AI agents call read_page to retrieve information from Notion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves page content from Notion without creating, modifying, deleting, or executing any operations. It is a straightforward data query operation with no destructive or side-effect capacity. The low severity reflects that misuse would only expose existing information the agent already has access to read.
From the tool's definition Tool name is 'read_page' and description states 'Read a regular page'. The verb 'read' and the operation 'Read' clearly indicate data retrieval with no modification or side effects.
Documented attack patterns abuse exactly the kind of access read_page gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Notion MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for read_page:
{
"version": "1",
"default": "deny",
"tools": {
"read_page": {}
}
}read_page is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read a regular page. It is categorised as a Read tool in the Notion MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Notion MCP Server MCP server in PolicyLayer and add a rule for read_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 Notion MCP Server. Nothing to install.
read_page is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the read_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 read_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.
read_page is provided by the Notion MCP Server MCP server (v-3/notion-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
