Lists tasks in a specific To Do list. By default excludes completed tasks.
AI agents call list-tasks to retrieve information from Outlook Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries task data from Outlook To Do lists without creating, modifying, or deleting any data. It is a read-only operation with minimal security impact even if misused by an agent, as it only exposes existing task information accessible to the authenticated user.
From the tool's definition Tool name 'list-tasks' and description 'Lists tasks in a specific To Do list' indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Lists tasks in a specific To Do list. By default excludes completed tasks. It is categorised as a Read tool in the Outlook Assistant MCP Server, which means it retrieves data without modifying state.
Register the Outlook Assistant MCP server in PolicyLayer and add a rule for list-tasks: 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 Outlook Assistant. Nothing to install.
list-tasks 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-tasks 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-tasks. 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-tasks is provided by the Outlook Assistant MCP server (titanzero/outlook-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
