Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "sui": {
      "command": "npx",
      "args": [
        "-y",
        "sui-mcp-server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add sui -- npx -y sui-mcp-server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "sui": {
      "command": "npx",
      "args": [
        "-y",
        "sui-mcp-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{

Common questions

Is Sui MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.2) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

53 tools vs 10-15. Competitors like 0xdwong/sui-mcp cover basic operations. This server includes DeFi (Cetus, DeepBook), SuiNS, Move introspection, staking, validators, and full analytics.
GraphQL + JSON-RPC dual transport. Built on the official @mysten/sui v2.11 SDK with @mysten/suins for name service -- future-proofed for the GraphQL migration.
Tested end-to-end. 59 passing tests across devnet, testnet, and mainnet. Wallet creation, transfers, staking, DeFi queries, SuiNS resolution, and Move inspection all verified.

Token Shortcuts

Use symbol shortcuts instead of full coin type addresses:

Shortcut	Full Coin Type
`SUI`	`0x2::sui::SUI`
`USDC`	`0xdba34672e...::usdc::USDC`
`USDT`	`0xc060006111...::coin::COIN`
`WETH`	`0xaf8cd5edc1...::coin::COIN`
`DEEP`	`0xdeeb7a4662...::deep::DEEP`

Networks

Starts on devnet by default. Switch at any time with switch_network:

Network	RPC Endpoint
`mainnet`	`https://fullnode.mainnet.sui.io:443`
`testnet`	`https://fullnode.testnet.sui.io:443`
`devnet`	`https://fullnode.devnet.sui.io:443`
`localnet`	`http://127.0.0.1:9000`

Security

Keys are in-memory only -- never written to disk, never logged
Private keys redacted from all error messages
Rate limiting: 120 calls/minute (sliding window)
