What is ShareLatexMCP CLAUDE.md?

Instructions for a local ShareLaTeX connector that works with ShareLaTeX at TUM, a self-hosted version of the collaborative LaTeX editor Overleaf. MCP is a standard way for an agent to call external tools.

Helping an agent inspect ShareLaTeX projects, parse their document structure, and apply section-level or whole-file changes.

It explains how the connector reads project files, understands LaTeX structure, and sends edits through the project’s Git connection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02225	$0.02225
Opus 5	$0.01112	$0.01112
Sonnet 5	$0.00445	$0.00445
Haiku 4.5	$0.00222	$0.00222

Security

Grade A, and why

ShareLatexMCP CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

sharelatex-mcp-server.js is a single-file MCP (Model Context Protocol) stdio server. It gives MCP clients (Claude Desktop, etc.) tools to read ShareLaTeX project files, parse LaTeX document structure, and push section-level or whole-file edits back via the instance's Git integration.

It targets ShareLaTeX @ TUM (sharelatex.tum.de) by default — a self-hosted Overleaf Server Pro deployment. This repo is a fork of mjyoo2/OverleafMCP, which targets overleaf.com; the load-bearing difference is the Git URL shape, https://<host>/git/<projectId> instead of https://git.overleaf.com/<projectId>.

It is not published to npm. Installs go through npx -y github:vinconig/ShareLatexMCP, which is why package.json must keep exactly one bin entry (sharelatex-mcp) and the script must keep its #!/usr/bin/env node shebang and executable bit.

There is no build step and no test suite — the entire runtime is the one script.

Commands

npm install                    # install deps (only @modelcontextprotocol/sdk)
npm start                      # node sharelatex-mcp-server.js

# Smoke-test the MCP protocol directly over stdio (no Claude Desktop needed)
SHARELATEX_PROJECT_ID=... SHARELATEX_GIT_TOKEN=... node sharelatex-mcp-server.js
# → should print "ShareLaTeX MCP server running on stdio" to stderr, then block on stdin

# Local iteration against Claude Desktop: point its config at the cloned script
# (see README "Local Development" for the full JSON snippets)

There are no lint/test scripts defined in package.json. See the README's "Smoke-test the MCP protocol from the shell" section for a one-liner that drives a real tools/call end to end.

Architecture

Everything lives in sharelatex-mcp-server.js, organized top to bottom as:

Config loading (loadProjectsConfig and helpers) — resolves which project(s) to talk to. Priority order, first match wins:
1. SHARELATEX_PROJECT_ID + (SHARELATEX_GIT_TOKEN or SHARELATEX_GIT_TOKEN_FILE) → synthesized as a single project keyed default.
2. SHARELATEX_PROJECTS_CONFIG=/path/to/projects.json (explicit path; missing/invalid file is fatal, no silent fallthrough).
3. projects.json in the OS user config dir (%APPDATA%\sharelatex-mcp on Windows, $XDG_CONFIG_HOME/sharelatex-mcp or ~/.config/sharelatex-mcp elsewhere).
4. ./projects.json (cwd).
5. projects.json next to the script (legacy, for clone-based installs).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
