MCP Agent Trajectory Benchmark
A benchmark dataset of 49 MCP (Model Context Protocol) agent trajectories (38 single-pass + 11 multi-conv) with complete tool-use traces in the ATIF v1.2 (Agent Trajectory Interchange Format) format. Each agent operates in a distinct business domain with custom tools, realistic user conversations, and full execution traces.
Designed for training and evaluating tool-use / function-calling capabilities of LLMs.

MCP-Atlas-Easy
An easy, single-tool-call benchmark for pretrained (base) language models, derived from ScaleAI/MCP-Atlas.
MCP-Atlas evaluates instruction-tuned agents on multi-step tool orchestration (3–6 calls per task across 36 real MCP servers). MCP-Atlas-Easy strips that down to the simplest possible form of the same skill: one tool spec, one trivially unambiguous request, one correct tool call, then stop. This makes it usable as a completion-style eval for base models with… See the full description on the dataset page: https://huggingface.co/datasets/marin-community/mcp-atlas-easy.gspc-mcp

Summary
72 constructible gold records of grounded MCP tool use over monophonic audio analysis. Each record pairs a 4-note right-hand reduction of a public-domain library phrase with a seeded synthetic take and a gold verdict (match, pitch fail/warn, timing fail/pass, missed, extra, in-tune vibrato, or nothing-to-grade silence).

Two things you can do with this.
Check our arithmetic. The repo has the readout scripts, the preregistrations and the
intervals — but the generations they were computed from are ~51 MB and were never committed, so
a clone got the conclusions and no way to recompute them. These are those files, unfiltered.

What is MCP?
Model Context Protocol is Anthropic's open standard for connecting LLMs to external tools and data sources. MCP servers expose tools that AI assistants can call to interact with filesystems, databases, APIs, and services.

KASA MCP — Indirect-Channel Agent Probes
Four probes measuring whether untrusted content — not the operator — can steer a local model that sits inside an agent pipeline. Four model configurations, five runs each, 80 rows.
The dataset exists because it caught a failure in the architecture that produced it. The headline result is A8: 20 out of 20 runs compromised, on every configuration tested.
