X(Twitter) MCP server enables Claude chat users to create, manage, and publish X/Twitter posts directly from Claude. It supports composing single tweets and threads, saving drafts, and publishing or deleting drafts from within Claude. The server can be installed automatically via Smithery or manually, requiring UV to run locally and a claude_desktop_config.json with the appropriate command, directory, and environment variables. To operate, users must supply their X API credentials (API key and secret, access token, and access token secret) in the environment, and configure the path to the MCP repository. The README provides usage examples such as tweeting a message, creating a thread, showing drafts, publishing drafts, and deleting drafts. Setup steps include installing UV, creating the claude_desktop_config.json, obtaining X API credentials (from X API Developer Portal, with Read/Write permissions and Web App type, callback URL http://localhost/), updating the config, and restarting Claude. Troubleshooting advises ensuring UV is installed, using the full path if necessary, verifying credentials, and confirming the configured path matches the repository location.
