app.letx由 letx.app 发布官方发布者v1.1.1更新于 Oct 29, 2026

Collaborative LaTeX editor: search 1000+ templates, edit projects, and compile them to PDF.

已验证Streamable HTTP可网页运行效率与工作流文件与存储开发者工具

概览

AI 生成的概览

将 AI 助手连接到 letX 账户，用于查找 LaTeX 模板、创建和编辑项目，并编译成 PDF。

可以做什么
  • 搜索并查看 LaTeX 模板详情，另提供适配深度研究的 search 与 fetch 工具
  • 列出项目及其文件，并读取项目中某个文档的文本
  • 用 LaTeX 文件或模板创建新项目
  • 新建或替换项目文档，旧版本保留在项目历史中
  • 编译对话中的 LaTeX 或已有项目，并设置 TeX 引擎（pdflatex、xelatex、lualatex）
  • 按文件和行号报告编译错误，便于助手修正
适用场景
适合在 letX 中撰写或维护 LaTeX 文档、希望助手在对话里起草、修改并编译的用户，也适合直接从模板开始新的论文、报告或简历项目。
运行要求
需要 letX 账户，首次连接时在浏览器中通过 OAuth 2.1 登录并授权。通过 streamable HTTP 访问远程端点，无需本地运行时或环境变量。在 AI 应用中使用 letX 属于付费方案，Claude 中免费账户可自首次连接起试用 7 天。
安装前请注意
助手可以创建项目、替换项目文件并启动构建，对现有文档的修改应加以核对；被替换的文件仍保留在项目历史中。编译结果包含日志错误和有效期一小时的 PDF 链接。文件内容、项目 ID 等工具参数会发送给 letX，但对话内容本身不会。可在“设置—已连接应用”中随时断开。

安装

在 SourceWeft 中

  1. 打开 控制台中的 LetX，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/app.letx%2Fletx/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

letX

letX is a collaborative LaTeX editor. This plugin connects your AI assistant to your letX account, so you can work on LaTeX documents from the conversation: find a template, start a project, read and edit its files, and compile it to PDF, with the LaTeX errors reported by file and line so they can be fixed.

What it includes

  • The letX MCP server at https://api.letx.app/mcp. You sign in with your letX account (OAuth 2.1) and approve what the assistant may do: read letX's templates, read and edit your projects, and compile them. You can disconnect it at any time in letX under Settings, Connected apps.
  • Two skills:
    • compile-and-fix: compile LaTeX from the conversation or a letX project, and fix the errors it reports until the document builds.
    • start-from-template: find a template in letX's library and start a project from it.

Connect from other MCP clients

The server is also in the MCP Registry as app.letx/letx. Any client can reach it at https://api.letx.app/mcp (streamable HTTP). The first connection opens letX in your browser to sign in and approve access.

  • Claude Code: claude mcp add --transport http letx https://api.letx.app/mcp
  • Codex CLI: codex mcp add letx --url https://api.letx.app/mcp, then approve in the browser tab it opens. If Codex later says it is not signed in, run codex mcp login letx.
  • Other clients that support remote MCP servers with OAuth: add https://api.letx.app/mcp as a remote server in their MCP settings.

What it sends and receives

The plugin runs no code on your machine and connects to nothing but the letX MCP server above. When the assistant calls a tool, letX receives that call's arguments (for example the file it writes or the project it compiles) and returns the result: project names and ids, file lists, the text of the files it reads, template details, compile results with the errors from the log, and a link that opens the PDF for an hour. letX does not receive your conversation. The details are in the privacy policy.

Requirements

A letX account. Using letX from an AI app is part of letX's paid plans, and in Claude a free account can try it for 7 days from its first connection. Plans are described at https://letx.app/pricing/.
