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
