From the README
<div align="center"> # MCPMark: Stress-Testing Comprehensive MCP Use </div> An evaluation suite for agentic models in real MCP tool environments (Notion / GitHub / Filesystem / Postgres / Playwright). MCPMark provides a reproducible, extensible benchmark for researchers and engineers: one-command tasks, isolated sandboxes, auto-resume for failures, unified metrics, and aggregated reports. > 🚀 **MCPMark Verified is now the default.** The standard tasks in this repository are the Verified set — every environment version-pinned and every verifier stabilized. Results from earlier task versions are deprecated and not directly comparable, so please report new numbers as **MCPMark Verified**. On the Verified set, `gpt-5.5` (xhigh) leads at **92.9%** and `kimi-k2.7` reaches **81.1%**. See [#264](https://github.com/eval-sys/mcpmark/pull/264). ## News - 🚀 **12 Jun** — **MCPMark Verified** is now the default task set: every environment version-pinned and every verifier stabilized.
