Cline ​

Cline is an autonomous coding agent that runs inside VS Code with a distinctive human-in-the-loop philosophy. Every action — file edit, terminal command, MCP tool call — is presented for your approval before execution. You see the exact diff, the exact command, the exact tool call parameters. Approve, reject, or modify. This makes Cline the safest agent for production codebases where you need full visibility into every change.

Approval-First Agent with Transparent MCP Calls ​

Cline's approval workflow extends to MCP tool calls. Before any MCP tool is invoked, you see exactly what parameters the agent is sending. This transparency is critical when MCP tools interact with production systems — you control what data goes in and what comes out.

The agent handles multi-step tasks: read files, analyze code, write changes, run tests, call MCP tools for external data, and iterate. Each step pauses for approval unless you opt into auto-approval for specific action types.

Browser automation is built in. Cline can launch a browser, navigate to URLs, take screenshots, and interact with web pages — useful for testing web applications or scraping data during development.

Features:

  • Human-in-the-loop — every action shown for approval before execution
  • Diff previews — see exact code changes before they're applied
  • First-class MCP — dedicated MCP panel for server management
  • Browser automation — navigate, screenshot, and interact with web pages
  • Multi-model — Claude, GPT, Gemini, Ollama, any OpenAI-compatible API
  • Cost tracking — real-time token usage and API cost display
  • Auto-approval — optionally skip approval for specific action types
  • Open-source — Apache 2.0 license

Setup in VS Code ​

1. Create a Token ​

In Vinkius Cloud, go to your server → Connection Tokens → Create. Copy the URL.

2. Add MCP Server ​

In the Cline panel → MCP Servers tab → Add → paste your Vinkius URL.

3. Approve and Execute ​

When the agent calls an MCP tool, you see the parameters and can approve, reject, or modify before it executes.

FAQ ​

Can I skip the approval step for MCP tool calls? Yes. Enable auto-approval for specific action types if you trust the MCP server.

Does Cline show what data is sent to MCP tools? Yes. Every MCP tool call shows the exact parameters before execution.

Does Cline support browser automation? Yes. The agent can launch browsers, navigate, take screenshots, and interact with web pages.
