resourceTemplate do not - but do actually work in Python SDK v1.2.0

[wanderingnature]

Describe the bug
resourceTemplates do not work, but actually it seems they do work....

To Reproduce
Steps to reproduce the behavior:
Follow the example at: https://github.com/modelcontextprotocol/python-sdk
Create the Demo server in latest release:

# server.py
from mcp.server.fastmcp import FastMCP

# Create an MCP server
mcp = FastMCP("Demo")

# Add an addition tool
@mcp.tool()
def add(a: int, b: int) -> int:
    """Add two numbers"""
    return a + b

# Add a dynamic greeting resource
@mcp.resource("greeting://{name}")
def get_greeting(name: str) -> str:
    """Get a personalized greeting"""
    return f"Hello, {name}!"

@mcp.resource("config://app")
def get_config() -> str:
    """Static configuration data"""
    return "App configuration here"

@mcp.resource("users://{user_id}/profile")
def get_user_profile(user_id: str) -> str:
    """Dynamic user data"""
    return f"Profile data for user {user_id}"

Expected behavior
Using inspector I should be able to 'List Resources' (that works) and 'List Templates(throws error).
Click List Templates in inspector throws:
Error
MCP error -32601: Method not found

I should see the two resourceTemplates in my Demo server.py
There are open issues in this repository related to same behavior with resourceTemplates and ./.venv/lib/python3.12/site-packages/mcp/server/fastmcp/server.py there is:

    def _setup_handlers(self) -> None:
        """Set up core MCP protocol handlers."""
        self._mcp_server.list_tools()(self.list_tools)
        self._mcp_server.call_tool()(self.call_tool)
        self._mcp_server.list_resources()(self.list_resources)
        self._mcp_server.read_resource()(self.read_resource)
        self._mcp_server.list_prompts()(self.list_prompts)
        self._mcp_server.get_prompt()(self.get_prompt)
        # TODO: This has not been added to MCP yet, see https://github.com/jlowin/fastmcp/issues/10
        # self._mcp_server.list_resource_templates()(self.list_resource_templates)

I removed the comment

    def _setup_handlers(self) -> None:
        """Set up core MCP protocol handlers."""
        self._mcp_server.list_tools()(self.list_tools)
        self._mcp_server.call_tool()(self.call_tool)
        self._mcp_server.list_resources()(self.list_resources)
        self._mcp_server.read_resource()(self.read_resource)
        self._mcp_server.list_prompts()(self.list_prompts)
        self._mcp_server.get_prompt()(self.get_prompt)
        # TODO: This has not been added to MCP yet, see https://github.com/jlowin/fastmcp/issues/10
        self._mcp_server.list_resource_templates()(self.list_resource_templates)

Apparently resourceTemplates are added to MCP (and I use them myself prior to FastMCP, just with python SDK)
Now I get the expected result.

REQUEST:

{"method":"resources/templates/list","params":{}}

RESPONSE:

{"resourceTemplates":[{"uriTemplate":"greeting://{name}","name":"get_greeting","description":"Get a personalized greeting"},{"uriTemplate":"users://{user_id}/profile","name":"get_user_profile","description":"Dynamic user data"}]}

Desktop (please complete the following information):
OS: Monterey 12.7.6
Browser Chrome

Additional context
just need to remove the '#' and enable the method it seems...

Nothing more than un-commenting the comment and everything seems to work. I will be able to make a pull request on Monday and provide that change along with a few changes/additions to examples/ which improve them and use the resource templates. I'm also adding a 'client.py' in the examples that tests the examples themselves.

[dsp-ant]

This is now fixed in #137. Thank you for reporting this issue!

What is the function of @mcp.resource, I also don't understand.

How do I get the update? I used "uv" and the mcp that it installed still has it commented out.
Do I need to change something in the pyproject.toml file (shown below)

[project]
name = "tom2server"
version = "0.1.0"
description = "Basic test of mcp inspector"
readme = "README.md"
requires-python = ">=3.10"
dependencies = [
    "httpx>=0.28.1",
    "mcp[cli]>=1.1.2",
]

[sheffler]

Running the same demo server code as @wanderingnature showed at the front of this issue.
I manually uncommented the line.
Template resource is working with Inspector. :-)
In Claude-Desktop the template resource is not showing up, but greeting:// and config:// resources do.

Is that the expected behavior that Claude Desktop can't handle templates yet?

[wanderingnature]

AFAIK resource templates DO NOT work in Claude. Also, there's another bit to fixing this for a client you develop - see #141
