Input Parameters
libraryId *
Exact Context7-compatible library ID (e.g., '/mongodb/docs', '/vercel/next.js', '/supabase/supabase', '/vercel/next.js/v14.3.0-canary.87') retrieved from 'resolve-library-id' or directly from user query in the format '/org/project' or '/org/project/version'.
query *
The question or task you need help with. Be specific and include relevant details. Good: 'How to set up authentication with JWT in Express.js' or 'React useEffect cleanup function examples'. Bad: 'auth' or 'hooks'. The query is sent to the Context7 API for processing. Do not include any sensitive or confidential information such as API keys, passwords, credentials, personal data, or proprietary code in your query.

About Query Docs

Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework. You must call 'resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query. IMPORTANT: Do not call this tool more than 3 times per question. If you cannot find what you need after 3 calls, use the best information you have.

Query Docs costs $0.01 per call on xpay. No subscription, no minimums. Pay only for the calls you make. New accounts get $5 in free credits.

Connect the Context7 MCP endpoint to your client — Claude Code: claude mcp add --transport http context7 "https://context7.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"; Cursor/Windsurf/Cline/VS Code: same URL in mcp.json. The agent will see query-docs as a callable tool with the input schema and run it directly. (Unified across all providers: https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY, then xpay_run with toolPath context7/query-docs.)

Yes — that's exactly what xpay is for. You don't need a Context7 account or API key. Sign up at xpay.tools (Google or email), get $5 free credit, and run Query Docs immediately. Billing flows through your xpay balance.

Query Docs accepts 2 input parameters: libraryId, query. See the input schema and runnable form on this page for details and to test live.
