Server has 4 tools with clear action verbs and reasonable descriptions (100-200 chars each). All tools have input schemas with typed parameters and descriptions. However, output schemas are not formally documented, tools return JSON strings rather than structured objects with declared fields. Parameter descriptions lack constraint details (ranges, enums, formats). Error handling is minimal; tools do not guide recovery or categorize errors. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all tools being read-only. Missing dependency hints and multi-step guidance.

• Add formal output schema declarations to tool metadata. Document that search_mcp_servers returns {query: string, results: [{name, version, description, package_identifier, transport_type, has_remote, sources[], use_count, verified, rank}], next_actions: string[]}. Use JSON Schema or OpenAPI format.
• Convert parameter constraints to enum types in schema. Replace transport_type: string with transport_type: enum[stdio, streamable-http, sse, any]. Declare platform as enum[claude-desktop, cursor, claude-code, cline, windsurf] in get_install_config.
• Add readOnlyHint: true annotation to all 4 tools. This signals to agents that these tools are safe to call without confirmation and do not modify state.
• Enhance error handling. When get_server_details(name='xyz') fails, return: {error: 'Server not found', suggestion: 'Try search_mcp_servers(query="xyz") to find the correct name', retryable: false}. Categorize errors as retryable, user_fixable, or fatal.
• Add dependency hints to descriptions. E.g., get_server_details: 'Call search_mcp_servers first if you only have a partial name or keyword.' This guides multi-step planning and reduces wasted calls.
