Close a Brighty account. The account must be empty (zero balance) and not the primary account. This is irreversible.
AI agents call brighty_terminate_account to permanently remove resources in Brighty MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
While this tool requires preconditions (zero balance, not primary account), account termination is inherently irreversible and represents permanent destruction of a financial account structure. This is more severe than Write (reversible modifications) or Execute (effects depend on arguments). Combined with the banking context and irreversible nature, this warrants Destructive classification with critical severity.
From the tool's definition Tool description explicitly states 'Close a Brighty account' and 'This is irreversible.' The action terminates an account, which cannot be undone.
Attacks that exploit this kind of access
Close a Brighty account. The account must be empty (zero balance) and not the primary account. This is irreversible. It is categorised as a Destructive tool in the Brighty MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Brighty MCP Server MCP server in PolicyLayer and add a rule for brighty_terminate_account: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Brighty MCP Server. Nothing to install.
brighty_terminate_account is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the brighty_terminate_account rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for brighty_terminate_account. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
brighty_terminate_account is provided by the Brighty MCP Server MCP server (razz-team/brighty-agent-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
