Part of the Stripe MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

WHEN AI AGENTS USE THIS TOOL

AI agents use update_subscription to initiate financial transactions through Stripe. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.

WHY ENFORCE A POLICY ON UPDATE_SUBSCRIPTION

update_subscription moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

RECOMMENDED POLICY

Financial tools involve real money. Block by default and require explicit human approval before enabling.
