AI agents call get_draft to retrieve information from IMAP Email MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves draft email content by unique identifier. It performs a query operation with no side effects—no data is created, modified, deleted, or executed. While draft emails may contain sensitive information, the tool itself is purely retrieving existing data without the ability to send, modify, or destroy it. This is a straightforward Read category tool with low severity.
From the tool's definition Tool name 'get_draft' and description 'Get a specific draft email by UID' indicate retrieval of existing data with no modification or deletion. The verb 'Get' is a read operation.
Documented attack patterns abuse exactly the kind of access get_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 get_draft:
{
"version": "1",
"default": "deny",
"tools": {
"get_draft": {}
}
}get_draft is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a specific draft email by UID. It is categorised as a Read tool in the IMAP Email MCP Server MCP Server, which means it retrieves data without modifying state.
Register the IMAP Email MCP Server MCP server in PolicyLayer and add a rule for get_draft: 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 Email MCP Server. Nothing to install.
get_draft 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_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 get_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.
get_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.
Start from IMAP Email MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
