AI agents use create_task to create or update resources in IMAP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your IMAP MCP Server environment.
The tool name 'create_task' indicates a data creation action. In the context of an email/calendar management server, tasks are typically reversible entities that can be edited or deleted. This aligns with the Write category (creates or modifies data reversibly).
From the tool's definition Tool named 'create_task' with empty description. Based on server context (IMAP email management) and sibling tools that include delete_email, flag_email, move_email, and mark_as_read, this tool likely creates a new task object (reversible data creation).
Documented attack patterns abuse exactly the kind of access create_task gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and IMAP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_task:
{
"version": "1",
"default": "deny",
"tools": {
"create_task": {
"limits": [
{
"counter": "create_task_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_task 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.

create_task. It is categorised as a Write tool in the IMAP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the IMAP MCP Server MCP server in PolicyLayer and add a rule for create_task: 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 IMAP MCP Server. Nothing to install.
create_task 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 create_task 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 create_task. 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.
create_task is provided by the IMAP MCP Server MCP server (non-dirty/imap-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
