Context7 MCP Guide

About Context7

Context7 is a repository of LLM-accessible documentation libraries for your coding agent to read.

The hope is that by reading the documentation, there'll be less hallucinations.

Sadly, LLMs tend to be a bit arrogant and pompous, so they don't read the f*cking manual even if you beg them to.

Context7 gives you the ability to beg them to.

Finding & Using Libraries (docs)

The context7 homepage is a small app that enables searching for libraries.

Using libraries (docs) is triggered by the command:

use library /author/project

Where author and project are variables for routing to the correct resources.

When you open a library, you go to a page like this: SolidJS's Context7 Listing

This page doesn't include the author or project keys you need to indicate the resource.

Those keys are available on the logs tab: SolidJS's Context7 Logs Tab

They're kinda hidden inside the logs:
