AI agents call show_all_todos to retrieve information from Notion MCP Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only displays/retrieves todo items from the user's Notion database. It does not create, modify, delete, execute code, or move money. It is a straightforward read operation with minimal risk; the worst-case misuse would be information disclosure of the user's own todo list.
From the tool's definition Tool name is 'show_all_todos' and description states 'Show all todo items from Notion' — this retrieves/queries existing data with no side effects or modifications.

PolicyLayer is an MCP gateway — it sits between your AI agents and Notion MCP Integration, and nothing reaches the server without passing your rules. This is the rule we recommend for show_all_todos:
{
"version": "1",
"default": "deny",
"tools": {
"show_all_todos": {}
}
}show_all_todos is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Notion MCP Integration MCP server in PolicyLayer and add a rule for show_all_todos: 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 Integration. Nothing to install.
show_all_todos 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 show_all_todos 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 show_all_todos. 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.
show_all_todos is provided by the Notion MCP Integration MCP server (ruijian-zha/notion_mcp_advanced). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Notion MCP Integration, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
