This collection of 15 tools shows inconsistent quality. While all tools have basic descriptions and input parameters visible in code, several critical issues reduce quality significantly: (1) Schema completeness varies, most tools show parameter type hints in Python signatures but lack formal JSON Schema documentation; (2) Descriptions are often generic and under-specified (e.g., 'List files in the given path up to specified depth' lacks context on when to use this vs alternatives, typical return size, or use cases); (3) No evidence of error handling guidance, tools like load_url, load_sitemap, and search offer no guidance on what errors are retryable or how to recover; (4) Parameters lack important constraints, voice tool accepts enum values but time/file tools have unvalidated string parameters; (5) STDIO transport is a hard ceiling of 50. The codebase appears functional and tools are reasonably named (verb-first: list_files, read_file, search, etc.), but production readiness is limited by transport choice and schema formality.

• Document formal JSON Schema for all tools. Use fastmcp/mcp decorators to emit explicit 'properties', 'type', 'description', and 'required' fields per tool parameter. Ensure schemas are registered and visible in the MCP server capabilities.
• Expand all tool descriptions to 100-200 characters minimum, including: (1) what it does, (2) when to use it vs similar tools, (3) typical return format (list of strings, dict, paginated results), (4) common prerequisites or setup required.
• Add error handling guidance to every tool description. Example: 'Returns an error if the path does not exist or lacks read permissions. This is retryable if permissions are being granted. Call list_files() first to discover valid paths.' Follow the recovery-guide pattern.
• Constrain string parameters with enums or regex patterns. For timezone parameters, either: (a) call time_timezone_list() to populate the enum at startup, or (b) include a comment like 'IANA timezone string (e.g., America/New_York, UTC, Europe/London). Call time_timezone_list() to see all valid values.' in the description.
• Document return types and structures in tool descriptions. Example: 'Returns a list of file paths (strings), one per line. Each path is relative to the root folder. Does not include file metadata, call get_file_info(path) for size, permissions, or timestamps.'
• Migrate from STDIO to Streamable HTTP (SSE or WebSocket). STDIO servers cannot be remotely accessed by hosted MCP clients. Implement a simple HTTP server with /sse endpoint for bidirectional MCP protocol.

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