<objective> Query up-to-date documentation and code examples for any programming library or framework via the Context7 MCP server. No authentication required. Two-step process: resolve the library ID, then query docs. </objective> <process>

Step 1: Resolve Library ID

Find the Context7 library ID for the library you need:

bash

mcporter call 'context7.resolve-library-id(query: "how to use React hooks", libraryName: "react")' --output json

This returns matching libraries ranked by relevance. Pick the libraryId from the best match (format: /org/project).

Step 2: Query Documentation

Use the resolved library ID to fetch docs:

bash

mcporter call 'context7.query-docs(libraryId: "/vercel/next.js", query: "how to set up middleware for authentication")' --output json

Common Examples

bash

# React hooks docs
mcporter call 'context7.resolve-library-id(query: "React hooks", libraryName: "react")' --output json
mcporter call 'context7.query-docs(libraryId: "/facebook/react", query: "useEffect cleanup patterns")' --output json

# Next.js routing
mcporter call 'context7.resolve-library-id(query: "Next.js app router", libraryName: "next.js")' --output json
mcporter call 'context7.query-docs(libraryId: "/vercel/next.js", query: "app router dynamic routes")' --output json

# Python library
mcporter call 'context7.resolve-library-id(query: "pandas dataframe", libraryName: "pandas")' --output json
mcporter call 'context7.query-docs(libraryId: "/pandas-dev/pandas", query: "merge dataframes on multiple columns")' --output json

</process> <tips> - Always call `resolve-library-id` first unless you already know the exact library ID (format: `/org/project`). - Do not call either tool more than 3 times per question. Use the best result you have. - No authentication required — this server works out of the box. - The `query` parameter in both tools should describe what you're trying to accomplish, not just a keyword. - Use `--output json` to parse results programmatically. </tips>
