Just two steps to quickly build an easily extensible mcp server framework that supports all Model Context Protocol (MCP) transmission modes (STDIO, SSE, Streamable Http).
Please give a like, friends!
Define the configuration information needed for your project in src/config/.env, for example, if you need 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
Add your own tool class in the src/handles directory, refer to the example.py sample
- Inherit from BaseHandler
- Define the
nameproperty, which is the name of the tool - Define the
descriptionproperty, which is the description of the tool - Implement the
get_tool_descriptionmethod, which tells the mcp client what your tool does - Implement the
run_toolmethod, which is the method called by the mcp client to use the tool; implement your tool logic here - Import 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",
]
Currently, this framework supports all Model Context Protocol (MCP) transmission modes (STDIO, SSE, Streamable Http).
- Use uv to start the service
Add the following content to your mcp client tool, such as cursor, cline, etc.
mcp json example:
{
"mcpServers": {
"easyMcp": {
"name": "easyMcp",
"type": "streamableHttp",
"description": "",
"isActive": true,
"baseUrl": "http://localhost:3000/mcp/"
}
}
}
Start command
# Install dependencies
uv sync
# Start
uv run src/server.py
- Use uv to start the service
Add the following content to your mcp client tool, such as cursor, cline, etc.
mcp json example:
{
"mcpServers": {
"easyMcp": {
"name": "easyMcp",
"description": "",
"isActive": true,
"baseUrl": "http://localhost:9000/sse"
}
}
}
Start command
# Install dependencies
uv sync
# Start
uv run src/server.py --sse
Add the following content to your mcp client tool, such as cursor, cline, etc.
mcp json example:
{
"mcpServers": {
"operateMysql": {
"isActive": true,
"name": "operateMysql",
"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"
}
}
}
}
