X Grants AI Agents Full API Access Without Permission Controls

X's MCP server represents a significant departure from other platform integrations by exposing its full API without permission controls—directly exposing your reputation rather than just infrastructure. Tools like post creation, direct messaging, and content deletion can cause irreversible damage if an AI agent hallucinates or falls victim to prompt injection. The 131 exposed tools lack any access control, rate limiting, or scoping at the MCP layer, making this integration fundamentally different from closed-system integrations.
