Delete a document. Requires write token.
AI agents call sanity_delete to permanently remove resources in Sanity MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes data (a document) from the Sanity content management system. Deletion is inherently irreversible and cannot be undone without restoration from backups. This meets the Destructive category criterion: 'irreversibly deletes or overwrites data, or actions that cannot be undone (delete, drop, purge, force-push).' An AI agent with misuse could destroy critical content without recovery.
From the tool's definition Tool name is 'sanity_delete' and description states it 'Delete a document.' This is irreversible deletion of data.
Attacks that exploit this kind of access
Delete a document. Requires write token. It is categorised as a Destructive tool in the Sanity MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sanity MCP Server MCP server in PolicyLayer and add a rule for sanity_delete: 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 MCP Server. Nothing to install.
sanity_delete 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 sanity_delete 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 sanity_delete. 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.
sanity_delete is provided by the Sanity MCP Server MCP server (purple-horizons/sanity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
