That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs. ```txt Implement basic authentication with Supabase. use library /supabase/supabase for API and docs. ``` The slash syntax tells the MCP tool exactly which library to load docs for. ## Specify a Version To get documentation for a specific library version, just mention the version in your prompt: ```txt How do I set up a Next.js 16 proxy? use context7 ``` Context7 will automatically match the appropriate version.
