FAQ from Sui Serverless MCP

What is the difference between zkLogin and Private Key modes?

In zkLogin mode, the private key is never exposed and write operations require manual approval via the dashboard. In Private Key mode, operations execute automatically but the user must securely manage the private key.

How do I obtain an access key for zkLogin mode?

The access key can be obtained from the Sui Serverless MCP dashboard. After logging in, a unique access key is generated for each user.

What tools are available in Sui Serverless MCP?

The server provides over 10 tools including sui_get_wallet_address, sui_get_all_balances, sui_transfer_token, sui_stake, sui_get_stake, sui_unstake, sui_deploy_token, sui_get_sns_name_record, sui_register_sns, sui_get_swap_quote, and sui_swap_tokens.

Can I run Sui Serverless MCP on Linux with NVM?

Yes, but you must manually configure the absolute path to Node.js and the installed module, as NVM installs libraries in version-specific directories.

Does Sui Serverless MCP require external servers for transaction processing?

In Private Key mode, transactions are handled locally without exposing data to external servers. In zkLogin mode, transaction requests are pushed to a backend and stored pending approval, requiring the dashboard for write operations.
