# Build with AI

> Connect AI clients and agents to Fluence, and use the Fluence docs with LLMs.

To let Claude Code, Cursor, Codex, or another MCP client manage CPU virtual machines with a Fluence API key, start with [Connect an AI client through MCP](https://fluence.dev/docs/build_with_ai/mcp.md). The [MCP server reference](https://fluence.dev/docs/build_with_ai/mcp_reference.md) lists the tools, permissions, limits, and errors. An agent that pays with its own wallet can fund an account over HTTP. See [Pay with x402](https://fluence.dev/docs/build/api/x402.md).
