Delete a specific version of a document.
AI agents call delete_document_version to permanently remove resources in Mycase — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs irreversible deletion of document data. While it targets a specific version rather than an entire document, deletion operations that cannot be undone fall into the Destructive category. In a law firm context, documents often contain critical evidence, client communications, and case materials—loss of even a version could have serious consequences.
From the tool's definition Tool name explicitly states 'delete_document_version' and description confirms 'Delete a specific version of a document.' This is an irreversible deletion operation.
Attacks that exploit this kind of access
Delete a specific version of a document. It is categorised as a Destructive tool in the Mycase MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mycase MCP server in PolicyLayer and add a rule for delete_document_version: 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 Mycase. Nothing to install.
delete_document_version 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_document_version 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_document_version. 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_document_version is provided by the Mycase MCP server (rosenadvertising/mycase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
