easyMcp

Just two steps to help developers quickly build an extensible mcp server framework that supports both stdio and SSE startup modes.

User Manual

1. Step One [Optional] Define Required Configuration

Define your project's required configuration in src/config/.env, for example, database configuration:

 # MySQL Database Configuration
MYSQL_HOST=192.168.3.229
MYSQL_PORT=3306
MYSQL_USER=root
MYSQL_PASSWORD=root
MYSQL_DATABASE=a_llm
MYSQL_ROLE=admin

2. Step Two Create Your Own Tools

Add your own tool classes in the src/handles directory, refer to the example.py sample

• Inherit from BaseHandler
• Define the name property, which is the tool's name
• Define the description property, which is the tool's description
• Implement the get_tool_description method, which tells the mcp client what your tool does
• Implement the run_tool method, which is called by the mcp client to execute your tool's logic
• Reference the new tool in init.py

example.py

from typing import Dict, Any, Sequence

from mcp import Tool
from mcp.types import TextContent
from .base import BaseHandler
from config import get_config


class Example(BaseHandler):
    name = "get_Example"
    description = (
        "this is Example xxxx"
    )

    def get_tool_description(self) -> Tool:
        return Tool(
            name=self.name,
            description=self.description,
            inputSchema={
                "type": "object",
                "properties": {
                    "text": {
                        "type": "string",
                        "description": "This is the text that must be entered for the example"
                    }
                },
                "required": ["text"]
            }
        )

    async def run_tool(self, arguments: Dict[str, Any]) -> Sequence[TextContent]:

            try:
                if "text" not in arguments:
                    raise ValueError("Missing text content")

                text = arguments["text"]

                # Reference configuration information
                config = get_config()

                ## todo something

                result = "xxxxxxx"

                # Join all results with commas
                return [TextContent(type="text", text=','.join(result))]

            except Exception as e:
                return [TextContent(type="text", text=f"error: {str(e)}")]

init.py

from .example import Example


__all__ = [
    "Example",
]

3. Startup

Currently, this framework supports two startup modes: stdio and SSE.

1. SSE Mode

• Start the service using uv

Add the following content to your mcp client tool, such as cursor, cline, etc.

mcp json as follows

{
  "mcpServers": {
    "easyMcp": {
      "name": "easyMcp",
      "description": "",
      "isActive": true,
      "baseUrl": "http://localhost:9000/sse"
    }
  }
}

Startup command

# Download dependencies
uv sync

# Start
uv run server.py

2. STDIO Mode

Add the following content to your mcp client tool, such as cursor, cline, etc.

mcp json as follows

{
  "mcpServers": {
      "easyMcp": {
        "isActive": true,
        "name": "easyMcp",
        "command": "uv",
        "args": [
          "--directory",
          "G:\\python\\mysql_mcp\\src",  # Replace this with your project path
          "run",
          "server.py",
          "--stdio"
        ],
        "env": {
          "MYSQL_HOST": "192.168.xxx.xxx",
          "MYSQL_PORT": "3306",
          "MYSQL_USER": "root",
          "MYSQL_PASSWORD": "root",
          "MYSQL_DATABASE": "a_llm",
          "MYSQL_ROLE": "admin"
       }
    }
  }
}
