Building an MCP-Enabled Agent in 6 Lines with mcp-use
~12 min read
mcp-use removes the low-level protocol plumbing — an MCP client, server connection, tool discovery, and LLM wiring all come together in about 6 lines of code.

Key points
- •mcp-use removes the need to hand-implement MCP's capability handshake, transport layer, and tool-schema wiring
- •It sets up the MCP client, connects to one or more servers, discovers tools, and exposes them to the LLM automatically
- •The book's example builds a working MCP-enabled agent in about 6 lines of code, connecting to a Playwright server
- •Once set up, the LLM requests tool calls naturally during reasoning — mcp-use handles execution and streaming
- •This compresses substantial protocol boilerplate into a small setup step, keeping developer attention on application logic
