JLCEDA Codex MCP Bridge / 嘉立创 EDA Codex MCP 桥接

中文 | English

中文说明

这是一个面向嘉立创 EDA 专业版（JLCPCB/Lichuang EDA Pro）的本地桥接项目。它包含一个嘉立创 EDA 扩展和一个本地 MCP/HTTP/WebSocket 服务，让 Codex 或其他 MCP 客户端可以自动导出并解析：

• 原理图/PCB DRC 状态
• 原理图/PCB 网表（EasyEDA JSON 或 Protel2）
• BOM（CSV/TSV/XLSX，支持 UTF-16LE/base64）

项目的目标不是替代嘉立创 EDA，而是把 GUI 内部的检查和制造数据变成可程序化读取的 JSON，方便后续做自动诊断、网表查询、BOM 检查和闭环修改。

功能

• 嘉立创 EDA 顶部菜单：CodexExport044
• Live WebSocket 桥接：Codex 可主动请求当前打开工程导出 JSON
• 一次性 HTTP 导出：扩展可把 JSON 推送到本地服务
• MCP 工具：列出导出、请求导出、读取摘要、查询网络、查询器件、解析 BOM、输出诊断
• DRC API 调用错误和真实 DRC 条目分离，避免把“当前没有 PCB 画布”误判为设计规则错误
• 保留原始导出数据，同时提供结构化摘要

.\scripts\start-local-bridge.ps1

健康检查：

Invoke-WebRequest -UseBasicParsing http://127.0.0.1:38425/health
Invoke-WebRequest -UseBasicParsing http://127.0.0.1:38425/api/jlceda/ws-status

打包嘉立创 EDA 扩展

npm run package:extension

生成 .eext 后，在嘉立创 EDA 专业版的扩展管理器中导入。导入并重启嘉立创 EDA 后，打开工程，在顶部菜单点击：

CodexExport044 -> Start Live Bridge

连接成功后，Codex/MCP 客户端就可以主动请求导出。

MCP 配置示例

在支持 MCP 的客户端中配置本地 server。把 <repo> 替换为本仓库路径：

{
  "mcpServers": {
    "jlceda-codex": {
      "command": "node",
      "args": [
        "<repo>\\mcp\\server.js"
      ],
      "env": {
        "JLCEDA_EXPORT_DIR": "<repo>\\exports",
        "JLCEDA_MCP_HTTP_PORT": "38425",
        "JLCEDA_MCP_WS_PORT": "38426"
      }
    }
  }
}

Codex config.toml 示例：

[mcp_servers.jlceda_codex]
command = "node"
args = ['<repo>\mcp\server.js']
startup_timeout_sec = 30

[mcp_servers.jlceda_codex.env]
JLCEDA_EXPORT_DIR = '<repo>\exports'
JLCEDA_MCP_HTTP_PORT = "38425"
JLCEDA_MCP_WS_PORT = "38426"

MCP 工具

• jlceda_list_exports：列出收到的 JSON 导出文件
• jlceda_bridge_status：查看 live WebSocket 连接状态
• jlceda_request_export：请求嘉立创 EDA 当前工程立即导出
• jlceda_latest_export_summary：摘要最新导出
• jlceda_read_export：读取指定导出 JSON
• jlceda_parse_protel2_netlist：解析 EasyEDA JSON 或 Protel2 网表
• jlceda_find_net：查询网络及其连接管脚
• jlceda_find_component：按位号、值、封装或料号查询器件
• jlceda_diagnostics：输出 DRC 与未连接管脚诊断
• jlceda_bom_rows：解析 BOM 行
• jlceda_export_dir：显示导出目录和端口

验证

npm --prefix mcp run check
npm --prefix mcp run smoke
.\scripts\check-live-bridge.ps1

真实闭环验证流程：

1. 启动本地 bridge。
2. 打开嘉立创 EDA 工程。
3. 点击 CodexExport044 -> Start Live Bridge。
4. 调用 MCP 工具 jlceda_request_export。
5. 用 jlceda_find_net、jlceda_find_component、jlceda_diagnostics 分析导出的 JSON。

隐私与限制

• exports/、logs/、node_modules/ 默认不会进入 git。
• 导出的 JSON 可能包含完整网表、BOM、工程路径或器件信息，公开仓库前请不要提交真实项目导出。
• 嘉立创 EDA 的 SCH_Drc.check 和 PCB_Drc.check 属于 API 中的 BETA 能力，返回结构可能随版本变化。
• 本项目当前实现的是“导出与诊断闭环”的数据通路；自动修改嘉立创工程文件需要额外的编辑策略和复核流程。

English

This project bridges JLCPCB/Lichuang EDA Pro with Codex and other MCP clients. It includes a JLCEDA Pro extension plus a local MCP/HTTP/WebSocket server that can export and parse:

• schematic/PCB DRC status
• schematic/PCB netlists, including EasyEDA JSON and Protel2-style data
• BOM files, including CSV/TSV/XLSX and UTF-16LE/base64 exports

The goal is not to replace JLCEDA Pro. The goal is to turn GUI-only design checks and manufacturing data into structured JSON that can be queried by automation, reviewed by Codex, and used as the data layer for later closed-loop schematic repair.

Features

• JLCEDA Pro top menu: CodexExport044
• Live WebSocket bridge: an MCP client can request an export from the currently open project
• One-shot HTTP export path from the extension to the local receiver
• MCP tools for export listing, live export requests, summaries, net lookup, component lookup, BOM parsing, and diagnostics
• DRC API attempt errors are separated from real rule items, so a missing PCB canvas is not reported as a design-rule violation
• Raw export payloads are preserved while structured summaries are generated

Install

Node.js 20 or newer is required.

npm install
npm --prefix mcp install

Start The Local Bridge

Development mode:

npm --prefix mcp run http

Hidden Windows background process:

.\scripts\start-local-bridge.ps1

Health checks:

Invoke-WebRequest -UseBasicParsing http://127.0.0.1:38425/health
Invoke-WebRequest -UseBasicParsing http://127.0.0.1:38425/api/jlceda/ws-status

Package And Install The JLCEDA Extension

npm run package:extension

Import the generated .eext file in the JLCEDA Pro extension manager. Restart JLCEDA Pro, open a project, then click:

CodexExport044 -> Start Live Bridge

After the live bridge is connected, MCP clients can request exports.

MCP Configuration Example

Replace <repo> with the local repository path:

{
  "mcpServers": {
    "jlceda-codex": {
      "command": "node",
      "args": [
        "<repo>\\mcp\\server.js"
      ],
      "env": {
        "JLCEDA_EXPORT_DIR": "<repo>\\exports",
        "JLCEDA_MCP_HTTP_PORT": "38425",
        "JLCEDA_MCP_WS_PORT": "38426"
      }
    }
  }
}

Codex config.toml example:

[mcp_servers.jlceda_codex]
command = "node"
args = ['<repo>\mcp\server.js']
startup_timeout_sec = 30

[mcp_servers.jlceda_codex.env]
JLCEDA_EXPORT_DIR = '<repo>\exports'
JLCEDA_MCP_HTTP_PORT = "38425"
JLCEDA_MCP_WS_PORT = "38426"

MCP Tools

• jlceda_list_exports: list received JSON exports
• jlceda_bridge_status: show live WebSocket status
• jlceda_request_export: request a live export from JLCEDA Pro
• jlceda_latest_export_summary: summarize the newest export
• jlceda_read_export: read a specific export JSON
• jlceda_parse_protel2_netlist: parse EasyEDA JSON or Protel2 netlists
• jlceda_find_net: find a net and connected component pins
• jlceda_find_component: find a component by designator, value, footprint, supplier part, or manufacturer part
• jlceda_diagnostics: return DRC state and unconnected-pin diagnostics
• jlceda_bom_rows: return parsed BOM rows
• jlceda_export_dir: show the active export directory and bridge ports

Validation

npm --prefix mcp run check
npm --prefix mcp run smoke
.\scripts\check-live-bridge.ps1

Real closed-loop test:

1. Start the local bridge.
2. Open a project in JLCEDA Pro.
3. Click CodexExport044 -> Start Live Bridge.
4. Call jlceda_request_export.
5. Use jlceda_find_net, jlceda_find_component, and jlceda_diagnostics to inspect the exported JSON.

Privacy And Limits

• exports/, logs/, and node_modules/ are ignored by git.
• Exported JSON can contain full netlists, BOMs, project paths, and component data. Do not commit real project exports to a public repository.
• JLCEDA SCH_Drc.check and PCB_Drc.check are BETA APIs and their return shape may change.
• This project provides the export and diagnostics data path. Automatic project-file edits require a separate editing strategy and manual review loop.
