Single tool 'search_web' has a well-structured schema with proper type definitions, min/max constraints, and defaults. Description is clear and includes appropriate safety warnings (unverified results, not suitable for critical decisions). Parameter descriptions are present and specific. However, output schema is not documented in the visible code, the tool returns results but the structure of those results is not formally specified. Error handling is present but generic. Tool naming follows verb_noun convention correctly. Overall solid for a single-tool server, but lacks output schema documentation and richer error guidance.

• Document the output schema explicitly: specify that results are an array of objects with fields like 'title', 'url', 'snippet', and their types. Include example output structure in comments.
• Enhance error messages with recovery guidance: 'Rate limit exceeded (10 searches/min). Wait 30 seconds before retrying.' or 'Parsing timeout: search provider response too complex. Try a more specific query.'
• Add rate-limit information to tool description: 'Limited to 10 searches per minute, 60 per hour. Exceeding limits returns an error.'
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport to enable remote deployment and hosted client compatibility.
• Add tool annotations (readOnlyHint=true) to signal to clients that this tool is safe and has no side effects.
