This server has critical definition gaps. Both tools lack meaningful descriptions (identical generic text: 'Get the total of books for children'), parameter descriptions are absent, and output schemas are undocumented. Tool names are verb-prefixed (get_*) but descriptions do not explain WHEN to use each tool or what distinguishes them. The first tool (get_books) accepts no parameters, yet its purpose is unclear, does it return all books, a count, or a filtered list? The second tool (get_books_by_title) accepts a 'title' parameter with a description, but the tool description itself is identical to the first, creating ambiguity. No output schema is visible in the source, and error handling is absent. This server would not pass code review for production use.

• Rewrite tool descriptions to be distinct and actionable. Example: get_books → 'Retrieve all available children's books. Returns a paginated list with title, author, ISBN, and availability status. Use this to browse the full catalog.' get_books_by_title → 'Search for children's books by exact or partial title match. Returns matching books with metadata. Use this when the user specifies a title.'
• Document the output schema for each tool. Specify fields (title, author, isbn, availability, book_id), types (string, boolean, integer), and whether results are paginated. Include a sample response.
• Add a limit parameter to get_books with a default of 20 and max of 100. Document pagination support (offset/limit or cursor) to prevent context window exhaustion.
• Add error handling guidance: 'If no books match the title, the tool returns an empty list. Suggest the user try a partial title or browse all books with get_books.'
• Expose the actual tool registration code (McpServerConfig or Spring AI annotations) in the source to verify schema completeness. Currently, tool definitions are opaque.
