4. Resource Exhaustion

Because MCP Servers can launch heavy tools (e.g., nmap, masscan, or enrichment queries), they can be abused to overload resources.

Example Malicious Input:

{
  "scan_type": "udp_full",
  "targets": ["10.0.0.0/8"],
  "threads": 10000
}

Such input can spike CPU, memory, and network usage, leading to denial-of-service (DoS) conditions.

Risk: Even without data theft, an attacker can make the MCP Server unusable, disrupt SOC workflows, and increase cloud costs.

Mitigation:

• Apply strict rate limiting and concurrency caps.
• Use job queues with timeout and cancellation policies.
• Auto-ban abusive API keys or IPs.
