Setup Guide

Step 1: Create a Google Cloud Project

1. Go to Google Cloud Console
2. Click Select a project > New Project
3. Name your project (e.g., google-slides-mcp) > Create

Step 2: Enable APIs

1. Navigate to APIs & Services > Library
2. Search and Enable these 2 APIs:

• Google Slides API
• Google Drive API

Step 3: Create OAuth Credentials

1. Go to APIs & Services > Credentials
2. Click + CREATE CREDENTIALS > OAuth client ID
3. If you haven't configured the consent screen yet:

• Click Configure Consent Screen
• Select External > Create
• Fill in App name (e.g., Slides MCP)
• Add User support email and Developer contact email
• Click Save and Continue through all steps > Back to Dashboard

1. Go back to Credentials > + CREATE CREDENTIALS > OAuth client ID
2. Application type: Desktop app
3. Name it (e.g., Slides MCP Desktop)
4. Click Create
5. Click Download JSON > save as credentials.json

Step 4: Install

git clone https://github.com/ryanvo162/google-slides-mcp.git
cd google-slides-mcp
npm install
npm run build

Step 5: Authorize

Copy your credentials.json (downloaded in Step 3) into the project folder:

cp /path/to/credentials.json .

Run the auth flow:

node dist/index.js auth

A URL will appear in the terminal. Open it in your browser, sign in with your Google account, and grant access. Your token will be saved at ~/.config/google-slides-mcp/token.json.

Note: If you see "This app isn't verified", click Advanced > Go to Slides MCP (unsafe). This is normal for unverified apps.

Step 6: Configure with Claude Code

Open ~/.claude.json and add to the mcpServers section:

{
  "mcpServers": {
    "google-slides": {
      "command": "node",
      "args": ["/full/path/to/google-slides-mcp/dist/index.js"]
    }
  }
}

Replace /full/path/to/ with the actual path on your machine.

macOS example: ``json "args": ["/Users/username/google-slides-mcp/dist/index.js"] ``

Windows example: ``json "args": ["C:\\Users\\username\\google-slides-mcp\\dist\\index.js"] ``

Then restart Claude Code to load the MCP server.

Step 7: Test

Open Claude Code and try:

Create a new presentation called "Hello World"

If Claude creates the presentation and returns a Google Slides link, you're all set!

Other MCP Clients

Cursor / Windsurf

Add to .cursor/mcp.json or .windsurf/mcp.json:

{
  "mcpServers": {
    "google-slides": {
      "command": "node",
      "args": ["/path/to/google-slides-mcp/dist/index.js"]
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "google-slides": {
      "command": "node",
      "args": ["/path/to/google-slides-mcp/dist/index.js"]
    }
  }
}

Environment Variables (optional)

| Variable | Description | |----------|-------------| | GOOGLE_CLIENT_ID | OAuth client ID (alternative to credentials.json) | | GOOGLE_CLIENT_SECRET | OAuth client secret | | SERVICE_ACCOUNT_PATH | Path to service account key file | | GOOGLE_IMPERSONATE_USER | Email to impersonate (service account only) | | GOOGLE_MCP_PROFILE | Profile name (supports multiple Google accounts) | | LOG_LEVEL | debug, info, warn, error, silent (default: info) |

Security

• OAuth state parameter for CSRF protection
• Token file stored with permission 0600 (owner-only read)
• Client secret not persisted in token file
• Profile name sanitization (prevents path traversal)
• Minimal OAuth scopes: presentations + drive.file

Tech Stack

• TypeScript + Node.js (ES2022)
• FastMCP — MCP server framework
• googleapis — Google APIs client
• zod — Schema validation

Troubleshooting

"No OAuth credentials found"

Copy credentials.json into the project root. See Step 3 and 5.

"Token might expire"

Run node dist/index.js auth again to re-authorize.

"Google Slides client is not initialized"

Check that credentials.json is valid and Google Slides API is enabled (Step 2).

Claude Code doesn't show the tools

Verify the path in ~/.claude.json is correct. Restart Claude Code after updating the config.
