AI agents may call version_discard_document to permanently remove or destroy resources in Sanity. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call version_discard_document in a loop, permanently destroying resources in Sanity. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access version_discard_document gives an agent. Each links to the full case and the policy that stops it:

Discard a document version from a release. It is categorised as a Destructive tool in the Sanity MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sanity MCP server in PolicyLayer and add a rule for version_discard_document: 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 Sanity. Nothing to install.
version_discard_document 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 version_discard_document 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 version_discard_document. 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.
version_discard_document is provided by the Sanity MCP server (@@sanity/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
