Quickstart: Cursor

Cursor can read, write, and manage files on OpenTusk through MCP tools — vaults, files, folders, encryption, and sharing — all accessible through natural language in the Cursor chat.

Note

Need to install the CLI first? See Install & Setup.

Setup

1. Install the MCP config

   opentusk mcp install-config --target cursor

   This writes the MCP server configuration to ~/.cursor/mcp.json with absolute paths to the opentusk binary.

2. Restart Cursor

   Restart Cursor or reload the window. The OpenTusk tools should appear in Cursor’s tool list.

3. Try it out

   Open the Cursor chat and try:

   “List my OpenTusk vaults”

Shared vault access

To enable SEAL encryption for shared vaults, add your Sui private key:

opentusk account setup-sui suiprivkey1...
opentusk mcp install-config --target cursor  # re-install to embed the key

Troubleshooting

Symptom	Fix
Tools not appearing	Restart Cursor — it reads ~/.cursor/mcp.json at startup
”Command not found”	Re-run opentusk mcp install-config --target cursor for absolute paths
”Invalid API key”	Verify with opentusk whoami
