mcp-context7

Call resolve-library-id with the library name and your query, then call query-docs with the resolved ID and a specific topic. Always resolve the ID first rather than guessing, and include version and topic details in your query.

Context7 is an MCP server that provides live, version-specific documentation for libraries and frameworks. It lets coding agents query official docs at runtime instead of relying on potentially outdated training data.

Retry with broader search terms, then fall back to WebSearch for official documentation. If the server times out or is down, use cached session results or built-in knowledge while noting the limitations.

Limit lookups to a maximum of three calls per question and use the best result after three attempts. Specific queries with version and topic details reduce the number of calls needed.

Skip it for general reasoning, code review, or business logic tasks that do not depend on current library APIs. It is intended specifically for verifying external dependency documentation and framework patterns.
