required
Absolute path to the workspace directory exposed through VS Code and MCP tools.
MCP_VSCODE_RENDER_MODE
Set to 'stream' to opt into experimental genuine-workbench pixel streaming; omit for normal iframe/browser behavior.
MCP_VSCODE_STREAM_BROWSER

MCP_VSCODE_STREAM_NO_SANDBOX
Unsafe container-only escape hatch: set to 1 to launch streaming Chromium without its process sandbox.
