Context7

Library documentation lookup for coding assistance (by Upstash)

Available Tools

• resolve-library-id: Resolves a package/product name to a Context7-compatible library ID and returns matching libraries.

You MUST call this function before 'query-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.

Selection Process:

1. Analyze the query to understand what library/package the user is looking for
2. Return the most relevant match based on:

• Name similarity to the query (exact matches prioritized)
• Description relevance to the query's intent
• Documentation coverage (prioritize libraries with higher Code Snippet counts)
• Source reputation (consider libraries with High or Medium reputation more authoritative)
• Benchmark Score: Quality indicator (100 is the highest score)

Response Format:

• Return the selected library ID in a clearly marked section
• Provide a brief explanation for why this library was chosen
• If multiple good matches exist, acknowledge this but proceed with the most relevant one
• If no good matches exist, clearly state this and suggest query refinements

For ambiguous queries, request clarification before proceeding with a best-guess match.

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 result you have. — $0.01/call

• 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.
