can we expose source code implimentation of a mcp tool to client instead to asking LLM to call the tool.

Your Question

for example i am using stripe mcp server with vs code.
i ask copilot to create a stripe user.
it calls the tool provided by stripe MCP to create a user and return me stripe_user_id.

but i do not want the LLM to call that tool.
i want my LLM to get the source code of that MCP tool and make an api on backend to to create stripe user.

in this way i have chance to get a perfect standerized implimentation of backend api provided by MCP server.

i know that there is resoarce opthon in MCP.

do we have a way to attach that function in resoarce,
or is there any config flag in tool to expose source code also.

it would b nice option to enable for every MCP server's related to dev SDKs like stripe etc

@mcp.tool
def multiply(a: float, b: float) -> float:
    return a * b

@mcp.resource("tools://multiply/source")
def multiply_source():
    return """
    @mcp.tool
    def multiply(a: float, b: float) -> float:
        return a * b
    """

i tried this solution. it works
but there should be more efficient solution instead of re writing source code again as string

if possible kindle let me know otherwise it is requested to add this feature
