Summary
Devin Desktop 3.4.22, released July 4, 2026, updates the local Devin agent (formerly Windsurf's Cascade) so it uses the files a developer has open as context, adds server-level MCP tool permissions (approve every tool on a server for the session or permanently), makes 'Always Allow' grants persist across sessions, and runs plan mode inside the OS sandbox.
What changed
Devin Desktop 3.4.22 made Devin Local aware of currently open editor files as context, added two server-level MCP permission options (approve all tools on a server for the session or permanently), persisted 'Always Allow' grants across sessions, improved plan mode to run in the OS sandbox, and raised the remote-server startup timeout to 6s.
Why it matters
Editor-context awareness and coarser server-level MCP consent reduce prompting friction and make a local coding agent feel less like a separate tool, while persistent Always-Allow and sandboxed plan mode trade some per-tool safety prompting for smoother long-running autonomy. It also marks the post-rebrand direction after Windsurf became Devin Desktop under Cognition.
Evidence excerpt
Devin Local is now aware of the files you have open in the editor as part of its context; MCP tool permission prompts now offer server-level 'approve all tools on the server for the session or permanently'; 'Always Allow' grants persist across sessions (Devin Desktop 3.4.22, July 4, 2026).
