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。

核心能力(77 个自描述操作,接口已冻结于 1.0-rc)

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

标高 addlevel、房间 addroom(平面自动标注名称+面积 m²)、 面积报告 program(按名称/标高/类型汇总)、坡屋顶 addroof(平/单坡/双坡)、 楼梯 addstair(自动按舒适度公式 2R+T=630 排踏步)、幕墙 add_facade

  • 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.
