ToolUniverse Architecture

This document provides a technical overview of ToolUniverse’s architecture, helping you understand how the system works internally.

System Overview

ToolUniverse is built around a modular, registry-based architecture that supports both local and remote tools through a unified interface.

Core Components:

Key Design Principles: - Modularity: Tools are independent modules - Extensibility: Easy to add new tool types - Unified Interface: Same API for local and remote tools - Lazy Loading: Tools loaded on demand - Error Isolation: Tool failures don’t crash the system

Tool Registry System

Local Tool Registry The local tool registry manages Python-based tools that run within the ToolUniverse process.

Registration Process: 1. Tool class decorated with @register_tool 2. Tool metadata stored in registry 3. Tool available for discovery and execution

Key Classes: - ToolRegistry: Manages tool registration and discovery - BaseTool: Base class for all local tools - ToolMetadata: Stores tool configuration and metadata

Remote Tool Registry The remote tool registry manages external tools accessed via MCP or REST APIs.

Registration Process: 1. Tool configuration loaded from JSON files 2. MCP client connections established 3. Tool capabilities discovered and registered

Key Classes: - MCPToolRegistry: Manages MCP tool connections - RemoteTool: Wrapper for remote tool execution - MCPClientTool: Handles MCP protocol communication

Tool Execution Engine

Execution Flow: 1. Request Parsing: Parse tool name and arguments 2. Tool Discovery: Find tool in registry 3. Parameter Validation: Validate arguments against schema 4. Tool Execution: Execute tool (local or remote) 5. Result Processing: Format and return results 6. Error Handling: Handle and report errors

Key Components: - ToolExecutor: Main execution engine - ParameterValidator: Validates tool parameters - ResultProcessor: Formats tool results - ErrorHandler: Manages error reporting

Execution Modes: - Synchronous: Blocking execution for immediate results - Asynchronous: Non-blocking execution for long-running tasks - Batch: Execute multiple tools in sequence

Configuration System

Configuration Hierarchy: 1. Default Configuration: Built-in tool configurations 2. User Configuration: User-provided configurations 3. Runtime Configuration: Dynamic configuration updates

Configuration Sources: - JSON files in data/ directory - Environment variables - Command-line arguments - Runtime API calls

Configuration Validation: - JSON Schema validation - Type checking - Required field validation - Dependency resolution

Key Classes: - ConfigManager: Manages configuration loading and validation - ToolConfig: Represents individual tool configuration - ConfigValidator: Validates configuration schemas

MCP Integration

MCP (Model Context Protocol) MCP provides a standardized way to integrate external tools and services.

MCP Components: - MCP Server: External service providing tools - MCP Client: ToolUniverse component connecting to servers - MCP Protocol: Communication protocol between client and server

MCP Features: - Tool Discovery: Automatic discovery of available tools - Parameter Validation: Server-side parameter validation - Error Handling: Standardized error reporting - Authentication: Secure communication protocols

Key Classes: - MCPClient: Handles MCP protocol communication - MCPServer: Base class for MCP servers - MCPTool: Represents MCP-based tools

MCP Communication Flow: 1. Connection: Establish connection to MCP server 2. Discovery: Query available tools and capabilities 3. Registration: Register tools in local registry 4. Execution: Execute tools via MCP protocol 5. Result Handling: Process and return results

Error Handling and Logging

Error Types: - Validation Errors: Parameter validation failures - Execution Errors: Tool execution failures - Network Errors: Remote tool connection failures - System Errors: Internal system failures

Error Handling Strategy: - Graceful Degradation: System continues with partial failures - Error Isolation: Tool failures don’t affect other tools - Detailed Logging: Comprehensive error logging and reporting - User-Friendly Messages: Clear error messages for users

Logging System: - Structured Logging: JSON-formatted log entries - Log Levels: DEBUG, INFO, WARNING, ERROR, CRITICAL - Log Rotation: Automatic log file rotation - Remote Logging: Optional remote log aggregation

Key Classes: - ErrorHandler: Centralized error handling - Logger: Logging system - ErrorReporter: Error reporting and notification

Performance and Scalability

Performance Optimizations: - Lazy Loading: Tools loaded on demand - Caching: Result caching for expensive operations - Connection Pooling: Reuse connections for remote tools - Async Execution: Non-blocking tool execution

Scalability Features: - Horizontal Scaling: Multiple ToolUniverse instances - Load Balancing: Distribute load across instances - Resource Management: Monitor and limit resource usage - Auto-scaling: Automatic scaling based on load

Monitoring: - Performance Metrics: Execution time, memory usage - Health Checks: System and tool health monitoring - Alerting: Automated alerting for failures - Dashboards: Real-time monitoring dashboards

Key Classes: - PerformanceMonitor: Tracks performance metrics - ResourceManager: Manages system resources - HealthChecker: Monitors system health

Security Considerations

Security Features: - Input Validation: Strict parameter validation - Authentication: Secure authentication for remote tools - Authorization: Role-based access control - Encryption: Encrypted communication for sensitive data

Security Best Practices: - Principle of Least Privilege: Minimal required permissions - Secure Defaults: Secure configuration by default - Regular Updates: Keep dependencies updated - Security Auditing: Regular security audits

Key Classes: - SecurityManager: Manages security policies - Authenticator: Handles authentication - Authorizer: Manages authorization

Testing Framework

Testing Strategy: - Unit Tests: Test individual components - Integration Tests: Test component interactions - End-to-End Tests: Test complete workflows - Performance Tests: Test system performance

Testing Tools: - pytest: Primary testing framework - Mocking: Mock external dependencies - Fixtures: Reusable test components - Coverage: Code coverage reporting

Key Classes: - TestRunner: Executes test suites - TestFixtures: Provides test data and setup - MockTool: Mock tool for testing

Development Guidelines

Code Organization: - Modular Design: Clear separation of concerns - Interface Segregation: Small, focused interfaces - Dependency Injection: Loose coupling between components - Configuration Management: Centralized configuration

Code Quality: - Type Hints: Complete type annotations - Documentation: Comprehensive docstrings - Code Formatting: Consistent code style - Linting: Automated code quality checks

Key Classes: - CodeFormatter: Ensures consistent code style - Linter: Performs code quality checks - DocumentationGenerator: Generates documentation
