  The handler function for the 'get_user_info' tool, registered with @mcp.tool(). It fetches user data from the Dev.to API and formats the profile, handling not-found errors.
  @mcp.tool() async def get_user_info(username: str) -> str: """ Get information about a Dev.to user Args: username: The username of the user """ try: user = await fetch_from_api(f"/users/{username}") return format_user_profile(user) except httpx.HTTPStatusError as e: if e.response.status_code == 404: return f"User {username} not found." raise e
