List all tasks in OmniFocus. The task full name is the full heirarchy of the task, including parent tags.
AI agents call list_tasks to retrieve information from MCP OmniFocus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves task information from OmniFocus. It performs no mutations, deletions, or external operations. The blast radius of misuse is minimal—an agent could only access existing task data, which does not expose sensitive operations.
From the tool's definition Tool name is 'list_tasks' and description states it 'List all tasks in OmniFocus'. The verb 'list' is explicitly a read operation that retrieves data without modification.
Attacks that exploit this kind of access
List all tasks in OmniFocus. The task full name is the full heirarchy of the task, including parent tags. It is categorised as a Read tool in the MCP OmniFocus MCP Server, which means it retrieves data without modifying state.
Register the MCP OmniFocus 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 MCP OmniFocus. 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 MCP OmniFocus MCP server (someposer/mcp-omnifocus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
