Which integrations are available for this server?

Provides LaTeX document workflows: search a template library, create projects from templates or LaTeX files, read and edit project documents, compile with pdflatex/xelatex/lualatex, and return compile errors by file and line.

How do I use letX MCP Server?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@letX MCP Server find a thesis template, create a project from it, and compile it" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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.

`get_template`	Details of one template: description, author, license, page link	No
`search`, `fetch`	The same template search and details, in the shape deep research expects	No
`list_projects`	Your letX projects, with their ids	No
`list_project_files`	The documents and uploaded files in one project	No
`read_project_file`	The text of one document in a project	No
`create_project`	A new project from LaTeX files	Creates a project
`create_project_from_template`	A new project from a template	Creates a project
`update_project_file`	Create or replace one document; the previous version stays in the project's history	Replaces a file
`compile_latex`	Compile LaTeX from the conversation in your "AI Scratchpad" project	Replaces that project's files of the same name
`compile_project`	Compile one of your projects	Starts a build
`set_project_compiler`	Set a project's TeX engine: pdflatex, xelatex or lualatex	Changes one setting

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/.
