X (Twitter) MCP Server
An X MCP server, still widely searched as a Twitter MCP server, gives an AI agent tools for X so a model can publish to your account instead of only drafting posts. Point Claude, Cursor, or any MCP client at Outstand's server and the agent can post, attach images or video, reply, retweet, quote, and read engagement metrics. Everything runs through the official X API using your own X app credentials.
Calling it from your own code instead of an agent? The same account works through our X API.

First post in minutes.
The server URL is https://mcp.outstand.so/mcp. Paste it into your client and connect X (Twitter).
- 01Create an X developer account and an app in the X developer portal, then copy its OAuth 2.0 client ID and secret. X is the one network where you bring your own keys.
- 02Add those credentials to Outstand with create_social_network, or paste them in the dashboard. Your agent can do this step too.
- 03Connect your X account through the OAuth link, which now runs against your own X app.
- 04Add https://mcp.outstand.so/mcp to your MCP client and ask it to post.

Does X have an official MCP server?
Yes - since 30 June 2026. X runs a hosted MCP server at https://api.x.com/mcp, maintained by the X Developer Platform, and you connect through its open-source xurl bridge, which handles the OAuth and auto-refreshes the token. There is also a self-hosted server, xdevplatform/xmcp, that you clone and run yourself.
That moves the question from whether there is an official one to what it does. The hosted server's published tool list is read-heavy: fetch posts and their likers, reposters and quoters, full-archive post search, user lookup and timelines, bookmarks, news and trends, plus Articles, which it can draft and publish. Publishing an ordinary post with media lives in the self-hosted xmcp repo instead (createPosts, and the three-step initializeMediaUpload / appendMediaUpload / finalizeMediaUpload), which means running the process yourself; its README notes tokens are "kept in memory only for the lifetime of the server process", so the connection does not survive a restart. Neither one schedules.
Both official routes need exactly what we need: your own X developer app, on whatever API tier it sits on.
What Outstand adds on top of your own X credentials is the part neither official route covers: tokens stored and refreshed so a connection survives a restart, media upload, scheduling, and the same 28-tool surface across the other 11 networks you post to. If all you need is read access to X from an agent, the official hosted server is the shorter path, and we will say so.
X is the one platform here where the bill moves with usage, so it is worth knowing what posting to X costs per request.
Choosing a X (Twitter) MCP.
Five realistic ways to give an agent access to X, and what each one actually costs you.
| Approach | Setup time | Auth | Reliability | Compliance |
|---|---|---|---|---|
| Official X MCP - hosted (api.x.com/mcp) | Minutes, plus your own X developer app | Your own X app via X's xurl OAuth bridge; token auto-refreshed | Maintained by X. Read-heavy scope: no ordinary post creation, no media upload, no scheduling | Official X API by definition |
| Official X MCP - self-hosted (xdevplatform/xmcp) | Clone and run it yourself, plus your own X developer app | Your own X app; tokens held in memory only for the process lifetime | Maintained by X, but it stops when the process stops, and it does not schedule | Official X API |
| Self-hosted open-source | An hour or two, plus X developer app setup | Your own X app keys, stored and refreshed by you | Breaks when X changes tiers or your token expires | Official X API, if the project is still maintained |
| Directory-listed community server | Minutes to hours, depending on the project | Your own X app keys | Depends on the maintainer. Many predate the current API tiers | Usually the official API. Check before trusting it |
| Hosted API-based (Outstand) | Minutes once you have X app keys | Your own X app keys (BYOK), stored encrypted and refreshed for you | Maintained against the official API, token refresh handled | Official X API. No scraping, no session cookies |
Authentication: X is the one platform where you bring your own keys
X is the single network where Outstand requires your own API credentials. Every other platform we support ships with Managed Keys included, and this exception is deliberate rather than a gap.
The reason is X's API pricing. If we bundled X access behind our own app, X's per-tier costs would land inside a flat $19/month plan, and the only way to survive that would be to price for the worst case or cap you in ways you could not predict. With your own keys, your X usage sits on your own tier: you see exactly what it costs, you get that tier's rate limits rather than a share of somebody else's, and your cost of goods stays forecastable as you scale.
What you need is an X developer account and an app with OAuth 2.0 credentials. Store the client ID and secret with create_social_network, connect your account through the OAuth link, and everything after that works exactly like the other networks. The credentials stay yours and stay portable, and the X setup guide in the docs walks through the developer portal step by step.
X (Twitter) specifics.
- ✓Media rules follow X: up to 4 images, or one GIF, or one video, and the types cannot be mixed in a single post.
- ✓Threads are not chained yet. Each post publishes as a single post on X, so an agent that wants a thread should publish and then reply.
- ✓Retweets and quote tweets both work through repost_post. Pass a quote to add commentary, or leave it out for a plain retweet.
- ✓Post analytics return likes, replies, retweets, and impressions. Time-ranged account engagement needs X Analytics on a Premium tier, so it comes back empty rather than guessed.
What this MCP doesn't do.
This is a publishing server, not a listening one. It does not scrape tweets, search the firehose, pull follower lists, automate DMs, or touch X Ads. Analytics cover posts you published through Outstand, not other people's content across X. If you need monitoring or lead scraping, this is the wrong tool.
Frequently asked questions.
Does X have an official MCP server?
Yes, since 30 June 2026. X runs a hosted MCP server at https://api.x.com/mcp, connected through its open-source xurl OAuth bridge, and it publishes a self-hosted one as xdevplatform/xmcp. The hosted server is read-heavy: posts and their likers, reposters and quoters, full-archive search, user lookup, bookmarks, news and trends, plus drafting and publishing Articles. Creating an ordinary post with media lives in the self-hosted repo instead, and neither one schedules.
Is an MCP server a real server?
Yes, though it does not have to be one you run. An MCP server is a process that exposes tools to a model over a defined protocol, and it can be something you start on your own machine or something somebody else hosts for you. Outstand's is hosted: https://mcp.outstand.so/mcp is an HTTP endpoint you point your client at, so there is nothing to install and no process to keep alive.
How do I run an X MCP server?
With Outstand you do not have to run one. Adding it is a single command - claude mcp add -t http outstand https://mcp.outstand.so/mcp - and the endpoint stays up whether your machine does or not. The alternative is X's self-hosted xdevplatform/xmcp, which you clone, configure with your own X app, and keep running as a process; its tokens are held in memory only for the lifetime of that process, so the connection ends when the process does.
Why do I need my own X API keys?
Because X charges for API access in a way that cannot be bundled into a flat plan without either overpricing everyone or capping you unpredictably. Bringing your own keys means your X usage runs on your own tier: predictable cost, that tier's rate limits, and credentials that stay yours. X is the only network where Outstand requires this - everywhere else, Managed Keys are included.
What X API tier do I need?
You need an X developer app with OAuth 2.0 credentials. Historically the free tier was enough for posting, and our X setup guide documents the tiers and their rate limits. X has been changing its access model for new developers, so check the current terms in the X developer portal before you commit to a volume.
Can I use the X API for free?
There is a free tier, and historically it has been enough to post from. X has been reworking what new developers get, so read the current limits in the X developer portal rather than an older write-up, and our X API pricing breakdown walks through how the paid tiers compare. Either way that bill is X's, not ours: it sits on your own developer app and is paid directly to X, and the Outstand MCP server is included in your plan.
Can Claude post threads on X?
Not as a single chained call yet. Each post is published as one post on X today, so an agent that wants a thread should publish the first post and then add replies. Chained multi-post threads do work on Threads, where the API supports them natively.
Can it schedule posts on X?
Yes. create_post takes a scheduled time and an agent can queue a post up to 30 days ahead. Scheduling runs inside Outstand rather than on X, and a scheduled post can be cancelled with delete_post before it goes out.
Does it retweet and quote tweet?
Yes, both through repost_post. Passing a quote creates a quote tweet with your commentary on top; leaving it out creates a plain retweet. It can also reply to comments on posts you published through Outstand.
What does it cost?
Outstand is $19/month, 3,000 posts included and the MCP server is included at no extra cost. Whatever X charges for your own API tier is separate and paid directly to X, which is exactly what makes it predictable.
