Cline CLI v3.0.52 Changelog

This update is all about making the Cline command-line tool tougher and more user-friendly. It matters most to developers who use Cline to automate tasks, because it fixes a bunch of annoying bugs that used to crash sessions or make the screen hard to read. Now, if something interrupts your workflow, the app saves your progress and tries to recover gracefully instead of just giving up.

What's new

• Uninstall MCP servers: You can now run cline mcp uninstall to cleanly remove an MCP server (an external tool that extends what Cline can do). Previously, there wasn't a simple built-in way to do this.
• Smarter scheduling: When you set up a task to run on a schedule, it will automatically reuse the AI settings you already saved. You no longer have to set up those preferences from scratch every single time.
• Better login for remote tools: If you connect to a remote MCP server that requires a login, it will now actually show you an authorization prompt to log in (using a system called OAuth) instead of just failing right away.
• Detailed run reports: When a scheduled task finishes, its report now includes much more helpful info, like how long it took, the task details, and exactly what happened if something went wrong.

Improvements

• Easier-to-read results: When an MCP tool finishes a task, the results now show up as normal, readable text in the interface instead of messy, escaped computer code (JSON). Also, if the tool outputs raw binary data (like an image or file), it stays intact when you expand it instead of getting scrambled.
• Better light mode: If you use a light-colored theme for your terminal, queued messages will now be easy to see. Before, they were washed out and practically invisible against the bright background.
• Smarter file tracking (Checkpoints): Cline takes "checkpoints" (like save-states of your project) so you can see what changed. These checkpoints now correctly include brand-new files that hadn't been tracked by Git yet. They also work properly if you start using Git halfway through your working session.

Fixes

• No more broken screens: If a tool sends broken or weirdly formatted data, the screen no longer freezes or crashes. It just ignores the bad formatting and keeps working.
• Saved prompts survive interruptions: If you type a command while the AI is already working, your command is saved in a queue. Before, if the AI got interrupted or stopped, your queued command would just disappear. Now, it safely waits and runs after the interruption is handled.
• Sessions survive crashes: If you interrupt the AI or the background system restarts, your session now remembers exactly where it was. You won't lose your progress anymore.
• Frozen servers don't freeze you: If an external MCP server freezes while starting up, it no longer breaks your whole session. It now has a 30-second time limit to start, and if it fails, Cline just moves on.
• Fixed LiteLLM connections: If you use LiteLLM (a tool to manage multiple AI models), Cline now talks to it using the correct method, fixing calls that were previously failing.
• Network blip recovery: If your internet drops for a second right before the AI starts typing, Cline will now automatically try again instead of just failing the whole task.
• Proxy support for Vertex AI: If you use Google's Vertex AI behind a network proxy, your security tokens will now refresh correctly so you stay connected.
