A VSCode exte- preview_url: Open URLs within VSCode's integrated browser
generate_commit_message: Generate conventional commit messages based on Git changession that turns your VSCode into an MCP server, enabling advanced coding assistance from MCP clients like Claude Desktop.
Key Features
Code Editing Support
Review proposed code changes from an LLM through diffs, allowing you to accept, reject, or provide feedback.
Real-time diagnostic messages (e.g., type errors) sent instantly to the LLM for immediate corrections.
Terminal Operations
Execute commands within VSCode’s integrated terminal (supports background/foreground execution, and timeout settings).
Preview Tools
Preview URLs directly within VSCode’s built-in browser (e.g., automatically opens browser preview after starting a Vite server).
Multi-instance Switching
Easily switch the MCP server between multiple open VSCode windows.
Relay Functionality (Experimental)
Relay and expose built-in MCP servers introduced in VSCode 1.99 externally.
Allows external access to tools provided by other MCP extensions, such as GitHub Copilot.
Available Built-in Tools
execute_command: Execute commands in VSCode’s integrated terminal
code_checker: Retrieve current diagnostics for your code
focus_editor: Focus specific locations within files
Check the MCP server status in the bottom-right VSCode status bar:
✅: Server is running
∅: Click to start the server
Motivation
This extension was developed to mitigate high costs associated with metered coding tools (like Roo Code and Cursor). It's an affordable, self-hosted alternative built directly into VSCode.
Bug reports and feedback are very welcome! 🙇
Future Roadmap
Ability to select which built-in MCP servers to expose
WebView-based approval UI (similar to Roo Code)
Integration with VSCode's file history (Timeline)
Instant toggling of auto-approvals and tool activation/deactivation
