Background & analysis
On November 1, 2026 at 13:21, the Chinese developer platform Juejin published a tutorial titled "MCP 开发实战：把你自己的后端 API 接入 Agent". The article presents a hands-on approach to writing an MCP Server in TypeScript, claiming the implementation takes under 100 lines of code and connects a self-built backend API to ChatGPT and Claude.
Beyond the basic integration, the tutorial also lays out four design principles for building tools aimed at AI agents, a multimodal approach to automated login through image reading, and a list of five practical pitfalls to avoid.
Only this single report has been collected so far, so there is nothing further to corroborate regarding the code's reliability, its real-world adoption, or any community feedback. The situation currently stands at the stage of the tutorial having been published.
