Multi-Account Authentication

VibeMCP supports connecting multiple Google and Microsoft accounts simultaneously. This enables cross-account operations like unified inbox and merged calendar views.

Adding Accounts

Multiple Google Accounts

> Add my work Google account (work@company.com)
  → add_google_account
  → complete_google_auth

> Add my personal Google account (me@gmail.com)
  → add_google_account
  → complete_google_auth

Multiple Microsoft Accounts

> Add my work Microsoft account (work@company.com)
  → add_microsoft_account
  → complete_microsoft_auth

> Add my personal Outlook account (me@hotmail.com)
  → add_microsoft_account
  → complete_microsoft_auth

Mixed Providers

You can connect both Google and Microsoft accounts. VibeMCP auto-detects the provider when routing tool calls.

How It Works

• Each account's OAuth tokens are stored separately as .oauth2.{email}.json
• VibeMCP maintains a service cache with 10-minute TTL per account
• Calendar tools auto-detect the provider (Google vs Microsoft) based on the account registry
• Unified tools fan out queries to all connected accounts and merge results
