Anthropic recently unveiled a new feature for its terminal tool, Claude Code, allowing developers to manage terminal sessions remotely via mobile devices or web browsers. This innovation promises to enhance flexibility and improve task management efficiency.
Overview of the Remote Control Feature
Currently available in a Research Preview for Max users, the ‘Remote Control’ feature introduces significant versatility in handling terminal tasks. However, it is essential to consider the technical architecture and security implications accompanying this new capability.
The feature, announced through the official Claude account on X, aims to facilitate seamless transitions between devices, enabling continuous task management irrespective of location.
Technical Specifications and Activation
To activate the Remote Control feature, users can run claude rc or claude remote-control in their terminal environment. Additionally, users can set it as a default by configuring the /config command, thus allowing remote control for all sessions.
- Network Exposure: Strictly outbound HTTPS with no open inbound ports
- Encryption: Encrypted with TLS and short-lived tokens to mitigate hijacking risks
- Concurrency: Limited to one active session to avoid command conflicts
- Timeout: Automatic termination after a 10-minute disconnect
Security and Implementation Details
The security model for Claude Code’s Remote Control feature is designed to minimize potential vulnerabilities. It initiates outbound HTTPS requests and does not open any inbound ports, thereby limiting network exposure.
When a user connects through a mobile client, communications are securely streamed via encrypted channels. This setup employs short-lived, single-purpose credentials to prevent token theft or unauthorized session access.
Despite these precautions, it is crucial to understand the distinction between Claude’s execution modes to ensure effective threat modeling. Local repository cleanliness remains paramount due to potential vulnerabilities inherent in extending terminal control to mobile devices.
Before the release, a security flaw identified as CVE-2025-59536 exposed risks related to Remote Code Execution and API token exfiltration. Anthropic addressed these issues by implementing user consent requirements, emphasizing the importance of maintaining secure project configuration files.
