X (Twitter) MCP server: search X from Claude or ChatGPT
This X MCP server lets Claude or ChatGPT search posts, read a profile, pull a user's recent tweets and read the replies to a post. It runs on Lodestone's keys, so you need no X developer account.
Free. No card, no password. We email you a link that sets up your account.
