Folder is the API, MCP, and terminal-first filesystem for durable agent context, application uploads, and shared workspaces.
Remote filesystem
Folder is agent-native from the ground up. Your agent reads, writes, and shares files through REST, MCP, the CLI, or SDK. Start from one command and stay in your existing workflow. When a human needs to inspect activity, manage keys, or browse files, the dashboard and optional Mac bridge provide clear controls without becoming the center of the product.
Here's what that actually looks like.
Claude Code, Codex, Cursor, LangChain, CrewAI, or your own custom setup. One install, one backup, one terminal session.

Works inside any terminal session. Claude Code, Codex, Cursor, LangChain — if it runs in a shell, it works with Folder.
folder for mac
Local sync for macOS with guided setup, Folder Sync logs, Finder actions, and a real preview DMG download.
folder.md/dash
Browse, search, and manage everything from folder.md/dash. See what every agent is doing in real time.

Any agent — local, remote, or on another device — can read and write via REST API or MCP protocol.
New native layer
There is now a proper desktop preview surface on folder.md. It is honest about the current state: testable today, delivered as a real preview DMG, and still clearly marked as an unsigned developer preview.
Every Folder and subfolder gets a folder.md file automatically. It defines what the directory is for, how to name things, who has access, and what the rules are. Your agents read it, follow it, and never deviate. They can edit it too — if they have permission. It's where the product gets its name.
Folder is usable today through scoped API keys, REST, MCP, the CLI, SDK helpers, activity history, and the dashboard. The current preview is for testing real agent and app-storage workflows while limits, reliability targets, and commercial plans are measured and hardened.
Developer preview
Create scoped keys, connect through API or MCP, install F-stack, and validate Folder against a real agent or app workflow. Published pricing will follow measured storage, request, egress, reliability, and support costs.
Available in the preview
Preview limits and behavior may change as the service is hardened. Do not assume enterprise compliance or production-scale media guarantees.
Multi-agent, cross-platform.
Your research agent finds papers. Your writing agent drafts the report. Your deploy agent ships it — Claude Code, LangChain, CrewAI, your own scripts. They all read and write to the same Folders across any framework. No hand-offs, no copy-paste, no lost context.
One scoped storage layer for context, artifacts, and application files.
Agent-first cloud storage.
API and MCP-ready from day one.
