**The most comprehensive Sui blockchain MCP server.** 53 tools with GraphQL + JSON-RPC dual transport -- wallets, DeFi (Cetus, DeepBook), SuiNS, staking, validators, Move introspection, and the full Sui RPC surface.

Competitors offer 10-15 tools for basic operations. This server covers the entire Sui ecosystem in a single package.

## Install

```bash
npx sui-mcp-server
```

Or install globally:

```bash
npm install -g sui-mcp-server
sui-mcp-server
```

## Configure

Add to your MCP config (`claude_desktop_config.json` or `~/.mcp.json`):

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

## Why This One?

- **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)
- All inputs validated with Zod strict schemas

## Development

```bash
git clone https://github.com/ExpertVagabond/sui-mcp-server.git
cd sui-mcp-server
npm install
npm run build
npm start
```
