Context7 setup: MCP documentation and rules

In this Ukrainian-language tutorial with English captions, Context7 supplies library documentation to a coding assistant through MCP. The speaker explains why this can help: a model may know a popular library such as React but still confuse particular API calls or parameters. He reports that documentation lookups help when an assistant starts using a library incorrectly.

The setup discussion covers registering for an account, getting a key and installing the MCP integration. The speaker describes installation through a command or a Claude plugin. He also says he often asks the assistant to install Context7 itself or guide him through the process. Cursor, Claude Code and Codex are among the supported clients named in the tutorial description.

Installation does not mean the assistant will consult documentation for every request. The speaker recommends explicitly asking it to use Context7 when a task needs closer reference to the docs, particularly after an incorrect answer.

The final section explains how rules can request documentation automatically under chosen conditions. Examples include uncertainty about an API, a request for a specific library version, or a library with recent major changes. This is a documentation setup tutorial; it does not demonstrate how to run models locally or establish offline support.
