Setup Context7 Mcp

It walks you through three configuration options (project-shared, project-local, or global), checks if Context7 is already installed, and then updates your CLAUDE.md file with relevant doc IDs based on your project structure. The smart bit is that it parses your codebase to figure out what frameworks you're using, or asks you directly if the project is empty. Saves you from manually hunting down the right documentation IDs and keeps your context configuration in sync with your actual dependencies. Worth using if you regularly spin up projects with different tech stacks.
