LeafBridge

Edit your real Overleaf projects by talking to Claude or ChatGPT. No copy-paste, no downloading files, and every change lands in Overleaf as a real Git commit.

milatexai.com · Works with Claude and ChatGPT · Open source (AGPL-3.0)

MiLatexAI is a hosted, remote MCP server that connects your AI assistant to your Overleaf projects over Overleaf's own Git integration. Ask "tighten my introduction" or "add a related-work paragraph citing Smith 2021" and the edit is committed and pushed to Overleaf instantly, visible in your project history where you can review the diff or revert it.

The internal Python package is still named leafbridge.

Use it (hosted, recommended)

Nothing to install. In Claude or ChatGPT, add MiLatexAI as a custom connector:

1. Add the connector using the URL https://milatexai.com/mcp.
   • Claude: Settings, Connectors, Add custom connector, paste the URL, sign in.
   • ChatGPT: Settings, Connectors, enable Developer mode, Add custom connector, paste the URL, authorize. Works on ChatGPT including its free plan.
2. Connect a project. Ask the assistant to connect a project (or run start_connect). You get a one-time link to a secure web form where you paste your Overleaf Git token. It never appears in the chat and is encrypted at rest.
3. Talk to your paper. "List my files," "read the methods section," "why won't it compile," "rewrite this paragraph."

Requirement: Overleaf Git integration (a paid Overleaf feature)

MiLatexAI works through Overleaf's Git integration, which is a premium (paid) feature on Overleaf. To use it on your own projects you need one of:

• An Overleaf paid plan (Standard or Professional), or
• A project shared with you from a premium or group/institutional account that includes Git integration.

Quick test: if you can create a Git token under Overleaf, Account Settings, Git Integration, you are good to go. Free-only Overleaf accounts cannot create Git tokens.

You will also need Claude or ChatGPT. Their free tiers work fine.

Pricing

• Free: 1 connected project, 25 write-commits per month, unlimited reads. Runs on spare capacity (best-effort).
• Pro, $4.99/mo: unlimited projects, unlimited write-commits, guaranteed access.

Reads are always free and unlimited. Overleaf's own subscription is separate and billed by Overleaf. Manage billing inside your assistant or at milatexai.com/account.

What it does

Tool	What it does	Write
list_projects, list_files	List your projects, or a project's files	No
read_file, get_sections, read_section	Read files and navigate LaTeX structure	No
check_compile	Build with a bundled LaTeX engine (Tectonic) and report the exact errors	No
get_history	Recent Overleaf commits	No
edit_file, write_file, delete_file, upload_file	Change files, each an immediate Git commit and push	Yes

Only writes count toward the monthly limit; reads are always free. Every write commits and pushes immediately and returns the commit hash, auditable in Overleaf's history. Paths are validated (no traversal), edits require an exact unique match, and the engine always pulls before pushing and never force-pushes.

---

Security and privacy

• Your Overleaf Git token is entered on a secure web form, encrypted at rest, and never written to the chat.
• MiLatexAI touches only the projects you explicitly connect, nothing else in your Overleaf account.
• We do not store your document contents. We keep only your account email, your encrypted token, and a monthly commit counter.
• The full connector is open source (AGPL-3.0), so you can audit exactly what it does.

Self-host

MiLatexAI is AGPL-3.0, so you can run the server yourself.

python -m venv .venv
. .venv/Scripts/activate          # or: source .venv/bin/activate
pip install -r requirements.txt
python -m pytest -q                # test suite

The hosted service runs leafbridge.asgi:app (Streamable HTTP MCP at /mcp) on Azure Container Apps, with WorkOS AuthKit for authentication and Stripe for billing. Self-hosted Overleaf Server Pro is supported via a git_url override on a project. Running a modified version as a network service requires publishing your changes (AGPL).

---

Status

• Live at milatexai.com: hosted multi-user server, WorkOS sign-in, per-user encrypted tokens, server-side compile checks (Tectonic), Stripe billing, and website sign-in for managing your subscription.
• Roadmap: connector-directory listings, multi-file smart edits, team plans.
