X (formerly Twitter) just dropped MCP servers for both the X API and their developer documentation and they work with any MCP-compatible AI tool. Let's see what they can do and build a Spring AI client that connects to both servers.

In this video, we explore the brand-new X MCP servers for docs and the live X API. We start by reviewing the official announcement and documentation, then plug the docs server into Claude AI for a quick test. Finally, we build a full Spring Boot 4.1 + Spring AI 2.0 MCP client app with two demos: querying X API documentation and searching real-time posts on any topic, all powered by AI tool calling.

- Understand the two X MCP servers: one for X API documentation and one for the live X API endpoints
- Learn how to plug a remote MCP server into Claude AI (or any MCP-compatible client) with zero setup
- Build a Spring Boot 4.1 MCP client using Spring AI 2.0 and Anthropic Claude
- Configure streamable HTTP MCP connections and bearer token authentication in application.yaml
- See AI tool calling in action — watch the model decide which MCP tools to invoke automatically

X (formerly Twitter) released MCP servers for its API and developer documentation. This walkthrough shows how to build a Spring AI MCP client using Spring Boot 4.1 and Spring AI 2.0 that connects to both X MCP servers. The docs server requires no authentication and lets an LLM query up-to-date X API documentation. The API server requires a bearer token passed via an MCP client customizer, enabling the agent to search posts, look up users, and retrieve trends. The tutorial covers project setup, YAML configuration for streamable HTTP MCP connections, creating a ChatClient bean with tool callback providers, and two REST controllers demonstrating each server.
