Five tools with clear verb-noun naming and documented schemas. Tool descriptions are present (avg 120 chars) but lack depth on WHEN to use each tool and dependencies between them. Parameters are typed with enums where appropriate (e.g., category, client), but descriptions are sparse (avg 45 chars). Output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal; no recovery guidance. add_to_stack accepts env vars but lacks validation rules or secret injection guidance. Overall: functional definitions with moderate gaps in LLM-optimization and error guidance.

• Document output schemas for all tools. E.g., search_servers returns {servers: [{slug, name, category, description, url}], total, hasMore}. This enables LLMs to chain tools (e.g., extract slug from search result, pass to get_server_details).
• Expand parameter descriptions to 60 - 100 chars with format/constraint hints. E.g., 'query: Search term (2 - 50 chars, e.g. "GitHub", "database"). Supports partial matches.' and 'limit: Max results (1 - 50, default 10)'.
• Add error recovery guidance in tool descriptions. E.g., 'If no results, try list_categories to explore available categories, then search again with a category filter.'
• For add_to_stack, document required env vars per server. Replace additionalProperties=true with explicit schema: {type: object, properties: {API_KEY: {type: string, description: 'Required. Set via environment, not as parameter.'}}, required: ['API_KEY']}. Add note: 'Env vars are injected server-side; never pass secrets as parameters.'
• Add tool annotations (readOnlyHint, destructiveHint) to clarify side effects. search_servers, get_server_details, install_server, list_categories are read-only. add_to_stack is destructive (modifies stack config).
