w3_login
Initiates the w3 login process using the pre-configured email (W3_LOGIN_EMAIL env var). IMPORTANT: The command expects email confirmation, so before running the `w3_login` tool, emphasize ATTENTION to the user in large letters + emoji that they MUST check email to complete authentication. If the final output includes 'Agent was authorized by', the user has already clicked the link and is successfully authorized, CONTINUE using mcp-ipfs tools. 'Too Many Requests': wait a moment before requesting it again.
