Aptos Claude Agent

Aptos blockchain interaction with game-theoretic decision analysis.

When to Use

• Check APT wallet balances
• Transfer APT tokens
• Swap tokens on DEX (Liquidswap, etc.)
• Stake APT
• Call Move view functions
• Process natural language blockchain intents
• Query NFT/token collections
• Interact with multisig accounts

Setup

MCP server configured in ~/.mcp.json:

{
  "aptos": {
    "command": "node",
    "args": ["/path/to/aptos-claude-agent/dist/mcp/server.js"],
    "env": {
      "APTOS_NETWORK": "mainnet",
      "APTOS_PRIVATE_KEY": "${APTOS_PRIVATE_KEY}"
    }
  }
}

Available MCP Tools

Tool	Description
aptos_balance	Get wallet balance
aptos_transfer	Transfer APT (requires approval)
aptos_swap	Swap tokens on DEX (requires approval)
aptos_stake	Stake APT (requires approval)
aptos_view	Read-only view function call
aptos_intent	Process natural language intent
aptos_approve	Approve/reject pending decision
aptos_pending	List pending decisions

Security Model

1. Simulation First: All transactions simulated before execution
2. Approval Required: Every state-changing operation needs explicit approval
3. Game-Theoretic Analysis: Transactions modeled as open games
4. Wallet Validation: ALWAYS validate key→address before funding

CRITICAL: Wallet Derivation Safety

NEVER use derive-resource-account-address for wallet creation.

Correct Workflow

# 1. Generate key
aptos key generate --output-file my_key

# 2. Derive address FROM PRIVATE KEY
aptos init --private-key-file my_key --network mainnet --profile my_wallet

# 3. VALIDATE before funding
just aptos-validate "PRIVATE_KEY" "EXPECTED_ADDRESS"

# 4. Only fund AFTER validation passes

What Can Go Wrong

• Using derive-resource-account-address with pubkey = PERMANENT FUND LOSS
• Resource accounts need signer capabilities from source account
• If key doesn't match address, funds are unrecoverable

Validation

Run just aptos-validate-all to verify all configured wallets before any funding operation.

Common View Function Patterns

Check APT Balance

aptos_view(
  functionId: "0x1::coin::balance",
  typeArgs: ["0x1::aptos_coin::AptosCoin"],
  args: ["0xADDRESS"]
)

Check Token Balance (Legacy)

aptos_view(
  functionId: "0x3::token::balance_of",
  typeArgs: [],
  args: ["0xOWNER", { token_data_id: {...}, property_version: 0 }]
)

Check Stake

aptos_view(
  functionId: "0x1::stake::get_stake",
  typeArgs: [],
  args: ["0xVALIDATOR_POOL"]
)

Check Delegation

aptos_view(
  functionId: "0x1::delegation_pool::get_stake",
  typeArgs: [],
  args: ["0xPOOL", "0xDELEGATOR"]
)
