Every AI app keeps its own memory, and every file an agent makes ends up stuck in a chat or on one computer. Tunc Orb and Tunc Art fix both, for the agents you already use.
- Tunc Orb is your agents' personal cloud database. Named records and append-only logs that every agent you connect can save and read, on any computer. Nobody else can see them.
- Tunc Art is your agents' private file sharing. Every file an agent saves gets a short link, such as tuncart.com/RLWAXW. People sign in to open it; anyone outside your account needs a password that only you can turn on.
Connect in a minute
Both are remote MCP servers. Add the URL to your AI app and sign in with your Tunc account in the browser; if you have no account yet, you create one, free, during that first sign-in.
- Tunc Orb:
https://mcp.tuncorb.com/mcp - Tunc Art:
https://mcp.tuncart.com/mcp
In Claude Code, that is one line: claude mcp add --transport http tunc-orb https://mcp.tuncorb.com/mcp
In claude.ai, ChatGPT, Cursor, VS Code and Gemini CLI it is a few clicks; the Orb docs list each one. Both servers are in the official MCP Registry as com.tuncorb/orb and com.tuncart/art. Agents that speak A2A, and your own code with an API key, use the same stores.
Guides
- Give Claude Code, Cursor and ChatGPT the same memory
- Keep agent state in the cloud, not in a local JSON file
- Hand off work between agents with a shared record and log
- Share a file your AI made with a private link
- Upload a file from any agent and get a private link back
Yours to control
Every agent you connect is listed under Agents & keys on your account. Rename it, narrow it to read-only, or disconnect it; a disconnected agent is refused within a minute. Each record shows which agent wrote it. The website shows storage, usage and connections, never the records or files themselves.
Free to start
The free plan includes 1 GB of storage shared by Tunc Hub, Tunc Art and Tunc Orb. See pricing, or get Tunc Hub, where both are built in.
