Create a new page in a Notion database or as a child of another page
AI agents use notion_create_page to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
This tool creates new pages in Notion, which is a reversible write operation. It modifies the user's Notion workspace by adding new content, but the action can be undone (pages can be deleted).
From the tool's definition Tool description states 'Create a new page in a Notion database or as a child of another page' — the verb 'create' and capability to add new data structures indicate write/modification of data.
Documented attack patterns abuse exactly the kind of access notion_create_page gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for notion_create_page:
{
"version": "1",
"default": "deny",
"tools": {
"notion_create_page": {
"limits": [
{
"counter": "notion_create_page_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}notion_create_page 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.

Create a new page in a Notion database or as a child of another page. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for notion_create_page: 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 Sage MCP. Nothing to install.
notion_create_page is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the notion_create_page 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_create_page. 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_create_page is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
