Delete a static secret.
AI agents call delete_secret to permanently remove resources in Infisical MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion of secrets. Secrets stored in Infisical typically include API keys, credentials, and other sensitive data. Unauthorized deletion would cause immediate data loss and potentially break applications or services dependent on those secrets. This is more severe than Write (reversible modifications) and qualifies as Destructive.
From the tool's definition Tool name is 'delete_secret' and description states it 'Delete a static secret.' This is an irreversible deletion operation on stored secrets, which are sensitive data.
Attacks that exploit this kind of access
Delete a static secret. It is categorised as a Destructive tool in the Infisical MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Infisical MCP server in PolicyLayer and add a rule for delete_secret: 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 Infisical MCP. Nothing to install.
delete_secret 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 delete_secret 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 delete_secret. 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.
delete_secret is provided by the Infisical MCP server (plgonzalezrx8/infisicalmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
