Yes, with just 3 lines of core code, you can write an AI Agent client.
No need to worry about network protocols, troublesome OAuth 2.1 authentication flows, or complex state management anymore.
One library solves all the above problems, and that library is use-mcp, just released by Cloudflare.
Previously, developing an MCP client required facing three major challenges:
MCP needs to support multiple transport methods like SSE or streamable HTTP simultaneously, so clients must manually implement a complex set of logic to handle integration.
The latest MCP adopts the industry's most secure OAuth 2.1 protocol. But you have to manually write the complete flow from scratch, including handling authorization server callbacks, writing automatic token renewal logic, and so on - it's tedious, boring, and error-prone.
Finally, there are various MCP network connection boundary issues - determining connection status, disconnections, automatic retries - you have to maintain a whole bunch of state management and handle edge case errors.
