# Pythonium

A modular Model Context Protocol (MCP) server designed to enable advanced capabilities for AI agents through a robust, extensible architecture built on the official MCP SDK.

## Overview

Pythonium provides a comprehensive, production-ready foundation for building sophisticated AI agent tools and capabilities. Built around the Model Context Protocol specification and leveraging the official MCP SDK (FastMCP), it offers a clean separation of concerns through its modular package structure and streamlined configuration management.

## Architecture

### Core Packages

- **`pythonium.common`** - Shared utilities, configuration management, and base components
- **`pythonium.core`** - Central server implementation, configuration, and tool management
- **`pythonium.tools`** - Comprehensive standard tool library with extensible framework
- **`pythonium.managers`** - Lightweight management systems for specialized functionality

## Features

### MCP SDK Integration
- Built on the official MCP SDK's FastMCP framework
- Full Model Context Protocol compliance
- Multiple transport support (stdio, HTTP, WebSocket)
- Native tool registration and capability negotiation

### Comprehensive Tool Library
- **System Operations**: Command execution, environment access, system monitoring (`pythonium.tools.std.execution`)
- **File Operations**: Advanced file and directory management (`pythonium.tools.std.file_ops`)
- **Web Operations**: HTTP client, web search with multiple engines (`pythonium.tools.std.web`)
- **Tool Management**: Meta-tools for tool discovery and introspection (`pythonium.tools.std.tool_ops`)

### Advanced Configuration
- Pydantic-based configuration with validation
- Environment variable integration
- Multiple format support (YAML, JSON, TOML)
- Hot-reload capability and override support

### Production Features
- Structured logging with multiple output formats
- Comprehensive error handling and recovery
- Resource management and connection pooling
- Security considerations and rate limiting
- Performance optimizations with async architecture

```

### Testing

The project uses pytest for testing with comprehensive coverage across all components:

- **Unit Tests**: Individual component testing 
- **Integration Tests**: Cross-component interaction testing  
- **Core Tests**: Configuration, server, and tool management
- **End-to-End Tests**: Full MCP server functionality
- **Performance Tests**: Load testing and benchmarks

**Current Status**: Comprehensive test coverage across all modules ensuring reliability and maintainability.

```bash
# Run all tests
pytest

# Run with coverage reporting
pytest --cov=pythonium --cov-report=html

# Run specific test categories
pytest tests/core/         # Core functionality tests
pytest tests/tools/        # Tool implementation tests
pytest tests/common/       # Common utilities tests

# Quick test run
pytest -q

# Verbose test output
pytest -v
```

## Configuration

Pythonium uses Pydantic-based configuration with support for multiple formats (YAML, JSON, TOML) and environment variable integration:

```yaml
# config/server.yaml
server:
  name: "Pythonium MCP Server"
  description: "A modular MCP server for AI agents"
  host: "localhost"
  port: 8080
  transport: "stdio"  # stdio, http, websocket

tools:
  # Tool discovery and loading configuration
  auto_discover: true
  categories:
    - "system"
    - "web"
    - "file_operations"

logging:
  level: "INFO"           # DEBUG, INFO, WARNING, ERROR
  format: "structured"    # structured, plain
  output: "console"       # console, file

security:
  authentication: "none"  # none, api_key
  rate_limit:
    enabled: false
    requests_per_minute: 60
```

## Tool Development

### Creating a Custom Tool

```python
from pythonium.tools.base import BaseTool, ToolMetadata, ToolParameter, ParameterType
from pythonium.common.base import Result
from pythonium.common.parameters import validate_parameters

class MyCustomTool(BaseTool):
    """A custom tool example with proper parameter validation."""
    
    @property
    def metadata(self) -> ToolMetadata:
        return ToolMetadata(
            name="my_custom_tool",
            description="A custom tool example that demonstrates the framework",
            brief_description="Custom tool example",
            category="custom",
            tags=["example", "custom"],
            parameters=[
                ToolParameter(
                    name="message",
                    type=ParameterType.STRING,
                    description="Message to process",
                    required=True,
                    min_length=1,
                    max_length=1000
                )
            ]
        )
    
    @validate_parameters  # Automatic parameter validation
    async def execute(self, message: str, context: ToolContext) -> Result:
        """Execute the tool with validated parameters."""
        try:
            result = f"Processed: {message}"
            return Result.success_result(
                data={"result": result, "original": message},
                metadata={"tool": "my_custom_tool"}
            )
        except Exception as e:
            return Result.error_result(f"Tool execution failed: {e}")
```

### Tool Registration

Tools are automatically discovered and registered when placed in the appropriate package structure. The tool discovery system handles:

- Automatic tool detection and registration
- Parameter validation and schema generation
- Error handling and logging
- Integration with the MCP protocol
