Limitations

Slidev MCP is designed to be simple and secure. Some Slidev features are not available in the current version.

Images

Image source	Supported?	Notes
Remote URLs ()	Yes	Browser fetches the image when viewing the slides
Base64 inline ()	Yes	Works but inflates markdown size (1 MB limit)
Local file paths ()	No	No mechanism to upload files to the builder

Recommendation: Use remote image URLs. If you need to embed an image without hosting it, use base64 encoding.

Features Not Available

Feature	Why	Workaround
Live preview	Each change requires a full build (7-30s)	Iterate by asking your assistant to update specific slides
Presenter mode	Not included in the static build	View slides directly in the browser
Custom CSS/JS files	No file upload support	Use inline <style> and <script setup> blocks in markdown
Custom fonts	No file upload support	Use web fonts via URL imports in <style> blocks

Export

PDF export and slide screenshots are fully supported:

Feature	Tool	Notes
PDF export	export_slides	Server-side Playwright rendering; returns a download URL
Slide screenshots	screenshot_slides	Returns one PNG per slide for visual review

Both tools take the UUID of the presentation.

Limits

Limit	Default	Description
Markdown size	1 MB	Maximum size of the markdown input
Build timeout	120 seconds	Maximum time for a single build
Concurrent builds	3	Maximum simultaneous builds on the server
Slide TTL	30 days	Slides are automatically deleted after this period without an update

Access Model

The server has no accounts and no per-connection state, because the current MCP protocol (2026-07-28) is stateless. A presentation's UUID is its only credential:

• Anyone who has the UUID can update, export, or screenshot the presentation. The UUID is part of the slide URL (/slides/{uuid}/), so treat the URL like an edit link: sharing it shares edit access through this server.
• UUIDs are random v4 values and cannot be guessed or listed. The server has no way to enumerate other people's presentations.
• A presentation can be updated from any connection, in any conversation, and across server restarts, for as long as it exists.
• list_session_slides only looks up UUIDs you pass in; keep the UUIDs returned by render_slides.

Theme Set

The available themes are fixed at build time. Each theme is individually curated — license-checked, version-pinned, and build-validated. You cannot install custom themes at runtime. See the full theme list.
