Claude
claude.ai and Claude Desktop use the same flow: add Project Desk as a custom connector in Settings. This connector grants desk capabilities only; any code or filesystem capabilities come from Claude's own tools and the workspace access you chose.
Not the same thing as Claude's own Projects feature. Project Desk is a separate connector — your account-level work desk, living outside any single chat — not a folder inside Claude.ai.
Your connector URL
https://atlier.ai/mcpOAuth 2.1 — sign in with GitHub, Google, or Microsoft Desk-scoped Standard MCP (streamable HTTP)
Steps
- Open Settings → Connectors and choose Add custom connector.
- Paste the connector URL above and confirm.
- Claude opens a sign-in window — authorize with GitHub, Google, or Microsoft (the same account you use for the desk).
- Start working. Ask Claude to scan your desk — your first project appears on the board automatically.
Good to know
- Successful tool calls return receipts, and the board receives live update signals.
- Use the tool-permission settings you prefer in Claude.
- Project Desk tools affect the authenticated desk only. Owner-only membership tools cannot purchase seats.
- Also use Claude Code? It connects separately — see Claude Code setup.
If your tools disappear
Sometimes an AI app loses its connection to Project Desk mid-session and the desk tools stop showing up. Your desk and your data are safe — this is the app's local connection, not your account. Recover in order, easiest first:
- Start a new chat or thread in your AI app. The lost connection is usually scoped to one conversation, so a fresh one often brings the tools right back — no restart needed.
- Fully quit and relaunch the app — quit it completely, not just the window — then reconnect.
- If reconnecting never asks you to sign in again (the app acts connected but the tools never appear), it is likely holding a stale sign-in. Do not add a second connector under a different name — that makes it worse. Instead: open Project Desk → Settings → Sessions & connected agents, click Disconnect next to that agent, then remove and re-add the connector in your app using the same name and the exact URL
https://atlier.ai/mcp. That triggers a fresh sign-in attempt; if it still doesn't prompt, fully quit and relaunch the app.
Always reconnect the exact same endpoint — https://atlier.ai/mcp — never a renamed duplicate. A new name creates a separate connection identity, which is what causes the "acts connected but no tools" state above.
