Chat MCP

An example of a framework that leverages MCP(Model Context Protocol) to interface with other LLMs.

This example has been tested exclusively on Windows, but Electron itself is cross-platform.

The goal is to provide the SIMPLEST possible code to help you understand the principles of MCP.

Demo

Architecture

erDiagram
    Renderer ||--o{ APP : IPC
    APP ||--|{ Client : contains
    Client }|..|{ Server : Stdio

Loading

Only 3 key files: main.ts, client.ts, preload.ts

How to use

1. npm install

2. npm start

Configuration

Create a .json file and paste the following content into it. This file can then be provided as the interface configuration for the Chat UI.

• gtp-api.json

  {
      "chatbotStore": {
          "apiKey": "",
          "url": "https://api.aiql.com",
          "path": "/v1/chat/completions",
          "model": "gpt-4o-mini",
          "max_tokens_value": "",
          "mcp": true
      },
      "defaultChoiceStore": {
          "model": [
              "gpt-4o-mini",
              "gpt-4o",
              "gpt-4",
              "gpt-4-turbo"
          ]
      }
  }

You can replace the 'url' if you have direct access to the OpenAI API.

Alternatively, you can also use another API endpoint that supports function calls:

• qwen-api.json

  {
      "chatbotStore": {
          "apiKey": "",
          "url": "https://dashscope.aliyuncs.com/compatible-mode",
          "path": "/v1/chat/completions",
          "model": "qwen-turbo",
          "max_tokens_value": "",
          "mcp": true
      },
      "defaultChoiceStore": {
          "model": [
              "qwen-turbo",
              "qwen-plus",
              "qwen-max"
          ]
      }
  }

Troubleshooting

Error: spawn npx ENOENT - ISSUE 40

Modify the config.json in src/

On windows, npx may not work, please refer my workaround: ISSUE 101

• Or you can use node in config.json:

  {
      "mcpServers": {
          "filesystem": {
          "command": "node",
          "args": [
              "node_modules/@modelcontextprotocol/server-filesystem/dist/index.js",
              "D:/Github/mcp-test"
          ]
          }
      }
  }

Please ensure that the provided path is valid, especially if you are using a relative path. It is highly recommended to provide an absolute path for better clarity and accuracy.

By default, I will install server-everything, server-filesystem, and server-puppeteer for test purposes. However, you can install additional server libraries or use npx to utilize other server libraries as needed.
