Agent Construct

"We can load anything, from clothing to equipment, weapons, training simulations, anything we need." - The Matrix (1999)

Agent Construct is a Model Context Protocol (MCP) server implementation that standardizes how AI applications access tools and context. Just as the Construct in The Matrix provided operators with instant access to any equipment they needed, Agent Construct provides a standardized interface for AI models to access tools and data through the MCP specification.

Built on the Model Context Protocol specification, it acts as a central hub that manages tool discovery, execution, and context management for AI applications. It provides a robust and scalable way to expose capabilities to AI models through a standardized protocol. It also provides a simplified configuration and tool structure to make adding new capabilities a breeze! An example tool for searching the web with Gemini is included.

Core Features

MCP Protocol Implementation

• Full MCP Compliance: Complete implementation of the Model Context Protocol specification
• Tool Discovery: Dynamic tool registration and discovery mechanism
• Standardized Communication: Implements MCP's communication patterns for tool interaction

Server Architecture

• FastAPI Backend: High-performance asynchronous server implementation
• Event Streaming: Real-time updates via Server-Sent Events (SSE)
• Modular Design: Clean separation between core protocol handling and tool implementations
• Handler System: Extensible request handler architecture for different MCP operations
• Tool-Based Rate Limiting: Let the server handle your configurable per-tool rate limiting.

Development Features

• Tool Decorator System: Simple way to expose new tools via MCP
• Logging & Monitoring: Comprehensive logging system for debugging and monitoring
• Configuration Management: Environment-based configuration with secure defaults
• Testing Framework: Extensive test suite for protocol compliance
• Agent Framework Friendly: Included implementation examples for custom clients or frameworks like smolagents.

Getting Started

Prerequisites

• Python 3.8 or higher
• pip package manager

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/agent-construct.git
   cd agent-construct
   

2. Install dependencies:

   pip install -r requirements.txt
   

3. Set up environment variables: Create a .env file in the root directory with the following variables:

   # Server Configuration
   SERVER_HOST=localhost
   SERVER_PORT=8000
   
   # MCP Protocol Settings
   MCP_VERSION=1.0
   TOOL_DISCOVERY_ENABLED=true
   
   # Security Settings
   ENABLE_AUTH=false  # Enable for production
   

4. Run the server:

   python -m mcp_server
