SecureMCP is critically underdeveloped as an MCP server. The codebase shows only one tool ('scan') with a minimal schema and no meaningful parameter descriptions. The tool definition exists in the HTTP handler (internal/server/server.go:handleScan) but lacks proper MCP tool registration semantics. The 'scan' tool accepts only a 'target' string parameter with no validation, range, format guidance, or examples. The description 'Scan an MCP server for vulnerabilities' is generic and does not explain when to use it, what vulnerabilities it detects, or what the output structure is. The implementation is incomplete, both handleScan and handleGetReports contain TODO comments indicating core logic is not implemented. There is no evidence of an MCP-compliant tool registry, no output schema documentation, no error handling guidance, and no indication this implements the current MCP spec (2026-07-28). The server uses a custom HTTP/Gin-based setup without demonstrable MCP protocol compliance.

• Implement proper MCP tool registration with explicit inputSchema. Define 'target' parameter as a JSON Schema object with type (string), description ('MCP server endpoint or hostname to scan, e.g., localhost:8080 or https://mcp.example.com'), minLength (1), maxLength (255), and pattern (optional regex for URL validation).
• Document the output schema. Define what the scan tool returns: { success: boolean, vulnerabilities: [{type: string, severity: 'critical'|'high'|'medium'|'low', description: string, remediation: string}], scanDuration: number, scanTime: string (ISO 8601) }.
• Expand the tool description to 50-200 characters. Example: 'Scan an MCP server for common security vulnerabilities including authentication bypass, unvalidated input, and missing rate limiting. Returns a list of discovered issues with severity and remediation steps. Scan typically completes in 30-120 seconds.'
• Add parameter description for 'target'. Example: 'The MCP server endpoint to scan. Can be a hostname (localhost, example.com), IP address (192.168.1.1), or full URL (https://mcp.example.com:8080). Required.'
• Implement actual scan logic in handleScan() instead of the TODO placeholder. Until core functionality is implemented, the tool is non-functional.
• Add error classification and recovery guidance. When scan fails, return: { success: false, error: 'Connection timeout', retryable: true, suggestion: 'The target server did not respond. Verify the endpoint is running and accessible.' }
• Implement timeout handling. Add a ScanTimeout config parameter (default 30s) and return a structured timeout error if scanning exceeds the limit.
