Single tool with minimal definition quality. Tool name 'wikipedia_mcp_tool' lacks action verb (should be 'search_wikipedia' or 'get_wikipedia_article'). Description is present but generic and exceeds 1024 chars (violates baseline). Input schema exists with 'topic' parameter but lacks proper type constraints, enums, or format guidance. No output schema documented. Error handling returns unstructured dicts without recovery guidance. Tool is read-only but lacks explicit readOnlyHint annotation. No pagination, no result limits documented despite Wikipedia API returning variable-length summaries.

• Rename tool to 'search_wikipedia' (verb_noun pattern). Update description to: 'Search Wikipedia for an article by title or topic. Returns article summary (max 500 chars), title, and URL. Use when user asks about people, places, events, or concepts.'
• Add explicit output schema: {"type": "object", "properties": {"found": {"type": "boolean"}, "title": {"type": "string"}, "summary": {"type": "string", "maxLength": 500}, "url": {"type": "string", "format": "uri"}}}
• Constrain 'topic' parameter: add maxLength: 200, pattern: '^[a-zA-Z0-9\s\-]+$', and description: 'Wikipedia article title or search term (1-200 chars, letters/numbers/spaces/hyphens only).'
• Improve error messages: return structured errors like {"found": false, "error": "Article not found for 'xyz'. Try: search_wikipedia with a more specific term or check spelling.", "suggestions": ["Try a broader topic", "Check spelling"]}
• Add readOnlyHint: true annotation to tool definition to signal to LLM that this tool is safe to call without confirmation.

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
