List all todo items stored in the YAML file
AI agents call list_todos to retrieve information from MCP Todo List Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing todo items without side effects. It performs no state changes, data modification, or irreversible operations. The sibling tools (add_todo, complete_todo, delete_todo) perform write and destructive operations, but list_todos is purely informational. Low severity because even if misused, an AI agent cannot cause harm by merely listing items.
From the tool's definition Tool name 'list_todos' and description 'List all todo items stored in the YAML file' indicate retrieval-only operation with no modification or deletion of data.
Attacks that exploit this kind of access
List all todo items stored in the YAML file. It is categorised as a Read tool in the MCP Todo List Manager MCP Server, which means it retrieves data without modifying state.
Register the MCP Todo List Manager MCP server in PolicyLayer and add a rule for list_todos: 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 MCP Todo List Manager. Nothing to install.
list_todos 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_todos 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_todos. 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_todos is provided by the MCP Todo List Manager MCP server (sk0t31n0s/mcptodo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
