# QueueSim

> Use this tool when you need to simulate and analyze queueing systems, such as call centers or waiting rooms, to predict wait times and optimize resource allocation. QueueSim takes inputs like arrival rates, service rates, and server counts, and outputs realistic wait time estimates based on discrete event simulations. It's ideal for use cases where you want to model complex queueing scenarios, including priority tiers, abandonment, and server outages, and get accurate results without requiring authentication or API keys.

## Description

QueueSim is a free Model Context Protocol server that gives Claude — and any MCP-speaking AI — the ability to run real discrete event queueing simulations inside a conversation. Ask "I run a 3-agent call center, 30 calls/hr, 4-min handle time — what's my wait?" and get an actual number from a simulator, not a guess.

Six tools cover the common cases: direct M/M/c with arrival rate / service rate / server count, four preset scenarios (single server, coffee shop, ER waiting room, call center) with optional overrides, plus two textbook explainers covering basic queueing theory and six common patterns beyond M/M/c (abandonment, priority tiers, overflow routing, skills-based routing, compound service, server outages).

Free, no auth, no API key. By ChiAha — 35 years of discrete event simulation. For modeling beyond M/M/c against your own data, contact queuesim@chiaha.com.
