AI agents call list_drafts to retrieve information from X(Twitter) 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 and queries existing draft data without modifying, deleting, or publishing anything. It is a pure read operation with minimal security risk, even in a multi-user or compromised context, as it only exposes draft content that is not yet published.
From the tool's definition Tool name 'list_drafts' and description 'List all draft tweets and threads' indicate data retrieval with no side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and X(Twitter) MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_drafts:
{
"version": "1",
"default": "deny",
"tools": {
"list_drafts": {}
}
}list_drafts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
