List all pending todos that are past their due date
AI agents call List-Overdue to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays overdue todo items without creating, modifying, deleting, or executing any operations. It is purely a read operation similar to other list tools on the server (List-All-Todos, List-Completed-Todos, etc.). The blast radius of misuse is minimal—an AI could at worst retrieve information the user likely already has access to.
From the tool's definition Tool name 'List-Overdue' and description 'List all pending todos that are past their due date' indicate a retrieval/query operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access List-Overdue gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Todos, and nothing reaches the server without passing your rules. This is the rule we recommend for List-Overdue:
{
"version": "1",
"default": "deny",
"tools": {
"List-Overdue": {}
}
}List-Overdue is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all pending todos that are past their due date. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for List-Overdue: 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 Todos. Nothing to install.
List-Overdue 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 List-Overdue 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 List-Overdue. 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.
List-Overdue is provided by the Todos MCP server (tomelliot/todos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Todos, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
