sy-automl-mcp
v0.4.0 — 标准 MCP server,任意 MCP 兼容客户端可用(不依赖 Claude Code)。 106 tests pass on
:full, 102+2 skip on:latest. Live stdio + http auth e2e verified. CI lint (ruff check) green. Streamable-http Bearer auth available.
将 AutoGluon 的 AutoML 能力封装为 MCP (Model Context Protocol) 服务,让任意 MCP 兼容客户端(Claude Code、Claude Desktop、Cursor、Cline 等)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 (Post-v0.3.0)
Streamable-HTTP Bearer Token Auth
MCP_API_TOKEN gates the streamable-http transport. stdio is completely unaffected.
Set the token:
docker run -e MCP_API_TOKEN=your-secret-token -e MCP_TRANSPORT=http ...Accepted headers:
Authorization: Bearer <token>(case-insensitive scheme),X-API-Key: <token>, or bare<token>inAuthorization.Unset/empty = auth disabled (backward-compatible, fine for trusted/local networks).
Security: timing-safe comparison (
secrets.compare_digest), generic401 {"detail":"Unauthorized"}(no token echo, no missing-vs-wrong distinction),GET /healthexempted as unauthed liveness probe.stdio needs no auth — it is inherently private (single process, no network).
Production guidance: use a long random token (e.g.
openssl rand -hex 32), never hardcode it in source, bind to trusted networks or place behind TLS/reverse-proxy for internet-facing deployments.

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.

快速开始
拉取预构建镜像(推荐)
# Tabular tier(默认,CPU 即可)
docker run -i --rm -v "$PWD/artifacts:/app/artifacts" ghcr.io/noahwang550/sy-automl-mcp:tabular
# Full tier(+ timeseries + multimodal,建议 GPU)
docker run --gpus all -i --rm -v "$PWD/artifacts:/app/artifacts" ghcr.io/noahwang550/sy-automl-mcp:full
v*tag push 会自动触发 GHCR publish workflow(.github/workflows/docker.yml)。标签包括:latest、:tabular、:full、:v0.2.0。
构建
# Tabular tier(默认,体积较小,CPU 即可)
docker build -t sy-automl-mcp .
# Full tier(+ timeseries + multimodal,建议 GPU)
docker build -t sy-automl-mcp:full --build-arg TIER=full .运行
# stdio 模式(本地 Claude Code)
docker run -i --rm -v "$PWD/artifacts:/app/artifacts" sy-automl-mcp
# streamable-http 模式(远程/共享)
docker run --rm -p 8000:8000 \
-e MCP_TRANSPORT=http -e MCP_PORT=8000 \
-v "$PWD/artifacts:/app/artifacts" sy-automl-mcpWindows Git Bash 注意: 使用
docker run -w /app时需要MSYS_NO_PATHCONV=1前缀,否则 Git Bash 会将/app自动转换为 Windows 路径。
在 Claude Code 中注册(stdio)
claude mcp add autogluon -- docker run -i --rm \
-v /absolute/path/to/sy-automl-mcp/artifacts:/app/artifacts \
sy-automl-mcp接入任意 MCP 客户端(最终用户指南)
不依赖 Claude Code。 本服务是标准 MCP server(JSON-RPC over stdio / streamable-http),任何 MCP 兼容客户端都能连:Claude Code、Claude Desktop、Cursor、Cline、Continue、Zed、Goose、VS Code(MCP 扩展),以及自写的
mcpSDK 客户端。Claude Code 只是其中一种。下面以.mcp.json配置为例,其他客户端字段名类似。
模式 A:本地 stdio(个人 / 敏感数据,无需认证)
每个用户在自己机器上配置客户端,由客户端 spawn 一个本地容器:
{
"mcpServers": {
"autogluon": {
"type": "stdio",
"command": "docker",
"args": [
"run", "-i", "--rm",
"-v", "/ABSOLUTE/PATH/artifacts:/app/artifacts",
"ghcr.io/noahwang550/sy-automl-mcp:full"
]
}
}
}要点:
首次会自动
docker pull。仅表格任务用:latest/:tabular(更小、CPU 即可);需时序/多模态用:full。有 GPU 加
"--gpus", "all"到args。用绝对路径挂载
artifacts/(JSON 不做 shell 展开,$PWD不生效);Windows 用正斜杠如C:/Users/you/automl/artifacts。stdio 是私有进程管道,无需认证。
或命令行注册:
claude mcp add autogluon -- docker run -i --rm -v /abs/path/artifacts:/app/artifacts ghcr.io/noahwang550/sy-automl-mcp:full
模式 B:远程 http 共享(多人 / 团队,需认证)
运维方起常驻服务(设一个随机 token 并记下来分发):
TOKEN=$(openssl rand -hex 32)
docker run -d --name automl-mcp --restart unless-stopped \
-p 8000:8000 \
-e MCP_TRANSPORT=http -e MCP_HOST=0.0.0.0 -e MCP_API_TOKEN="$TOKEN" \
-v /ABSOLUTE/PATH/artifacts:/app/artifacts \
--gpus all \
ghcr.io/noahwang550/sy-automl-mcp:full存活探针(免认证):
curl http://host:8000/health→{"status":"ok"}MCP 端点路径:
/mcp(URL 末尾带上)上公网务必套 TLS(Nginx/Caddy 反代 + HTTPS,或放 VPN/内网后),否则 token 明文走线。
用户配置(把 URL + token 发给用户填入自己客户端):
{
"mcpServers": {
"autogluon": {
"type": "http",
"url": "https://your-host/mcp",
"headers": { "Authorization": "Bearer 用户拿到的TOKEN" }
}
}
}token 错/缺 → 工具调用返回 401 {"detail":"Unauthorized"}。
连上后的一次典型流程
连上后用自然语言驱动,客户端会自动调用 24 个工具:
"加载这份购买意向数据并训练一个分类模型"
→ load_dataset(inline CSV 或 URL) → 行列/样本概要
→ train_tabular(target=purchase, time_limit=300) → 立即返回 task_id
→ get_task_status(task_id) 轮询 → status + progress 字段
(progress: 已拟合模型数 / 最新验证分 / recent log)
→ predict_tabular(新样本) → 返回预测
→ 可选: evaluate_tabular / leaderboard_tabular / feature_importance_tabular通用约束:
训练是长任务:
train_*立即返回task_id,需轮询get_task_status;务必设time_limit(软取消靠它)。模式 B 共用同一台服务器的
artifacts/,约定dataset_id/model_id命名避免撞车。

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 模式可通过
MCP_API_TOKEN实现 Bearer 认证;未设置时仍为无认证(仅限可信网络)。stdio 不受影响。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。
