# Introduction

The Xerberus MCP connects your AI agent to Xerberus. One MCP, two plans: Club and Enterprise.

The Xerberus MCP is one server your AI agent connects to. Once it is connected, you ask in plain language and the agent calls the tools it needs. It works with any client that supports remote MCP servers, including Claude Code, Claude Desktop, Cursor and Codex.

What your agent can do depends on your plan.

| Plan                 | Club                                                                           | Enterprise                                                                         |

### One endpoint, your key decides

Both plans use the same endpoint. Your key carries your plan, and your agent sees the tools that plan includes.

| Endpoint | `https://mcp.xerberus.io/framework/mcp` |
| -------- | --------------------------------------- |
| Header   | `X-API-Key: <your key>`                 |

### Where to start

* **Club:** Become a member, then Get your key and Connect your agent.
* **Enterprise:** Enterprise plan.
