AI agents use add_todo to create or update resources in Notion MCP Integration — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Notion MCP Integration environment.
This tool creates or modifies data (adds a todo item) in a reversible manner—the item can be deleted or edited later. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. Write category is appropriate for data creation operations.
From the tool's definition Tool name 'add_todo' and description 'Add a new todo item' indicate creation of new data in the todo list without irreversible destruction or financial impact.
Documented attack patterns abuse exactly the kind of access add_todo gives an agent:
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 add_todo:
{
"version": "1",
"default": "deny",
"tools": {
"add_todo": {
"limits": [
{
"counter": "add_todo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_todo stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Add a new todo item. It is categorised as a Write tool in the Notion MCP Integration MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Notion MCP Integration MCP server in PolicyLayer and add a rule for add_todo: 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.
add_todo is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_todo 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 add_todo. 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.
add_todo 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.
