Create a new task list (top-level container) in Microsoft Todo to help organize your tasks into categories or projects.
AI agents use create-task-list to create or update resources in My MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your My MCP environment.
This tool creates a new organizational structure (a task list) in Microsoft Todo. It is reversible (task lists can be deleted via the sibling tool "delete-task-list"), so it falls under Write rather than Destructive.
From the tool's definition Tool name is "create-task-list" and description states "Create a new task list (top-level container)" — the verb 'Create' and the explicit action to add a new container demonstrates data creation.
Documented attack patterns abuse exactly the kind of access create-task-list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and My MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create-task-list:
{
"version": "1",
"default": "deny",
"tools": {
"create-task-list": {
"limits": [
{
"counter": "create-task-list_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-task-list 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.

Create a new task list (top-level container) in Microsoft Todo to help organize your tasks into categories or projects. It is categorised as a Write tool in the My MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the My MCP server in PolicyLayer and add a rule for create-task-list: 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 My MCP. Nothing to install.
create-task-list 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 create-task-list 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 create-task-list. 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.
create-task-list is provided by the My MCP server (jordanburke/microsoft-todo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from My MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
