Create a new task in a specific Microsoft Todo list. A task is the main todo item that can have a title, description, due date, and other properties.
AI agents use create-task to create or update resources in Microsoft Todo MCP Service — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Microsoft Todo MCP Service environment.
Creating a task is a reversible write operation—tasks can be deleted or modified later. It modifies user data (task lists) but does not execute arbitrary code, delete data irreversibly, or affect financial systems. The severity is medium because malicious task creation could clutter or confuse a user's task system, but the impact is limited in scope and fully recoverable.
From the tool's definition Tool name 'create-task' and description 'Create a new task in a specific Microsoft Todo list' explicitly indicate data creation. The tool adds new records to a user's task management system.
Documented attack patterns abuse exactly the kind of access create-task gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Microsoft Todo MCP Service, and nothing reaches the server without passing your rules. This is the rule we recommend for create-task:
{
"version": "1",
"default": "deny",
"tools": {
"create-task": {
"limits": [
{
"counter": "create-task_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-task 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 in a specific Microsoft Todo list. A task is the main todo item that can have a title, description, due date, and other properties. It is categorised as a Write tool in the Microsoft Todo MCP Service MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Microsoft Todo MCP Service MCP server in PolicyLayer and add a rule for create-task: 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 Microsoft Todo MCP Service. Nothing to install.
create-task 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 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. 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 is provided by the Microsoft Todo MCP Service MCP server (jhirono/todomcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Microsoft Todo MCP Service, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
