Documentation
LaTeX to PDF MCP Server
A remote Model Context Protocol (MCP) server that compiles LaTeX documents into publication-quality PDFs via Tectonic and serves them via Cloudflare R2 CDN.
Features • Quick Start • Client Configuration • Architecture • Deployment
🚀 Key Features
- Blazing-Fast Typesetting: Powered by a statically-linked Tectonic engine (
musl), eliminating bulky TeX Live dependencies and dynamic link issues. - Global CDN Delivery: Direct PDF uploads to Cloudflare R2 with zero egress fees and automated 24-hour lifecycle expiration.
- Autonomous Error Self-Correction: When syntax or rendering errors occur, raw compiler diagnostics are fed back to the LLM agent to automatically correct markup in the loop.
- Universal Multi-Client Support: Out-of-the-box support for Gemini Spark, Claude Desktop / Claude Agent, and ChatGPT (via REST Actions).
- Streamable HTTP & Host Resilience: Built with Starlette and FastMCP, featuring ASGI-level header normalization for reverse proxies like Render and Cloudflare.
