Context7 Docs

Context7 Documentation Lookup

Retrieve current documentation and code examples from Context7 using the resolve-library-id and query-docs tools that ship with this extension.

When to use

Reach for these tools whenever a question involves a specific library, framework, SDK, CLI tool, or cloud service. Examples:

• "How do I configure caching in Next.js 16?"
• "What's the syntax for Prisma's findMany with relations?"
• "Show me a working Tailwind v4 install for a Vite app."
• "How do I rate-limit with @upstash/ratelimit?"

Workflow

1. Resolve the library ID. Call resolve-library-id with the library name and the user's question. The tool returns matching libraries with their Context7 IDs (/org/project format), descriptions, snippet counts, and quality scores. Pick the best match — prioritize official sources, name match, and high benchmark scores. 2. Query the docs. Call query-docs with the chosen library ID and the user's question. The tool returns documentation snippets and code examples. 3. Answer. Cite the library ID you used and quote code examples verbatim when relevant.

If the user supplies a library ID in /org/project or /org/project/version format directly, skip step 1 and call query-docs immediately.

Constraints

• Do not call either tool more than 3 times per question.
• Do not pass API keys, passwords, credentials, personal data, or proprietary code as the query argument — it is sent to the Context7 API.
• Authentication uses the CONTEXT7_API_KEY environment variable. Get a key at https://context7.com/dashboard if requests fail with an auth error.
