Delete a block
AI agents call notion_delete_block to permanently remove resources in MCP Notion Server (@suncreation) — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting blocks in Notion permanently removes content and is not reversible through standard API operations. While not as critical as deleting entire databases, block deletion is destructive in nature and has a moderate blast radius if an AI agent is misused to delete important content. This tool permits irreversible data loss and therefore fits the Destructive category rather than Write (which is reversible).
From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a block'. Deletion is inherently irreversible and cannot be undone through the tool itself.
Attacks that exploit this kind of access
Delete a block. It is categorised as a Destructive tool in the MCP Notion Server (@suncreation) MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Notion Server (@suncreation) MCP server in PolicyLayer and add a rule for notion_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 MCP Notion Server (@suncreation). Nothing to install.
notion_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 notion_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 notion_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.
notion_delete_block is provided by the MCP Notion Server (@suncreation) MCP server (suncreation/mcp-notion-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
