[Python] MCP Python SDK. How to authorise a client with Bearer header with SSE?

I am building the MCP server application to connect some services to LLM . I use the MCP Python SDK https://github.com/modelcontextprotocol/python-sdk One of things i want to implement is authorisation of a user with the token.



I see it must be possible somehow.

Most of tutorials about MCP are related to STDIO kind of a server run. My will be SSE.

There is my code:

from mcp.server.fastmcp import FastMCP
from fastapi import FastAPI, Request, Depends, HTTPException

app = FastAPI()
mcp = FastMCP("SMB Share Server")

@mcp.tool()
def create_folder(parent_path: str, name: str) -> str:
"""Create new subfolder in the specified path"""
return f"Folder {name} created in {parent_path}"

app.mount("/", mcp.sse_app())


How can i read Authorization header in case if it is sent by the client?

I tried to use approaches of FastAPI - setting dependency, adding request:Request to arguments but this doesn't work.

Is there a way?
