# Agent Resources

> Machine-readable files, MCP servers, and resources for AI agents working with the X API

Resources for connecting AI tools to the X API and its documentation.

***

## Use the X API from AI tools

Give your AI agent the ability to call X API endpoints directly.

**MCP Servers** — XMCP exposes 200+ X API endpoints as callable MCP tools. Docs MCP lets agents search and read these docs on the fly.

**OpenAPI Spec** — Machine-readable API definition ([https://api.x.com/2/openapi.json](https://api.x.com/2/openapi.json)) for auto-generating clients or feeding into agents.

## Read X API docs from AI tools

Give your AI agent context on how the X API works.

**llms.txt / llms-full.txt** — Documentation index and full-content Markdown files for LLMs to ingest.

**skill.md** — Capability summary (agentskills.io) that tells agents exactly what actions, parameters, and constraints exist.

**Docs MCP** — Search and read any documentation page directly from your AI assistant via MCP.
