AI agents use add_project to create or update resources in OmniFocus MCP Enhanced — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OmniFocus MCP Enhanced environment.
This tool creates a new project in OmniFocus, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or trigger external side effects. The impact is limited to adding a single project entry in the task management system. Low severity because misuse would only result in unwanted project entries that can be easily deleted.
From the tool's definition Tool name is 'add_project' and description states 'Add a new project to OmniFocus'. The verb 'Add' indicates data creation, which is a Write operation.
Documented attack patterns abuse exactly the kind of access add_project 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 add_project:
{
"version": "1",
"default": "deny",
"tools": {
"add_project": {
"limits": [
{
"counter": "add_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_project stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Add a new project to OmniFocus. It is categorised as a Write tool in the OmniFocus MCP Enhanced MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the OmniFocus MCP Enhanced MCP server in PolicyLayer and add a rule for add_project: 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.
add_project is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_project 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 add_project. 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.
add_project 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.
