MCP-Atlas: A Large-Scale Benchmark for Tool-Use Competency with Real MCP Servers
Leaderboard | MCP Atlas Paper | Github
Dataset Summary
This public release is a subset of 500 sample tasks from the MCP Atlas Benchmark dataset. MCP Atlas is a large-scale benchmark for evaluating tool-use competency, comprising 36 real MCP servers and 220 tools. Tasks are designed to assess tool-use competency in realistic, multi-step workflows. Tasks use natural language prompts that avoid naming specific tools or servers, requiring agents to identify and orchestrate 3-6 tool calls across multiple servers.
This dataset closely follows the distributions of the full benchmark, utilizing all 36 servers and 220 tools. The public release maintains 3-6 tool calls per task as well. The data is contained in a single parquet file.
Dataset Structure
An example of a MCP Atlas datum is as follows:
- TASK: (str) A unique 24 character ID.
- ENABLED_TOOLS (str): A controlled subset of 10-25 tools exposed to the agent per task.
- PROMPT: (str) A single-turn, natural-language request requiring multiple tool calls.
- GTFA_CLAIMS: (str) A set of distinct, independently verifiable claims forming a comprehensive response grounded in tool outputs.
- TRAJECTORY: (str) The sequence of tool calls (names, methods, dependencies, arguments, outputs) resolving the task.
Use
An eval harness is released alongside the dataset to allow independent scrapes and evaluations of model responses. PROMPT and ENABLED_TOOLS are exposed to the model endpoint of your choice (API keys not provided). Model responses are evaluated via the claims-based rubric GTFA_CLAIMS to determine a coverage score. TRAJECTORY data can be used for post-eval diagnostics. (Note: diagnostics results and processes are not included in the public release)
