Single tool 'get_uk_weather' has a reasonable description (127 chars, within 10-1024 range) and a properly typed input schema with location parameter. However, the schema lacks descriptions for the 'location' parameter itself (only has type:string), violating the requirement that every parameter needs a description explaining what it controls. No output schema is documented, LLMs cannot plan downstream calls or extract structured data. The tool name follows verb_noun convention (get_uk_weather), which is good. Risk classification (READ_ONLY) is present but tool lacks error handling guidance, recovery paths, or examples of valid inputs (e.g., postcode format). No pagination, no rate-limit guidance, no structured output schema. Overall, the tool is minimally viable but falls short of production quality.

• Add a complete output schema documenting all response fields (e.g., temperature, wind_speed, condition, advice). Example: {type: 'object', properties: {location: {type: 'string'}, temperature_c: {type: 'number'}, wind_mph: {type: 'number'}, condition: {type: 'string'}, advice: {type: 'string'}}}
• Add description to the 'location' parameter: 'UK city name or postcode (e.g., London, Manchester, SW1A 1AA, M1 1AE). Postcodes must be valid UK format.'
• Add error handling guidance to tool description: 'Returns error if location is not found or API is unavailable. If location fails, suggest user try a nearby city or postcode.'
• Migrate from STDIO to HTTP+SSE or Streamable HTTP transport to enable remote accessibility and hosted client compatibility.
• Add tool annotations to the tool definition: include readOnlyHint: true to signal to LLMs that this tool is safe to call without confirmation.
