No tools, no resources listed in MCP Servers in Cline

[davideuler]

I created the echo mcp server as documented by FastMCP like this :

from fastmcp import FastMCP

mcp = FastMCP("Echo")

@mcp.resource("echo://{message}")
def echo_resource(message: str) -> str:
    """Echo a message as a resource"""
    return f"Resource echo: {message}"

@mcp.tool()
def echo_tool(message: str) -> str:
    """Echo a message as a tool"""
    return f"Tool echo: {message}"

@mcp.prompt()
def echo_prompt(message: str) -> str:
    """Create an echo prompt"""
    return f"Please process this message: {message}"


if __name__ == "__main__":
    # Initialize and run the server
    mcp.run(transport='stdio')

And configured it in the Cline configurations as:

    "echo": {
      "type": "stdio",
      "command": "uv",
      "args": [
            "--directory",
            "/Users/david/workspace/agent/oss",
            "run",
            "echo.py"
        ]
    }

On the MCP Server list of Cline, there isn't any tools listed(However the tools works in conversation). The message shows:

[01/14/25 11:26:56] INFO Processing request of type server.py:432 ListToolsRequest INFO Processing request of type server.py:432 ListResourcesRequest INFO Processing request of type server.py:432 ListResourceTemplatesRequest

For official File and Sqlite MCP Server, there is tools and resources listed. How could I make the tool listed in the MCP Servers?
