Coinbase adds trade limits and an auto-stop for AI agents that trade on its platform

Coinbase has added a set of spending and risk controls for people who let AI agents place trades on their accounts. In a blog post dated 11 November, the exchange said the new Agent Controls in Coinbase for Agents, its MCP-based service for researching and trading through outside AI tools, let users set trading limits, choose permissions and decide when an agent stops. The company announced the launch the same day in a post on X, describing them as controls "your agent can't override."

The four controls

According to Coinbase, the package includes:

• A maximum trade size, set in US dollars for each trade.
• A 24-hour volume limit; any trade that would exceed the cap does not go through.
• An auto-stop, which halts new trades if a portfolio falls past a chosen percentage loss, until the user turns trading back on in the Coinbase app.
• Product permissions, marked "coming soon," to choose which categories an agent can trade, such as crypto, equities or derivatives.

Where the limits live

Coinbase said the controls run on its own servers rather than inside the agent, and can only be changed from the user's logged-in account in the app or on the web, which is protected by password and two-factor authentication. That design, it said, means an agent cannot change its own limits. The post carries a disclaimer that AI agents may make mistakes and that users direct and bear the risk of transactions their agents execute.

Analysis

Brokerages and exchanges are starting to let customers hand order entry to AI assistants, and server-side limits like these are one way platforms are trying to contain the risk of a misbehaving agent. Coinbase has not published usage figures for Coinbase for Agents.
