[BUG] Prompt

[pierre-sigwalt]

Describe the bug I have followed the document for prompting and getting the error when trying to get the prompt using the mcp client (ALso using MCP Inspector)

To Reproduce

• prompt.py:

from fastmcp import FastMCP

template_mcp = FastMCP(name="Template")

@template_mcp.prompt()
def generate_content_request() -> str:
    """Create a request for generating content in a specific format."""
    prompt = f"Please write a "
    return prompt

• server.py

import os

from fastmcp import FastMCP

from templates import template_mcp

mcp = FastMCP("Lj Template MCP")
mcp.mount(
    prefix="template",
    server=template_mcp
)

http_app = mcp.http_app(
    transport="streamable-http"
)

• client.py

from fastmcp import Client
from fastmcp.client.transports import SSETransport

sse_transport = SSETransport(url=sse_url)
# transport_explicit = StreamableHttpTransport(url=http_url)

mcp_client = Client(sse_transport)

system_prompts = await mcp_client.get_prompt("template_generate_content_request")

Am I missing something?

Thank you for the help!
