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

`USDT`	`0xc060006111...::coin::COIN`
`WETH`	`0xaf8cd5edc1...::coin::COIN`
`DEEP`	`0xdeeb7a4662...::deep::DEEP`

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`
