McpServerly exhibits significant definition quality gaps. Tool names lack consistent verb-noun structure (GetClients vs SendReportWithMarkdown). Descriptions are present but generic and lack actionable context for LLM selection. Parameter descriptions are minimal or absent. No input schemas are visible in the provided code, tool definitions appear to rely on C# reflection via [McpServerTool] attributes rather than explicit JSON Schema registration. Output schemas are undocumented. Error handling is minimal (boolean returns, generic exceptions). The server uses STDIO transport, which is not remotely accessible and caps protocol readiness at 50.

• Standardize tool names to lowercase snake_case with clear verb-noun structure: 'get_clients', 'send_report_markdown', 'send_report_html', 'generate_report'. Ensure each name reflects a single action.
• Split compound tools: 'SendReportWithMarkdown' and 'SendReportWithHtml' both convert and send. Create separate 'convert_markdown_to_html' and 'send_report_email' tools so agents can compose them independently.
• Add explicit JSON Schema registration for all tool inputs. Document parameter types (string, number, boolean), constraints (min/max length, enums, regex patterns), and descriptions (50-100 chars each). Ensure schemas are visible to MCP clients.
• Document output schemas for all tools. For GetClients, specify the Client object structure (id, email, firstName, lastName, address fields, createdAt format). For send tools, return structured {success: boolean, message_id: string, error?: string} instead of bare boolean.
• Implement structured error responses. Replace boolean returns with {success: boolean, error?: {code: string, message: string, recovery_hint: string}}. Classify errors as retryable (network timeout) vs user-fixable (invalid email) vs fatal (permission denied).
