AI agents call notion_search to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation on Notion pages and databases. It queries existing data by title but does not create, modify, delete, or execute any operations with side effects. The scope is limited to retrieval, making it a Read category tool with low severity since misuse would only expose information the user has access to within their Notion workspace.
From the tool's definition Tool name 'notion_search' and description 'Search for pages and databases by title' indicate a query/search operation that retrieves information without modifying data.
Documented attack patterns abuse exactly the kind of access notion_search 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_search:
{
"version": "1",
"default": "deny",
"tools": {
"notion_search": {}
}
}notion_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for pages and databases by title. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for notion_search: 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_search 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 notion_search 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_search. 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_search 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.
