mcp-farmer is a scaffolding/analysis CLI tool, not a production MCP server itself. The only visible tool definition is 'hello' in src/new/templates/src/server.ts, which is a template example, not a real tool. The 'hello' tool has minimal description (19 chars: 'Says hello to the provided name'), a single parameter 'name' with basic schema, and no documented output schema. The tool lacks detail on return format, error handling, and proper context for LLM selection. As a template generator, mcp-farmer provides scaffolding but the example tool definition falls well short of production quality. The codebase includes vetting logic (src/vet/tools.ts) that checks for description quality (minimum 50 chars), missing input descriptions, dangerous/PII keywords, and similar tools, but this is analysis code, not evidence of the scaffolded servers meeting those standards.

• Expand 'hello' tool description from 19 to 50 - 150 chars: 'Greet a user by name and return a personalized greeting message. Useful for acknowledgments, confirmations, and friendly interactions. Accepts any non-empty string.'
• Document the return schema explicitly: { type: 'object', properties: { greeting: { type: 'string', description: 'Formatted greeting message' }, timestamp: { type: 'string', format: 'date-time' } } }
• Rename tool from 'hello' to 'greet_user' to match verb_noun convention and clarify action intent
• Add parameter constraints to 'name': min length 1, max length 100, pattern to reject special characters if applicable
• Document error cases: 'Returns error if name is empty, null, or exceeds 100 characters. LLM should prompt user for a valid name and retry.'
• Add field-level descriptions: name parameter should specify 'The person's first name or display name (1 - 100 characters, alphanumeric and spaces only)'
