FAQ: AI agents and money

Short answers, each with its sources. The linked pages have the details. Anything the sources do not confirm stays “unknown”. Not investment advice.

Which brokers let AI agents trade?

All five launch brokers publish an official MCP server for AI agents: Alpaca, Coinbase, Interactive Brokers, Robinhood and Webull.12345 They differ on who approves each order. Details: Trading.

Who approves an AI agent’s trades?

It depends on the broker. Robinhood limits the agent to a separate account you fund, and per-order approval is an optional toggle.46 With Webull’s hosted Cloud MCP, you confirm each trade in the Webull app.7 At Interactive Brokers, by default the AI drafts instructions you review and submit.38 Alpaca documents no broker-side approval, so approval has to live in your agent or client.910 See approval models.

Can I test a trading agent without real money?

Sometimes. Alpaca has a separate paper trading endpoint with a $100K simulated balance.1110 Webull’s local OpenAPI MCP defaults to the UAT sandbox; a sandbox for its Cloud MCP is unknown.12 For Robinhood, Coinbase and Interactive Brokers, a paper option for agents is unknown. See the launch-broker comparison.

Can an AI agent pay for things for me?

Yes, through several programs, each with limits. Visa lets approved agent builders pay with tokenized Visa credentials, under purchase instructions the consumer approved.13 Mastercard lets only registered agents pay, using agentic tokens.1415 Stripe’s shared payment tokens carry usage and expiry limits.16 Robinhood’s Agentic Credit Card asks you to approve each purchase or set a monthly limit.17 See Payments.

Do banks let outside AI agents into my account?

Often not fully, according to news reports. They say several big US banks block outside agents that log in with a customer’s password,1819 and that most allow read-only access at best, while some build their own AI tools.2018 See Banks and outside agents.

Can AI tools for financial advisors place trades?

Not on their own, for the two whose official pages address it. Anthropic’s solutions page says “Claude doesn’t place trades or move money.”21 Nitrogen’s agents page says “Every action still requires your approval.”22 Wells Fargo’s launch release describes AI Teammate as search and summary help for advisor teams; whether it can place trades is unknown.23 See Advisor agents.
