What notion_append_block_children does on ScopeGate
AI agents use notion_append_block_children to create or update resources in ScopeGate, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScopeGate environment.
Why notion_append_block_children is rated Medium
This tool adds new content to existing Notion pages or blocks. It is a write operation (creating/modifying data) that is reversible in principle (blocks can be deleted), so it falls under Write rather than Destructive. Misuse could add unwanted content to pages at scale, making severity medium.
From the tool's definition 'Append content blocks to a Notion page or block' — creates new content by appending blocks
Attacks that exploit this kind of access
The rule that runs notion_append_block_children safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScopeGate, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For notion_append_block_children, this is the rule to start with:
notion_append_block_children stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScopeGate, apply this rule, and every notion_append_block_children call is checked against it from then on.
