This MCP server has critical definition quality issues. The tools provided ('get_weather' and 'get_current_time') appear 8 times in the tool list with exact duplicates, suggesting either a data collection error or severe artifact organization problems. More importantly, the source code provided is NOT an MCP server implementation, it is a JavaScript test script (anthropic-toolcall-no-stream.js) that demonstrates Anthropic API calls, not MCP server code. The pyproject.toml indicates the actual server is Python-based but no Python MCP implementation is visible in the provided source. Tool definitions exist with proper JSON schemas and basic descriptions, but lack the depth, error guidance, and parameter documentation expected of production-grade tools. Descriptions are minimal (50-80 chars) and lack 'when to use this' context. Parameter descriptions are present but generic. No error handling guidance is documented. No output schema documentation is provided.

• Provide the actual Python MCP server implementation. The source code must be the real server, not a test harness for Anthropic's API.
• Remove duplicate tool definitions from the manifest. Each tool should appear exactly once.
• Expand tool descriptions to 150-300 characters. Include: (1) what the tool does, (2) when to use it instead of alternatives, (3) what it returns, (4) error handling hints. Example: 'Get current weather for a location. Returns temperature, condition, humidity, wind speed. Timezone-aware. If location is ambiguous (e.g. Springfield), the tool picks the most populous match; ask user to clarify if needed.'
• Document the output schema explicitly. For get_weather, specify: {temperature: number, unit: string, condition: string, humidity: number (0-100), wind_speed: number}. For get_current_time, specify: {time: ISO-8601 string, timezone: string, unix_timestamp: number}.
• Add parameter constraints: location should accept 'City, Country' format; timezone should accept IANA timezone identifiers or '+/-HH:MM' offsets.
• Specify a default for unit (recommend 'celsius') and document it in the description.
• Add error guidance to descriptions: 'If location is not recognized, returns null with a suggestion for similar locations. If timezone is invalid, returns an error listing valid timezones near the provided string.'
• Implement and document idempotency: both tools are READ_ONLY and idempotent, so the descriptions should state 'Safe to retry on network failure, results do not change between calls.'
