How scalable is an MCP Server under load?
How scalable is an MCP Server under load?
It depends on the tool being wrapped. For example:
- A lightweight lookup tool (like WHOIS) can handle 1000+ concurrent requests
- A port scanner or PDF parser may need container isolation and queueing
Use async workers (Celery, FastAPI), message queues (RabbitMQ), and horizontal scaling via Docker Swarm/K8s for production workloads.
