What is the MCP Server?

The MCP server is an extensible server implemented based on the model context protocol, allowing new features to be added through a plugin system. It provides a powerful modular architecture that supports logging, client communication, and dynamic plugin loading.

How to use the MCP Server?

Users can configure the server through command-line parameters and run plugins to implement specific functions. The MCP server is easy to install and configure, making it suitable for developers and technical personnel.

Applicable Scenarios

The MCP server is suitable for application scenarios that require dynamic function expansion, such as weather forecasting, code review, and sleep simulation.

Main Features

Server CoreResponsible for initializing and managing all major functions of the server, including communication, logging, and plugin management.

Plugin SystemSupports dynamic plugin loading, allowing users to extend server functions without modifying the core code.

Logging ModuleCentralized logging for easy debugging and monitoring of server activities.

Command-Line InterfaceConfigure the server through command-line parameters, such as specifying the name, plugin directory, and log directory.

Advantages and Limitations

Advantages

Modular design for easy expansion.

Supports cross-platform (Windows, Linux, MacOS).

Dynamic plugin loading without restarting the server.

Rich logging functions for easy troubleshooting.

Limitations

Some advanced features (such as sampling) are still under development.

Limited support for resource templates.

Relies on external plugins to implement specific functions.

How to Use

Clone the code repository

First, clone the MCP server code to your local machine.

Compile the code

Enter the project directory and compile the server.

Configure the server

Set the server name, plugin directory, and log directory through command-line parameters.

Usage Examples

🚀 Quick Start

Core Components

Resource Manager: Responsible for loading and managing resources for the Model Context Protocol.
Hint System: Provides context - related hint functions.
Toolkit: Contains various auxiliary tools for plugin development and debugging.

Execution Flow

Initialize the server and configure parameters.
Load necessary resources and plugins.
Listen for client connections and handle requests.
Perform operations of the context protocol as needed.
Generate results and return them to the client.

Plugin Extensibility

The MCP server supports function extension through plugins. Plugins can add new resources, hint types, and tools, thereby enhancing the server's capabilities.

💻 Usage Examples

Plugin Examples

Weather Plugin: Integrates with a weather API to query weather information.
Sleep Plugin: Implements an interface with a sleep monitoring service to analyze user sleep data.
Code Review Plugin: Integrates a code review tool to provide real - time code checking.

Claude Desktop Configuration

Here is an example configuration file:

{
  "mcp-server": {
    "command": "C:\\mcp-server\\mcp_server.exe",
    "args": [
      "-n", "developer-server",
      "-l", "C:\\mcp-server\\logs",
      "-p", "C:\\mcp-server\\plugins"
    ],
    "env": {
      "CUSTOM_API_KEY_1": "your-api-key-here",
      "CUSTOM_API_KEY_2": "your-api-key-here",
      "SAVE_DIR": "/path/to/save/directory"
    }
  }
}

⚠️ Important Note

In the "env" block, you can pass parameters to your plugins.

To - Do List

Sampling [In progress]
Review the implementation of log levels.
Add a JSON schema validator (https://github.com/pboettch/json-schema-validator).
Implement SSE transmission.
Test on different MCP - clients (currently only tested on Claude Desktop).
