The server exposes 2 tools with partial but incomplete quality. Tool names follow verb-noun convention (internet_search, think_tool), which is correct. Descriptions exist and are reasonably detailed for both tools, placing them above average (194 chars baseline). However, schema completeness is uneven: internet_search has full parameter schemas with enums and defaults, but think_tool's schema is minimal. Neither tool documents output schemas explicitly, which is a significant gap for LLM planning. The think_tool is a reasonable internal reasoning pattern, but its documentation as a public tool is questionable. Error handling and security practices are not visible in the provided code. The server integrates with Tavily Search (a remote MCP client), suggesting it functions as a Streamlit frontend rather than a standalone MCP server, which raises transport and architecture questions.

• Add explicit output schema documentation for internet_search. Example: 'Returns {results: [{title: string, url: string, snippet: string, raw_content?: string}], search_depth: string}'. This lets LLMs know which fields to extract.
• Document think_tool's return value schema. Currently it returns the input thought unchanged, make this explicit: {thought: string} output, not just the docstring.
• Add error handling guidance to internet_search description: 'If the search fails due to rate limits, the tool returns an error. Retry after 30 seconds. If API key is invalid, notify the user.'
• Implement pagination for internet_search results. Current implementation has max_results default of 5, but add explicit limit and offset/cursor support in schema if the underlying Tavily API supports it.
• Reconsider exposing think_tool as a public MCP tool. If it's purely for agent internal reasoning, move it into the agent planning layer rather than as a callable tool. If it remains public, document when/why an LLM should call it vs. just reasoning inline.
• Add parameter descriptions clarifying expected input format for query: 'A natural language search query. Examples: "climate change impact 2024", "stock market trends". Avoid special operators unless Tavily syntax is documented.'
• Document the topic enum's behavior. What distinguishes 'general' from 'news'? Does 'finance' return only stock/crypto data? This helps LLMs choose the right category.
• Add constraint documentation for max_results parameter: 'Integer from 1 to 100. Higher values increase latency and token cost. Default 5 is recommended for most queries.'
