Search across Notion pages and databases
AI agents call notion_search 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.
The search functionality only queries and retrieves data from Notion without modifying, deleting, or executing operations. This is a classic Read operation. The severity is low because search operations have minimal blast radius even if misused — an AI agent can only discover information an authorized user already has access to.
From the tool's definition Tool name is 'notion_search' and description states 'Search across Notion pages and databases' — a retrieval operation with no side effects.
Attacks that exploit this kind of access

Register the Notion MCP Server 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 Notion MCP Server. 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 Notion MCP Server MCP server (shameerpc5029/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
