Presio MCP Server

Presio

Present PDFs from your browser — try it at presio.xyz.

Upload a PDF presentation, get a short link, and control the slideshow from one browser window while viewers watch in another. Presio is a hosted service; this repository is its source code.

Use it from an AI agent

Nothing to install — agents talk to the hosted service directly:

• MCP — connect to https://presio.xyz/mcp (streamable HTTP, no auth). Tools: present_pdf, check_pdf.
  • Claude Code: claude mcp add --transport http presio https://presio.xyz/mcp
  • Claude.ai, ChatGPT, Cursor, …: add a custom connector / MCP server with that URL
• REST — curl -F file=@deck.pdf https://presio.xyz/api/present returns a link; opening it in a browser starts the presentation.
• Agent docs — llms.txt · AGENTS.md · api.md · OpenAPI

Features

• Local by default — your PDF stays in the browser and is never uploaded. Works offline; local presentations are kept for up to 7 days.
• Controller + viewer — drive slides from the controller window while a viewer window mirrors it, kept perfectly in sync.
• Present across devices — log in and sync online to get a 6-character session code. Viewers enter it on the home page and follow along live over WebSockets.
• Shared control — hand out a controller passphrase to let someone else drive.
• Speaker notes — written next to your current and next slide, rendered as markdown.
• Embedded media — local videos and GIFs, direct video URLs, and YouTube/Vimeo. Playback, autoplay, and seeking all stay in sync with viewers.
• Presentation timer — track how long you've been talking.
• Customizable controller — rearrange the layout and remap keyboard shortcuts.
• Recent presentations — pick up where you left off from the home page.
• Download — anyone can grab the PDF from the presentation view.
• Agent APIs — MCP server and REST API for AI agents; see Use it from an AI agent.

Adding videos and speaker notes

The easiest way to attach videos and speaker notes is the Presio Typst package:

#import "@preview/presio:0.2.1": media, speaker-notes

= Introduction

Hello world.

#speaker-notes[
  Remember to mention the demo before moving on.
]

#media("https://www.youtube.com/watch?v=dQw4w9WgXcQ", width: 60%, aspect-ratio: 16/9)

Presio reads the attached media and notes from the PDF automatically. Notes can also be embedded by hand from plain Typst or LaTeX. See the about page for details.
