What is Context7 MCP?

We all know that writing code with AI clients like Cursor or Claude Code can lead to a never ending loop of bugs.

"You broke it again!", "This is not how you initialize the class, FOCUSSSSS!" <- This used to be me after a whole morning of letting Claude code for me 😅

These bugs often come from a lack of context given to the LLM, for example if you ask it to implement a feature with the Ruby LLM gem, it might not have the latest version of the documentation and suggest an older syntax. The solution? connect the documentation directly in the LLM's chat thanks to Context7 MCP.arrow-up-right

In this library you will find thousands of documentation ready to be used.

All the documentation I code with is related to the Lightning Rails Stack:

  • Ruby on Rails

  • Lightning Rails (Of course ☺️ )

  • Lucide rails

  • Tailwind CSS

  • DaisyUI
