AI agents call list-active-todos to retrieve information from Todo List MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves todo items without modifying, deleting, or executing any operations. It is purely informational and has no destructive or side-effect-causing capabilities. The low severity reflects minimal blast radius if misused by an AI agent—at worst, information disclosure of task data.
From the tool's definition Tool name 'list-active-todos' and description 'List all non-completed todos' indicate a retrieval operation with no side effects. 'List' is explicitly enumerated as a Read category example.

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