What is MCPMark?

MCPMark is a benchmark for how well a model acts as a general-purpose agent. The official description says: "MCPMark - GitHub MCP v0.30.3; Playwright responses truncated at 32K tokens". Below we describe in simple words what benchmarks of this type generally examine.

What does it test?

MCPMark measures how well a model acts as a general-purpose agent. In detail, it checks:

  • solving long, multi-step tasks with many intermediate decisions
  • using tools correctly (browsers, terminals, APIs, calendars, other apps)
  • adapting when something unexpected happens mid-task
  • staying on goal over long task horizons instead of wandering off

How to read the score

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.
