Retrieve a list of unresolved comments from a Notion page or block. Requires the integration to have
AI agents call notion_retrieve_comments 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 queries and returns existing comment data from Notion pages or blocks. It performs a read-only operation with no capability to create, modify, delete, or execute actions. The description explicitly states 'Retrieve' which is a classic Read operation. No destructive, financial, or execution capabilities are present. Severity is low because retrieving comments poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'notion_retrieve_comments' and description 'Retrieve a list of unresolved comments' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access

Register the Notion MCP Server MCP server in PolicyLayer and add a rule for notion_retrieve_comments: 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_retrieve_comments 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_retrieve_comments 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_retrieve_comments. 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_retrieve_comments is provided by the Notion MCP Server MCP server (tkc/notion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
