Agentic Wallet MCP Tools - Coinbase Developer Documentation

Your AI agent can use these tools to manage your wallet and make payments. You talk to your agent in natural language—the agent uses these tools behind the scenes.

Wallet tools

Tool	Description
Get wallet address	Returns your wallet address
Get wallet balance	Shows your token balances (USDC, etc.)
Show wallet app	Opens the wallet interface for sign-in, funding, and browsing services
Check sign-in status	Checks if you’re signed in and provides next steps if not

Payment tools

Tool	Description
List Bazaar resources	Discovers available x402 services your agent can pay for
Get resource details	Gets full documentation for a specific service
Make an x402 request	Makes an API call and handles payment automatically
Check payment requirements	Checks what an endpoint costs without paying

What agents CAN’T do

These features exist in the wallet UI, but agents cannot access them. Only you can:

Set spending limits — Configure max spend per call and per session in the wallet UI. Agents respect these limits but can’t change them.
Transfer funds — Send USDC to other addresses. Agents can only pay for x402 services, not send to arbitrary addresses.
Add funds — Use Coinbase Onramp to add USDC. Agents can’t initiate onramp flows.
