ReqStorm: Run API Performance Tests from Any MCP Host

Performance testing usually means firing up JMeter, writing artillery scripts, or staring at k6 dashboards. ReqStorm flips that

It's an MCP server that turns performance testing into natural conversation with your AI assistant.

What it does

ReqStorm runs autocannon-powered tests and reports warm-up vs steady-state results, so you can quantify JIT/cache effects instead of hiding them. Seven tools cover the testing spectrum:

• benchmark — quick latency/throughput snapshot (p50/p95/p99/p999)
• smoke — 5-second sanity check with response validation
• load-test — sustained load with SLO thresholds (maxP95, maxP99, maxErrorRate)
• spike — surge testing with recovery-time measurement
• soak — 30-min runs that catch memory leaks and drift
• stress-test — auto-ramp to find the breaking point
• compare — A/B between two endpoints

Get started
