What the publisher says
From the Modulor repository's README, as published. We do not edit it. Read it on GitHub
Modulor
Agent-native 的二维绘图 + 三维建模内核。没有 GUI,没有鼠标——JSON 进,几何出。
English: Modulor is an agent-native 2D drafting + 3D modeling kernel —
the geometry layer for the agent era. No GUI: the entire tool is a
self-describing JSON op protocol (77 ops, contract-tested) over a plain-JSON
document format, callable via CLI, JSON-Lines pipe, MCP server or Python.
Parametric recipes, architectural semantics, freeform surfaces, DXF/glTF
interop, a built-in verification loop (measure / validate / render-and-see),
and a conformance checker for the format. Agents read
AGENT_GUIDE.md; the API contract lives in
docs/API.md; the file format spec in
docs/FORMAT.md. Named after Le Corbusier's Modulor —
a universal measure for building, this time for machines.
传统 CAD软件 是为人类的眼睛和手设计的:菜单、视口、 捕捉、快捷键。Agent 调用它们时,要么模拟人类操作,要么穿过厚重的插件层。 Modulor 反过来:把 CAD 的几何核心保留下来,把交互层整个换成 Agent 的母语 ——结构化命令、结构化结果、结构化错误,外加一条"渲染成图、亲眼验证"的反馈回路。

扩展生态:领域能力住扩展包——装上扩展即获得 mech.gear 渐开线齿轮(官方模板); 三十行代码就能写出你自己的扩展,命名空间与 API 法律由机制强制, 见 docs/PLUGINS.md。
身份与治理:项目名/包名/CLI/格式标识已正式冻结; Standard(规格,供第三方实现)与 Core(参考实现,canonical 而非排他)的 边界、semver 与兼容政策、RFC 流程见 GOVERNANCE.md。
标准的两半都已成文并由测试看守:op 协议——docs/API.md (由注册表生成)+ 机器可读契约 docs/api.json,实现与契约 不一致时测试直接失败;文档格式——docs/FORMAT.md 规格
每份示例文档都在 CI 里对着 schema 验证。
- docs/document.schema.json(JSON Schema),
与主流 CAD 的互操作是契约(docs/INTEROP.md): DXF 导出为 R2000 原生对象(ELLIPSE/SPLINE/HATCH/关联 DIMENSION/ BLOCK+INSERT),在 AutoCAD 里直接可编辑;导入保留块结构;每个导出文件 在 CI 里由 ezdxf(DXF)与 ifcopenshell(IFC4)做语义级校验。
("bay3"、"leveltop('L2')"、"gridx('B')");recipeset 把生成 命令存进文档作为设计意图,set_param + regenerate 一条命令全模型 联动重建——"柱距 4m 改 5m,其他保持联动"就是这两个调用
- 参数化(文档 = 数据 + 配方):任何数值字段接受表达式

- 建筑语义:轴网 add_grid(平面出轴线+编号气泡,交点可在表达式中引用)、
(参数变更、实体增删改、体积面积增量),recipe 让设计意图跨方案继承
- 方案迭代:snapshot / restore 快照,diff 对比两个方案

Modulor: common questions
- Is Modulor MCP server safe?
- Mostly: it is graded B (74/100). Read the Modulor safety report
- How do I install Modulor?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does Modulor need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Modulor maintained?
- The last commit was 145 days ago (2026-06-12). The latest release is v0.7.1.
- What can I use instead of Modulor?
- Servers from other publishers that do the same job: Agent-Native Plan MCP server, 3D AI Agent Avatar MCP server and Ts Core MCP server.
- How does Modulor compare with other AI and agents MCP servers?
- safety score 74/100 (higher than 43% of 4,460 AI and agents servers); github stars 1 (more than 50% of 2,711 AI and agents servers); downloads a week 30 (more than 17% of 1,538 AI and agents servers with a package). Full comparison.
