AI agents use create_draft to create or update resources in IMAP Email MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your IMAP Email MCP Server environment.
This tool creates new data (email draft) but does not send it or make it irreversible. It is a Write operation because drafts are modifiable and deletable. Severity is medium because while draft creation itself is benign, it operates in the context of an email system where misuse could compose fraudulent or harmful messages—though the draft stage provides an opportunity for human review before sending.
From the tool's definition Tool name is 'create_draft' and description states it 'Create a new draft email'. The server description confirms it enables 'draft handling' as part of mailbox management.
Documented attack patterns abuse exactly the kind of access create_draft gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and IMAP Email MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_draft:
{
"version": "1",
"default": "deny",
"tools": {
"create_draft": {
"limits": [
{
"counter": "create_draft_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_draft 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.

Yes. Add a rate_limit block to the create_draft 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_draft. 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_draft is provided by the IMAP Email MCP Server MCP server (jdickey1/imap-email-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
