2slides MCP Server

Expose 2slides.com tools to MCP clients: generate PowerPoint decks

and custom-designed slides, add AI voice narration, and get the finished files back as

download links.

Get Your API Key

Before connecting, get an API key from 2slides.com/api.

Connect

2slides runs a hosted Streamable HTTP MCP endpoint, and also ships this stdio

package. Both expose the same 7 tools against the same account and the same credits.

Option 1 — Streamable HTTP (recommended)

Anthropic's MCP docs call HTTP "the recommended option for connecting to remote MCP

servers", and 2slides is a hosted service with no local files or processes to reach, so

start here.

Claude Code

claude mcp add --transport http 2slides "https://2slides.com/api/mcp?apikey=YOUR_2SLIDES_API_KEY"

Verify with `claude mcp list` — the server should report `✔ Connected`.

Project config (`.mcp.json`, shared with your team)

{
  "mcpServers": {
    "2slides": {
      "type": "http",
      "url": "https://2slides.com/api/mcp?apikey=YOUR_2SLIDES_API_KEY"
    }
  }
}

Claude Desktop / claude.ai: add it as a custom connector at

claude.ai/customize/connectors with the same

URL.

Option 2 — stdio (local process)

Use this when the client can only spawn local processes, when the machine has no direct

route to 2slides.com, or when you want to pin and patch the server yourself.

Claude Code

claude mcp add 2slides -e API_KEY=YOUR_2SLIDES_API_KEY -- npx -y 2slides-mcp@latest

Claude Desktop — edit `~/Library/Application Support/Claude/claude_desktop_config.json`

(`%APPDATA%\Claude\claude_desktop_config.json` on Windows):

{
  "mcpServers": {
    "2slides": {
      "command": "npx",
      "args": ["-y", "2slides-mcp@latest"],
      "env": {
        "API_KEY": "YOUR_2SLIDES_API_KEY"
      }
    }
  }
}

The `-y` flag lets npx install the package without prompting. Fully restart Claude Desktop

afterwards; in a chat, open the tools panel and you should see the tools below.

Typical Workflows

Fast PPT (theme-based PowerPoint):

1. `themes_search` → get a `themeId`

2. `slides_generate` (sync) → get `downloadUrl` directly

Nano Banana (custom-designed slides):

1. `slides_create_like_this` or `slides_create_pdf_slides` (async) → get `jobId`

2. `jobs_get` (poll every 20s) → get `downloadUrl` when `status: "success"`

Nano Banana with narration:

1. `slides_create_like_this` or `slides_create_pdf_slides` → get `jobId`

2. `jobs_get` → wait for slides to complete

3. `slides_generate_narration` → get narration `jobId`

4. `jobs_get` → wait for narration to complete

5. `slides_download_slides_pages_voices` → get ZIP download link

Troubleshooting (Claude Desktop)

• If tools don't appear in Claude, verify the config path is absolute and restart the app.
• Check Claude MCP logs:

tail -n 50 -f ~/Library/Logs/Claude/mcp*.log

• For stdio MCP servers, avoid logging to stdout; this server only logs errors to stderr.
