Name Title Description
query-docs – Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework.
Input schema

  ],
  "properties": {
    "query": {
      "type": "string",
      "description": "What to look up in the library's documentation, scoped to a single concept. Be specific and include relevant details, but keep each query to one topic — if the user's question spans multiple distinct concepts, make a separate call per concept instead of combining them, unless the question is about how the concepts interact. Good: 'How to set up authentication with JWT in Express.js' or 'React useEffect cleanup function examples'. Bad (too vague): 'auth' or 'hooks'. Bad (too broad): 'routing and auth and caching in Next.js'. 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."
    },
    "language": {
      "type": "string",
      "description": "Programming language the user is writing code in, such as 'Python', 'TypeScript', 'Go', or 'C#'. Ranks code examples in that language first. Leave it out when the language is unknown or does not apply."

      "type": "string",
      "description": "Exact Context7-compatible library ID (e.g., '/mongodb/docs', '/vercel/next.js', '/supabase/supabase', '/vercel/next.js/v16.2.9') retrieved from 'resolve-library-id' or directly from user query in the format '/org/project' or '/org/project/version'."
