Tower MCP — Claude Connector
Tower Exchange supports Anthropic's Model Context Protocol (MCP), allowing you to connect Claude directly to Tower's decentralized exchange aggregator on Arc.
Once connected, you can interact with your Web3 wallet and Tower's smart routing engine directly in your conversational Claude chat sessions:
- Query Wallet Balances: Ask Claude to check your live EURC, USDC, and other token holdings.
- Get Smart Swap Quotes: Compare DEX rates and discover optimal routes across Arc liquidity pools.
- Execute Swaps In-Chat: Authorize and execute swaps with a single confirmation.
- Non-Custodial Security: You retain full control over your funds. Claude only requests signed execution with your explicit permission.

Step 9: One-time unlock & connection confirmation

After the transaction confirms on Arc, the window will show Signed in. Returning to Claude....
Return to Claude. You will see a green checkmark next to Tower Exchange and a confirmation toast: "Connected to Tower Exchange."
Step 10: Query your wallet balance
Open a new or existing chat in Claude and ask:
"What's my wallet balance?"
Claude uses the Tower Exchange · get_wallet_balances MCP tool to fetch your live on-chain balances (EURC, USDC) and total portfolio value.
Step 11: Execute swaps & grant permissions
To execute a token swap directly inside Claude, send a prompt such as:
"Swap 5 EURC to USDC"
Claude queries Tower Exchange · get_swap_quote for the optimal DEX route on Arc, and then prompts you for permission:
"Allow Claude to use swap from Tower Exchange?"
Then wait for few minutes Claude will ask for some permission you can just allow basic permissions
Click Allow once or Always allow to confirm the swap.
Once approved, Tower Exchange routes and executes the swap on Arc. Claude will confirm that the swap was successful, showing your updated balances and transaction Swap ID.
Available MCP Tools

Troubleshooting & FAQ
Why is Claude asking for permission?
Claude utilizes a secure tool-use sandbox. When Claude triggers a tool that executes actions on your behalf (such as placing a trade), it prompts you to confirm. You can safely select Allow once or Always allow.
Are my private keys exposed?
No. Neither Claude nor the Tower MCP server ever has access to your private keys or seed phrase. Connection is established via cryptographic wallet signature and permissions are gated by you.
