Critical gaps across all dimensions. Tool definitions are inferred from example wrappers (TypeScript/JavaScript files in examples/) rather than visible in the Rust gateway codebase. No explicit tool registration, schemas, or descriptions found in the actual MCP server implementation (crates/gateway, crates/threat-engine). The threat-engine crate references 'tool_call.rs' but the actual tool definitions are not visible in provided source. Tool descriptions are generic placeholders ('protected by Proxilion') with no actionable guidance. Input schemas are minimal (only parameter names and types, no constraints, enums, or validation rules). No output schemas documented. Error handling is absent from visible code. This server appears to be a security gateway wrapper around tools rather than a fully-specified MCP server with proper tool definitions.

• Add explicit tool registration in gateway crate with full JSON Schema definitions. Move tool definitions from example wrappers into the core server implementation.
• Expand all descriptions to 50-200 characters. Example: 'read_file: Read and return the complete contents of a file at the specified path. Returns file content as a string. Use to inspect configuration, source code, or data files.'
• Add parameter constraints: bash/run_terminal_command should document timeout, max output size, and allowed command patterns. read_file/write_file should specify max file size and path validation rules.
• Document output schemas for each tool. Example: read_file returns {"content": string, "size_bytes": number, "encoding": string}. list_directory returns {"entries": [{"name": string, "type": "file"|"directory", "size_bytes": number}], "total_count": number}.
• Add error handling guidance: 'If command times out after 30s, the operation is retryable. If path is not found, use list_directory to discover available paths. If permission denied, verify user has read/write access.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
