Coinbase Wallet MCP
for LuumenAI

Inspect wallets, check balances, and send onchain transactions as approved steps

Connect Coinbase Wallet MCP and Luumen can read your Base Account and agent wallets the way you would: portfolio value per asset, delegation status and spend policy, transaction history, token lookups, and read-only JSON-RPC calls. When a transfer, swap, signature, or payment is needed, Luumen shows the exact call first and waits for your approval. Authentication uses OAuth with dynamic client registration.

Questions

How does LuumenAI connect to Coinbase Wallet MCP?

Authorize once with OAuth 2.0. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.

Can LuumenAI change things in Coinbase Wallet MCP on its own?

This connection exposes write actions such as complete x402 request, fund, initiate x402 request, send, and more. For connected tools, admins configure which actions may run automatically and which require approval, within the access granted to the user. Review the configured approval policy before enabling write access.

Who gets access to the integration?

You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.

Is there an audit trail?

Every call to Coinbase Wallet MCP — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
