Security Findings (14)

  • LowAS-002

    ⚠️Excessive Permissions

    search_books:input schema exposes 12 properties (threshold: 10)

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    search_booksget_author_photoget_book_cover

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.
