Overleaf MCP server

Overleaf MCP Server

<!-- mcp-name: io.github.YounesBensafia/overleaf-mcp-server -->

An MCP server for managing Overleaf projects through Git synchronization.

PyPI Package · MCP Registry

What This Server Does

• Connects MCP-compatible clients to your Overleaf project through Git sync.
• Exposes file-level tools to list, read, write, and sync project content.
• Keeps workflow simple: pull latest files, edit, then push back to Overleaf.

Requirements

• Python 3.13+
• uv package manager
• An Overleaf plan with Git integration (individual, group, or institution license). Check if your institution provides free access at Overleaf for Institutions - use your institutional email. If your institution is not listed, upgrade your plan.

Git Setup

1. Enable Git - open your project on Overleaf → Menu → enable Git under Integrations.
2. Copy project ID - from the browser URL (e.g. https://www.overleaf.com/project/69a4f7cc4eaf13bd56de5b04 → 69a4f7cc4eaf13bd56de5b04).
3. Generate a Git token - Account Settings → Git integration authentication tokens → Generate new token.
4. Configure .env - copy .env.example to .env and fill in:

OVERLEAF_TOKEN=your_git_token
PROJECT_ID=your_project_id

projectid can also be passed per tool call, but PROJECTID is still required

by the server configuration.

The Overleaf Git token is account-wide credential material. Store it only in the MCP client's environment or a protected .env file, and rotate it if it is exposed.

Safety Notes

Files in an Overleaf project are untrusted input. A .tex file or project configuration can contain instructions aimed at the model; treat file contents as data, not as commands. Keep OVERLEAFALLOWEDPROJECTS restricted to the projects the server should be able to access:

OVERLEAF_ALLOWED_PROJECTS=project_id_a,project_id_b

The default allowlist contains only PROJECT_ID.

Quick Start

git clone https://github.com/younesbensafia/overleaf-mcp-server.git
cd overleaf-mcp-server
uv sync
cp .env.example .env   # then edit with your token/project id
uv run overleaf-mcp

Without a checkout, run the Git version directly with:

uvx --from git+https://github.com/younesbensafia/overleaf-mcp-server overleaf-mcp

Plain uvx overleaf-mcp is appropriate only after the project is published to PyPI.

The server listens on stdio - connect your MCP client (Claude Desktop, etc.) to it.
