick a number.

## FAQ
Q: Can Claude post to Twitter?
A: Yes, through a connector, but not through X's general-purpose hosted MCP server. That server covers reading posts, search, users, bookmarks, trends and Articles, and its published OAuth scopes do not include write access to posts. Posting requires X's self-hosted server, its advertising server, or a third-party connector.

Q: Why can't X's official MCP server post?
A: Its documented capabilities limit writes to bookmarks and publishing Articles, and its OAuth metadata does not list a post-write scope, so it cannot be granted that authority at all. X told a reporter at launch that the tool is not compatible with its write endpoints and cannot be used to post.

Q: How much does it cost for Claude to post to X?
A: A plain post is $0.015 and a post containing a link is $0.200, more than thirteen times more. But a realistic assistant session also reads before it writes and confirms afterwards, which brings a plain post to around $0.036 and a link post with a search step to around $0.275.

Q: Is there a free tier for the X API?
A: Not for new developers. The free tier ended in February 2026 and the model is now pay-per-usage credits with no subscription. Claims that new projects receive $500 in credits refer to a hand-picked closed beta from October 2025, not a standing offer.

Q: What does a post with an image cost on the X API?
A: X does not publish enough to say. Media upload calls have no line item on the rate card, each attached media object reportedly bills as an extra post creation according to a staff answer absent from that page, and whether that surcharge uses the plain or the link rate is undocumented. The honest range is roughly $0.215 to $0.405.

Q: What happens when X API credits run out?
A: Requests are blocked, reads as well as writes, until credit is added. In our own measurement the API returned an HTTP 402 with a credits-depleted problem type, though that status code does not appear anywhere in X's published documentation. Note also that auto-recharge is documented as paused at zero balance.
