unPaper CLI — Watchlist

MCP100 Assessment

Watchlist / Tracking

Why we’re tracking it

Follow-up value is specific to unPaper local deck validation and PowerPoint conversion: Do rendered measurements preserve editable slide output while MCP template execution remains explicitly client-owned?

Reviewed Oct 5, 2026 · Documentation review; complete setup workflow not independently tested

Best fit

Generate and validate editable PowerPoint files offline from HTML slide decks.

What we know

Slide decks locally: templates, checks, HTML to editable PowerPoint, .pptx rescue. No AI inside. This profile is based on verified official documentation where listed; unresolved operational details are explicitly marked.

All limitations / Review context

Do rendered measurements preserve editable slide output while MCP template execution remains explicitly client-owned?

The bounded review of the publisher's documented unPaper local deck validation and PowerPoint conversion and release notices identified no disclosed material condition preventing an accurately scoped public tracking entry. The resource's operational permissions remain uncertainty; this assessment does not certify installation safety.

Potential high-impact side effects: Write local PPTX output.
Local file input/output
Local CLI operation; no hosted account requirement established
Conversion runs locally according to official publisher description.
Reviewed write actions: Write local PPTX output
Sensitive access: Local slide source, Generated presentations
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
Runtime behavior, dependencies and undisclosed vulnerabilities were not independently audited.
Documented tool authority and any remote data handling must be checked before installation or use.
Tool inventory, client matrix and permissions completeness were not requirements for this Radar tracking review.
repositoryIdentity: no confirmed package-to-repository binding
cost: plans, pay-per-call charges, and payment authorization details
MCP protocol server authenticity / tools-list support
A CLI with MCP-related discoverability, not yet proven to expose a working MCP server
Writes local PowerPoint files
Do not conflate separate @unpaper/unpaper browser product with @unpaper/cli
MCP protocol authenticity is not yet verified; do not market as a confirmed MCP server.

Warning

No third-party MCP installation, execution, connection, payment or mutation performed.
Official documentation may not prove currently operational service.
Do not claim importer is installed solely by MCP registration.
Targeted 2026-10-13 re-research: Publisher explicitly documents npx -y @unpaper/cli mcp, not npx -y @unpaper/cli without subcommand.
Publisher explicitly documents npx -y @unpaper/cli mcp, not npx -y @unpaper/cli without subcommand.
Publisher client example explicitly runs mcp subcommand.
Batch08 V3 source-specific finding: Only published bin metadata independently corroborated; no full README.
CLI package with MCP support; CLI npx invocation alone not verified as MCP stdio registration.
Documentation example; follow publisher prerequisites and confirm host syntax. No execution performed.
Client-specific example. Not interchangeable with VS Code servers or Codex TOML. No runtime test.

Set up testing / debugging integration
Publisher instructions
CLI MCP mode requires mcp subcommand; presentation imports may need LibreOffice and file permissions.
Unpaper provides a local offline CLI and MCP host configuration `npx @unpaper/cli` (MCP entry uses publisher JSON). Not an online authenticated API.

MCP100 setup guide

CLI MCP mode requires mcp subcommand; presentation imports may need LibreOffice and file permissions.

Check connection
Suggested check
Publisher CLI `npx @unpaper/cli check deck.html` checks L0-L3 conformance of an EXISTING local HTML deck; separate from inspecting MCP tool discovery.
Remove / uninstall / revoke
MCP100 setup guide
Generic client guidance (not publisher-specific uninstall): unregister MCP entry in the chosen client. If installed globally, remove the npm package separately. Revoke provider access separately through account controls, where supported. This does not erase local data or revoke funds/credentials automatically.
Unregister the named MCP entry from the actual host separately from removing a global npm install; no claim that either revokes remote credentials.
Unpaper local offline CLI/MCP uses no provider API key in the publisher documented route; credential revocation not applicable.
