| # QuantMCP Suite |
|
|
| Task fixtures and frozen tool schemas for the |
| [QuantMCP benchmark](https://github.com/Happynood/quant-mcp-bench), which |
| measures whether quantization-driven function-calling degradation (first |
| shown on curated BFCL/ToolACE schemas by |
| [QuantCall](https://huggingface.co/datasets/happynood/quantcall-suite)) |
| carries over to real, unmodified [Model Context Protocol](https://modelcontextprotocol.io) |
| server tool schemas. |
|
|
| Unlike QuantCall's suite, everything here is originated by this project |
| under MIT — there is no third-party licensed data to gate or manifest-only |
| reference, since every task is hand-written against a real MCP reference |
| server's actual tool surface. |
|
|
| ## Contents |
|
|
| | Path | Description | |
| |------|--------------| |
| | `tasks/u0_tasks.yaml` | 2 smoke tasks against the in-repo toy FastMCP server | |
| | `tasks/u1_filesystem_tasks.yaml` + `tasks/u1_filesystem/` | 13 naturalistic tasks + fixture directory (including a minimal PNG fixture for `read_media_file`) for the official `@modelcontextprotocol/server-filesystem` reference server | |
| | `tasks/u2_git_tasks.yaml` + `tasks/u2_git/repo.tar.gz` | 12 naturalistic tasks + a deterministic fixture git repository (packed as a tarball — a nested `.git` can't be committed as plain content) for the official `mcp-server-git` reference server | |
| | `tasks/u3_sqlite_tasks.yaml` + `tasks/u3_sqlite/fixture.db` | 10 naturalistic tasks + a fixture SQLite database for a self-written FastMCP wrapper (the official sqlite reference server is not currently maintained upstream — see `docs/RUN_REAL.md` in the GitHub repo) | |
| | `tasks/u4_memory_tasks.yaml` + `tasks/u4_memory/memory.json` | 10 naturalistic tasks + a fixture knowledge-graph seed file for the official `@modelcontextprotocol/server-memory` reference server | |
| | `schemas/tool_schemas.json` | Frozen live tool schemas (name, description, JSON Schema) for all 39 tools across the four real server tiers (14 filesystem + 12 git + 4 sqlite + 9 memory), dumped via `quantmcp dump-schemas`. This is the exact corpus the Schema Complexity Index (SCI) is computed from. | |
|
|
| Every task declares which tool it targets (`tool:` in the YAML — analysis |
| metadata only, never shown to the model) and is naturalistic in its |
| instruction (never names the tool to call), verified against the real |
| server's actual response before being trusted — see the GitHub repo's |
| `docs/RUN_REAL.md` for the full methodology and honesty caveats, including |
| the one live tool (`read_file`, deprecated in favor of the schema-identical |
| `read_text_file`) deliberately left without a task. |
