Getting Started

Get VibeMCP running in under 5 minutes.

Prerequisites

• Node.js 18+ - Download
• Google OAuth credentials (for Gmail/Calendar) - Setup guide
• Microsoft App Registration (for Outlook/Calendar) - Setup guide

You only need one provider. Set up whichever you use.

Step 1: Add VibeMCP to Your AI Client

Claude Desktop

Add to your Claude Desktop config file:

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

{
  "mcpServers": {
    "vibemcp": {
      "command": "npx",
      "args": ["-y", "@vibetensor/vibemcp"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-google-client-id.apps.googleusercontent.com",
        "GOOGLE_CLIENT_SECRET": "your-google-client-secret",
        "MICROSOFT_CLIENT_ID": "your-azure-client-id",
        "MICROSOFT_TENANT_ID": "common"
      }
    }
  }
}

Claude Code

Add to ~/.claude.json under mcpServers:

{
  "mcpServers": {
    "vibemcp": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@vibetensor/vibemcp"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-google-client-id.apps.googleusercontent.com",
        "GOOGLE_CLIENT_SECRET": "your-google-client-secret",
        "MICROSOFT_CLIENT_ID": "your-azure-client-id",
        "MICROSOFT_TENANT_ID": "common"
      }
    }
  }
}

From Source

git clone https://github.com/VibeTensor/vibemcp.git
cd vibemcp
npm install && npm run build

Then use the built files in your MCP config:

{
  "mcpServers": {
    "vibemcp": {
      "type": "stdio",
      "command": "node",
      "args": ["/absolute/path/to/vibemcp/dist/cli.js"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-google-client-id",
        "GOOGLE_CLIENT_SECRET": "your-google-client-secret"
      }
    }
  }
}

Environment Variables

Credentials can also be provided via a .env file in your working directory or in ~/.vibemcp/.env. The MCP client env block is the easiest approach with no files to manage.

Step 2: Restart Your AI Client

After saving the config, restart Claude Desktop or Claude Code so it picks up the new MCP server.

Step 3: Authenticate Your Accounts

Google Account

Through your AI assistant:

You: "Add my Google account user@gmail.com"

VibeMCP will:

1. Open your browser to the Google consent screen
2. You sign in and grant access
3. Your AI calls complete_google_auth to finish

Or via CLI:

npx @vibetensor/vibemcp auth google user@gmail.com

Microsoft Account

You: "Add my Microsoft account user@outlook.com"

VibeMCP will:

1. Show a device code (e.g., ABCD1234)
2. You go to microsoft.com/devicelogin and enter the code
3. Your AI calls complete_microsoft_auth to finish

Or via CLI:

npx @vibetensor/vibemcp auth microsoft user@outlook.com

Verify Accounts

npx @vibetensor/vibemcp accounts list

Or through your AI:

You: "List my connected accounts"

Step 4: Start Using It

Once authenticated, just talk naturally:

You: "Show my latest emails"
You: "Search for emails from john@example.com"
You: "Send an email to jane@company.com about the project update"
You: "What's on my calendar this week?"
You: "Create a meeting with the team on Friday at 2pm"
You: "Show my unified inbox across all accounts"

VibeMCP returns TOON-formatted output by default:

messages[10]{id,subject,from,date,snippet}
19485abc	Team standup notes	alice@company.com	2026-02-16	Here are the notes from...
28ef9d01	Invoice #4521	billing@vendor.com	2026-02-15	Your February invoice...

Your AI reads this format naturally. Switch to JSON anytime by asking:

You: "Show my latest emails in JSON format"

Google Cloud Setup

1. Go to Google Cloud Console > Credentials
2. Create a new OAuth 2.0 Client ID (Application type: Desktop)
3. Add http://localhost:4100/code as an authorized redirect URI
4. Enable the Gmail API and Google Calendar API in your project
5. Copy the Client ID and Client Secret into your MCP config

OAuth Consent Screen

If your app is in "Testing" mode, only test users you've added can authenticate. Add your email as a test user in the OAuth consent screen settings.

Microsoft Azure Setup

1. Go to Azure Portal > App Registrations
2. Register a new application (any name, e.g., "VibeMCP")
3. Set Supported account types to include the account types you need:
   • "Personal Microsoft accounts only" for hotmail/outlook/live
   • "Accounts in any org directory + personal" for both work and personal
4. Under Authentication, enable "Allow public client flows" (required for Device Code)
5. Copy the Application (client) ID into your MCP config

No Redirect URI Needed

Microsoft uses Device Code Flow, so no redirect URI configuration is needed. This is why it works perfectly in CLI environments.

Where VibeMCP Stores Data

All data is stored in ~/.vibemcp/:

File	Purpose
~/.vibemcp/accounts.json	Registry of connected accounts
~/.vibemcp/.oauth2.{email}.json	Google OAuth tokens per account
~/.vibemcp/ms-token-cache.json	Microsoft MSAL token cache

These files contain sensitive credentials. They are stored in your home directory and should never be committed to git.

Troubleshooting

"No accounts connected"

Run list_accounts or accounts_status to check your accounts. You need to authenticate at least one Google or Microsoft account first.

Google OAuth Fails

• Ensure http://localhost:4100/code is listed as an authorized redirect URI in your Google Cloud Console
• Verify Gmail API and Google Calendar API are enabled in your project
• Check that GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET are set correctly
• If app is in "Testing" mode, add your email as a test user

Microsoft Device Code Expires

The device code is valid for ~15 minutes. If it expires, run add_microsoft_account again for a fresh code.

"AADSTS" Errors (Microsoft)

• Ensure "Allow public client flows" is enabled in Azure Portal > App Registration > Authentication
• For personal accounts (hotmail/outlook/live), set Supported account types to include personal accounts
• If you see AADSTS70016, the device code has expired. Get a new one

Token / Auth Issues

OAuth tokens are stored in ~/.vibemcp/. If authentication seems broken:

# Remove the account and re-authenticate
npx @vibetensor/vibemcp accounts remove user@gmail.com
npx @vibetensor/vibemcp auth google user@gmail.com
