WHAT IT DOES

What gcp_billing_list_accounts does on GCP MCP Server

RISK

Why gcp_billing_list_accounts is rated Low

This is a read-only operation that queries and lists billing account metadata. However, billing account information is sensitive—it reveals financial infrastructure, cost centers, and organizational structure—making it valuable for reconnaissance. The medium severity reflects that while no direct harm occurs from reading, the information exposed could inform follow-up financial or destructive attacks.

From the tool's definition Tool name 'gcp_billing_list_accounts' with description 'List all billing accounts accessible to the user' performs a retrieval operation with no side effects.
