Get tasks filtered by OmniFocus tags (labels like @home, @work, @urgent). Use this for tag-based filtering, NOT for custom perspective names. Tags are labels assigned to individual tasks.
AI agents call get_tasks_by_tag to retrieve information from OmniFocus MCP Enhanced without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries tasks from OmniFocus based on tag filters. It performs a read-only operation with no side effects—it does not create, modify, delete, or execute any irreversible actions. The blast radius of misuse is minimal, limited to viewing filtered task data that the AI agent likely already has access to through other read operations.
From the tool's definition Tool description explicitly states 'Get tasks filtered by OmniFocus tags' and 'Use this for tag-based filtering'. The verb 'Get' and the filtering operation indicate data retrieval with no modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access get_tasks_by_tag gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OmniFocus MCP Enhanced, and nothing reaches the server without passing your rules. This is the rule we recommend for get_tasks_by_tag:
{
"version": "1",
"default": "deny",
"tools": {
"get_tasks_by_tag": {}
}
}get_tasks_by_tag is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get tasks filtered by OmniFocus tags (labels like @home, @work, @urgent). Use this for tag-based filtering, NOT for custom perspective names. Tags are labels assigned to individual tasks. It is categorised as a Read tool in the OmniFocus MCP Enhanced MCP Server, which means it retrieves data without modifying state.
Register the OmniFocus MCP Enhanced MCP server in PolicyLayer and add a rule for get_tasks_by_tag: 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 OmniFocus MCP Enhanced. Nothing to install.
get_tasks_by_tag 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 get_tasks_by_tag 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 get_tasks_by_tag. 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.
get_tasks_by_tag is provided by the OmniFocus MCP Enhanced MCP server (jqlts1/omnifocus-mcp-enhanced). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OmniFocus MCP Enhanced, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
