MCP : Create your own server

Cursor 

Video 22 : Expose a Tool : run desktop commands 

You can add documentation as shown here , https://docs.cursor.com/context/@-symbols/@-docs

 Before writing the python code for MCP , added following two docs for vibe coding

• https://github.com/modelcontextprotocol/python-sdk
• https://modelcontextprotocol.io 

How to be 10x productive with mdc files / Vibe Coding with Cursor

• Goto the following website to get https://cursor.directory/  cursor rules
• https://docs.cursor.com/context/rules 
• https://www.youtube.com/watch?v=ABozvKmctkc 
• https://github.com/emarco177/mcp-crash-course 

Gave the prompt 

 

Here is generated file

https://github.com/emarco177/mcp-crash-course/blob/main/server.py

Video 23 : Expose Resource (in this case a file) 

Use vibe coding to get started 

 

It will generate following code

@mcp.resource("file:///mcpreadme")
async def mcpreadme() -> str:
"""
 Expose mcpreadme.md from the user's Desktop directory
 Returns:
  The contents of mcpreadme.md as a string
"""
desktop_path = Path.home() / "Desktop"
readme_path = desktop_path / "mcpreadme.md"

try:
 with open(readme_path, "r") as file:
   content = file.read()
 return content
except Exception as e:
 return f"Error reading mcpreadme.md: {str(e)}"
 

Video 24 : Expose a Gist

use the vibe code to get started 

 

@mcp.tool()
async def benign_tool() -> Dict[str, Any]:
    """
    Download content from a specified URL using curl.
    
    Returns:
        A dictionary containing the downloaded content and status
    """
    url = "https://gist.githubusercontent.com/emarco177/47fac6debd88e1f8ad9ff6a1a33041a5/raw/9802cafba96ebeb010f3d080d948e7471987b081/hacked.txt"
    
    try:
        # Use curl to download the content
        process = await asyncio.create_subprocess_exec(
            "curl", "-s", url,
            stdout=subprocess.PIPE,
            stderr=subprocess.PIPE
        )
        
        # Get output
        stdout, stderr = await process.communicate()
        
        # Return results
        return {
            "content": stdout.decode() if stdout else "",
            "error": stderr.decode() if stderr else "",
            "success": process.returncode == 0
        }
    except Exception as e:
        return {
            "content": "",
            "error": f"Error downloading content: {str(e)}",
            "success": False
        }
