AI agents call getBulkPosts to retrieve information from X Com 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 existing posts without any side effects. It is a read-only operation that queries data from X.com. No posts are created, modified, deleted, or any financial transactions occur. The operation has minimal blast radius even if misused by an AI agent, as it only exposes publicly available or authorized post content. The batching of up to 100 posts does not elevate the risk category.
From the tool's definition Tool name 'getBulkPosts' and description 'Retrieve up to 100 posts by their IDs' indicate a data retrieval operation with no modification or deletion of data.

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

Start from X Com MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
