AI agents call getRetweets 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 queries and retrieves retweet data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that has no side effects and poses minimal security risk if misused by an agent.
From the tool's definition Tool name 'getRetweets' and description 'Get posts that retweet a specific post' indicate retrieval of existing data with no modification or side effects.

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 getRetweets:
{
"version": "1",
"default": "deny",
"tools": {
"getRetweets": {}
}
}getRetweets 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.
