概览

AI 生成的概览

本地 MCP 服务器，内置 100 项系统与硬件工程技能，覆盖需求、接口、预算与验证工作。

可以做什么
  • 清洗、提取并映射电子表格和 PDF 中的需求，派生或比对父级与子级需求
  • 依据 ECSS 版本评审需求、查找冲突，并构建验证矩阵或评估测试结果
  • 评审电气与机械接口，构建带余量的功率与质量预算
  • 评审环境鉴定覆盖情况、FMEA 遗漏项、DO-254 保证证据以及招标符合性矩阵
  • 比较规格书版本，生成变更登记与验证影响
适用场景
适合系统与硬件工程师，让助手在专用本地文件夹中处理需求登记表、接口规格、预算、验证证据和标准评审。
运行要求
通过 uvx 从 arc-engineering-mcp 这个 PyPI 包以 stdio 在本地运行，需要 Python 3.11+ 和 uv。环境变量 ARC_ENGINEERING_WORKSPACE 必须指向一个已存在的专用文件夹，用于存放输入和输出。无需模型 API 密钥。
安装前请注意
服务器会读写所配置工作区文件夹中的文件，应指向专用目录而非主目录。对话内容仍会由你的 AI 服务商处理，ChatGPT 上传遵循该服务的政策。ECSS 等标准未随附，需自行提供授权副本。工程修改仅为供审阅的建议，助手本身可能产生费用。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Arc Skills，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

🚀 Get started

Download this repo using Code → Download ZIP. Open the unzipped folder in Codex, or attach the ZIP to a ChatGPT conversation that supports file analysis.

Copy and paste this setup prompt:

text
Set up Arc Skills from:https://github.com/ArcHelps/systems-engineering-skillsUse the repository or ZIP I provided, or fetch the public repository if your tools allow it.Read README.md and docs/SETUP.md, then choose the route this client supports.If you can run local commands, install the locked dependencies, connect the localMCP to Codex using the documented configuration, and check skill discovery.Use a dedicated arc-engineering-work folder for inputs and new outputs.Keep my existing settings and source files intact. Do not publish or upload my files.If you cannot run a local MCP, read the attached catalogue and load only theselected skill and its references for this conversation. Explain any unavailable tools.Show me five relevant skills and run the synthetic requirements example if possible.Say which route actually worked and whether I need to restart or enable anything.
Where you use itWhat works
Codex on your computerLocal MCP with all 100 skills and file tools. Recommended.
ChatGPT webAttached skill instructions + ChatGPT's available file tools. This does not install the MCP.
Claude Desktop / other local MCP clientsThe same local MCP; connection instructions.

Local setup needs Python 3.11+ and uv. No model API key needed.

💬 Try it

Attach a file or place it in your configured work folder, then paste a prompt:

Clean requirements

text
Use Arc Skills to clean and map customer-requirements.xlsx.Preserve every source ID and original statement. Show the field mapping,duplicate IDs, TBDs/TBCs, missing information and unresolved links.Give me a cleaned workbook and an import proposal. Reconcile all row counts.

Review a specification

text
Use Arc Skills to extract and review this requirements PDF.Keep page references, notes, figures and deleted requirements visible.Give me a requirements table and the most consequential issues first:contradictions, broken references, unclear limits and unverifiable statements.Separate confirmed problems from ambiguities. Don't invent missing values.

Review against ECSS

text
Use Arc Skills to review REQ-014 against the ECSS-E-ST-10-06 editionI attached. Cite the inspected criteria, explain each finding and proposethe smallest correction. Preserve the original wording beside the proposal.If you cannot inspect the applicable standard, label the review advisory.

Build a power budget

text
Use Arc Skills to build a system power budget from component-loads.xlsx.Separate standby, nominal and peak demand by operating mode. Preserve units,quantities, duty cycles and source values. Show demand against the suppliedpower limits, conversion losses, missing loads and remaining margin.Don't assume every peak load operates simultaneously or invent missing values.

No file yet?

text
Use Arc Skills to review this requirement:"The unit shall provide an appropriate warning quickly."Explain what is missing and propose clearer wording without inventing a latency.

🔒 Your files

The local MCP processes files in your chosen folder without uploading them to an external server. Your assistant and its AI provider still process the content used in the conversation. ChatGPT uploads follow ChatGPT's policies. Data flow →

The skills and code are free under the MIT license. Your AI assistant may have its own charges. Standards are not bundled; provide authorized copies when needed. Engineering edits are proposals for your review, with source wording preserved.
