Overview

This package provides a Python interface to connect to MCP servers in an easy, intuitive, and configurable way. It offers a modular architecture that allows for easy extension of new transfer protocols and language models. Currently includes support for HTTPStream and GPT-4 mini, with expansion capability for more options in the future.

Installation

To install the MCP client, you can use pip:

pip install mcp-llm-client

Implemented Models

The client currently supports the following language models:

Model	Technical Description
gpt4o-mini	Optimized implementation of the GPT-4 model that provides a balance between computational performance and resource efficiency. This model is specifically designed to operate in environments with memory constraints while maintaining superior predictive quality.

Implemented Transfer Protocols

Protocols for communication with MCP servers:

Protocol	Status	Technical Characteristics
HTTPStream	Implemented	Asynchronous HTTP-based protocol that enables continuous data streaming. Characterized by low memory consumption and real-time processing capability for partial responses.
SSE (Server-Sent Events)	Not Implemented	Unidirectional protocol that allows the server to send multiple updated events through a single HTTP connection. Designed specifically for applications requiring real-time updates from the server.
stdio	Not Implemented	Standard input/output interface that facilitates direct communication between processes. Will provide a lightweight alternative for local environments and unit testing.

Future Development Planning

Pending Language Models

• Integration of additional language models
• Implementation of dynamic model selection system
• Optimization of model loading and management

Pending Protocols

• Complete implementation of SSE for better real-time event handling
• Development of stdio interface for local environments
• Performance optimization across all protocols

System Requirements

Environmental Configuration

• .env file: The .env file contains the authentication credentials necessary for integration with external services. This file must be created in the project root directory with the following format:

  # .env
  # OpenAI Authentication
  OPENAI_API_KEY=<YOUR OPENAI-API-KEY>
  

• config.json file: The config.json file defines the configuration of available MCP servers. It must be created in the project root directory with the following structure:

  {
      "mcp_servers": {
          "example_server": {
              "http": "http://0.0.0.0:8000/server/mcp",
              "name": "Example mcp server",
              "description": "A simple example MCP server"
          }
      }
  }
  

  If you need an MCP server to test the code, you can use simple-mcp-server.

Software Requirements

• Python 3.11+
• openai package
• fastmcp package

Usage Example

#main.py
from mcpclient import ClientLLM

#Create a client
client: ClientLLM = ClientLLM()

while True:
    query:str = input("> ")
    #call client with a string query
    print(client(query))

Version History

v0.0.1

• Initial implementation of ClientLLM client
• Complete integration of httpstream protocol (fasmcp)
• Connectivity with multiple servers
• Simplified config.json file for connection management
• Efficient processing of multiple simultaneous requests to tools and resources within a single query
• Simple connection without authorization (compatible only with servers that do not require authentication)
