Delete a Notion block.
AI agents call delete_block to permanently remove resources in Notion MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes a block from a Notion page. Blocks are fundamental content units (text, images, tables, etc.), and deletion cannot be undone through the tool itself. While not a total database wipe, deleting blocks causes permanent loss of user content. An AI agent with this capability could accidentally or maliciously destroy significant portions of a user's Notion workspace.
From the tool's definition Tool name is 'delete_block' and description states 'Delete a Notion block.' The verb 'delete' is explicitly destructive.
Attacks that exploit this kind of access
Delete a Notion block. It is categorised as a Destructive tool in the Notion MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Notion MCP Server MCP server in PolicyLayer and add a rule for delete_block: 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 Notion MCP Server. Nothing to install.
delete_block 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_block 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_block. 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_block is provided by the Notion MCP Server MCP server (lrgex/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
