reaatech/mcp-load-test

These packages give you a purpose-built load testing framework for MCP (Model Context Protocol) servers, with a CLI, orchestration engine, transport clients, and analysis tooling. You would adopt them to stress-test MCP servers under realistic concurrent workloads—modeling user behavior with weighted tool-call patterns, detecting breaking points, and producing latency histograms with letter grades. The framework is transport-aware, meaning it accounts for the different concurrency profiles of StreamableHTTP, SSE, and stdio, and uses session-based closed-loop concurrency where long-lived sessions continuously execute patterns with think-time delays and stateful context.
