slidev-orchestrator-mcp

MCP (TypeScript) server to orchestrate multiple Slidev presentations:

• list the presentations under a root folder (mainfolder/presentation1, mainfolder/presentation2, ...)

• create a new presentation (scaffold + npm install)

• start / stop / list Slidev dev servers (automatic port allocation)

• target a presentation: the server connects to that presentation's official Slidev MCP (slidev mcp slides.md) and dynamically re-exposes its tools (prefixed slidev_*) via tools/list_changed.

Expected structure

mainfolder/
├── presentation1/
│   ├── slides.md        <- required (this is what identifies a presentation)
│   └── package.json     <- @slidev/cli as a local dependency (recommended)
└── presentation2/
    └── slides.md

Installation

The package is published on npm as slidev-orchestrator-mcp, so no local clone or build is required — just run it with npx.

Root folder configuration

Priority order:

1. CLI argument: --dir /path/to/mainfolder (or -d, or the first positional argument)

2. Environment variable: SLIDEV_PRESENTATIONS_DIR

Optional: SLIDEV_BASE_PORT (default 3030) — first port tried for dev servers.

Integration

Claude Code

claude mcp add slidev-orchestrator -- npx -y slidev-orchestrator-mcp --dir /path/to/mainfolder

or with the environment variable:

claude mcp add slidev-orchestrator -e SLIDEV_PRESENTATIONS_DIR=/path/to/mainfolder -- npx -y slidev-orchestrator-mcp

OpenCode (opencode.json)

{
  "mcp": {
    "slidev-orchestrator": {
      "type": "local",
      "command": ["npx", "-y", "slidev-orchestrator-mcp"],
      "environment": { "SLIDEV_PRESENTATIONS_DIR": "/path/to/mainfolder" }
    }
  }
}

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "slidev-orchestrator": {
      "command": "npx",
      "args": ["-y", "slidev-orchestrator-mcp", "--dir", "/path/to/mainfolder"]
    }
  }
}

Exposed tools

Notes

• Claude Code (>= 2.1.0) and OpenCode support tools/list_changed: after select_presentation, the slidev_* tools appear directly. Claude Desktop ignores it: use call_slidev_tool instead.

• The presentation's local Slidev binary (node_modules/.bin/slidev) is preferred; falls back to npx -y @slidev/cli (the package is named @slidev/cli, not slidev).

• All child processes (dev servers + Slidev MCP) are cleanly killed on shutdown.

Development

To work on the server itself (not just use it):

git clone https://github.com/death-joke/slidev-orchestrator-mcp.git
cd slidev-orchestrator-mcp
npm install
npm run build
node dist/index.js --dir /path/to/mainfolder
