Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@sy-automl-mcpTrain a tabular model on the iris dataset"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
sy-automl-mcp
v0.3.0 — Phase 1 + Phase 2 + Phase 3 all complete. 88 tests pass on
:full(90% coverage), 84+2 skip on:latest. Live stdio MCP e2e verified. CI lint (ruff check) green.
将 AutoGluon 的 AutoML 能力封装为 MCP (Model Context Protocol) 服务,让 AI 助手(如 Claude Code)通过标准 MCP 工具调用完成数据加载、模型训练、预测、评估、模型管理全流程。
运行环境:Docker 优先。 AutoGluon 官方仅支持 Linux/macOS,原生 Windows 下多模态/torch 依赖不稳定。本项目通过 Linux 容器运行 MCP server,宿主为 Windows 时使用 Docker Desktop 即可,无需 WSL2 直装。
What's New in v0.3.0
Engineering round — 3 optional items completed:
CI lint pipeline —
.github/workflows/lint.ymlrunsruff check .on push/PR to master.ruff check .now passes clean.Progress parsing —
tasks/progress.pybest-effort parses AutoGluon task logs into a structured dict (announced_models,models_attempted,latest_score,latest_model,metric,recent_lines), surfaced as aprogressfield onget_task_statusresponses. Never raises on missing/unreadable logs.80% test coverage target met — 90% coverage in
:full(1089 stmts, 109 miss).tests/test_coverage_gaps.pyadds targeted pure-logic branch tests.
Test counts: :latest 84 passed / 2 skipped, :full 88 passed / 0 skipped. Live stdio MCP e2e re-verified with the new progress field.

What's New in v0.2.0
Phase 3 tech-debt — 4 hardening items resolved, all verified against real AutoGluon in :full:
Per-task cancel race fixed —
tasks/registry.py+tasks/manager.pynow use per-task_state_lockwith sticky terminal states (SUCCESS/FAILED/CANCELLED). A cancel that arrives after completion returnsalready_terminalinstead of overwriting the result.LRU model cache —
tools/model_management.pyreplaced its unbounded predictor dict with a thread-safe_ModelLRUCache(OrderedDict + move-to-end + popitem(last=False)). Cap is configurable viaMCP_MODEL_CACHE_MAX(default4).Task retention —
tasks/registry.pyrunssweep()on add/get/list/snapshot/require, evicting terminal tasks older thanMCP_TASK_RETENTION_SECONDS(default86400) or over capMCP_TASK_MAX_RETAINED(default100). Running/pending tasks are never evicted; evicted-id lookup raises a clear "Task expired or not found".Thread-safe stdout redirect —
tools/_common.pyinstalls a process-wide_ThreadLocalOutputProxyonsys.stdout/sys.stderr._suppress_output()and the background worker set thread-local targets instead of swapping the global stream. Now safe to raiseMCP_MAX_WORKERSabove1for parallel training.
Plus: registry lock upgraded to RLock (sweep() re-enters the store lock), CANCELLED-before-execution now sets finished_at, _ThreadLocalOutputProxy gained explicit __iter__/__next__, and a new live harness e2e_stdio.py drives a real stdio MCP round-trip via the mcp SDK.
Hardening Round (2026-07-09)
Post-v0.2.0 fixes from e2e-runner (AutoGluon 1.5.0 API-drift hunt) and code-reviewer (security/correctness):
AutoGluon 1.5.0 API drift:
TabularPredictor.evaluate()no longer acceptsmetric=— now calls once and filters the returned dict.feature_importance()has noverbosityparam — removed from both calls.Path traversal mitigation:
_resolve_image_path()intools/multimodal.pyconfines image-column values toARTIFACTS_DIR(rejects absolute paths, validates resolved path stays within root).Exception envelope guarantee:
safe_tooldecorator applied to every public tool + defense-in-depth wrapper inserver.py— unhandled exceptions are always converted to the unified{success, data, error}envelope.Traceback leakage removed:
tasks/manager.pyno longer writes full Python tracebacks to user-facing task logs.LRU duplicate-load race resolved:
get_or_load()with per-key lock + double-checked loading replaces the non-atomic check-then-set in_load_model.

开发与测试
# 运行测试(pytest 不在生产镜像中,需运行时安装)
docker run --rm --entrypoint sh \
-v "$PWD/artifacts:/app/artifacts" \
sy-automl-mcp \
-c "pip install pytest pytest-asyncio -q && python -m pytest tests/ -v"
# 运行 lint
docker run --rm --entrypoint sh sy-automl-mcp \
-c "pip install ruff -q && ruff check ."
# 或使用 docker compose(需要 compose 中配置 test profile)
docker compose run --rm app pytest注意:
pytest未打入生产镜像以减小体积。测试时需在容器内临时安装,或使用独立的测试镜像。Windows Git Bash 注意:
docker run命令中若使用-w /app等工作目录参数,需加MSYS_NO_PATHCONV=1前缀防止路径被自动转换。
Stdout 污染防护
AutoGluon / PyTorch / Lightning 会向 stdout/stderr 输出进度条和横幅,可能破坏 MCP stdio JSON-RPC 流。本项目采用线程本地代理 + 两层防御:
tools/_common.py— 在 import 时一次性将sys.stdout/sys.stderr替换为进程级的_ThreadLocalOutputProxy。_suppress_output()上下文管理器将当前线程的目标设为os.devnull,仅影响调用线程。tasks/manager.py— 后台 worker 通过set_thread_output_target(task_log_fh)将该 worker 线程的输出重定向到任务日志文件;执行结束后调用reset_thread_output_target()。其他线程不受影响。此外,支持
verbosity参数的 AutoGluon 构造函数/方法均传入verbosity=0。
已验证::full 镜像的 stdio MCP 端到端测试(initialize → load_dataset → train_tabular → poll → predict_tabular)stdout 上仅有合法 JSON-RPC 帧,无 AutoGluon 泄漏,包括在并发 worker 线程下。
线程安全: stdout/stderr 重定向现在是线程安全的(线程本地目标,代理在安装后只读)。可安全提高
MCP_MAX_WORKERS以并行训练。
限制
训练
fit()可能运行很久;cancel_task为软取消(无法硬杀线程),实际中断依赖time_limit,请始终为训练设置合理的time_limit。streamable-http 模式当前无认证,仅限可信网络。
Windows 原生 Python 运行不在支持范围。
安全说明(hardening round): 多模态工具的图像列路径已通过
_resolve_image_path()限制在ARTIFACTS_DIR内(路径穿越缓解)。所有公开工具通过safe_tool装饰器保证统一信封返回(异常不泄漏)。任务日志不再包含完整 Python 回溯(仅异常消息)。LRU 缓存重复加载竞争已通过get_or_load()解决。
