Description

🤖 MCP Personal Assistant Workflow Description

This workflow integrates multiple productivity tools into a single AI-powered assistant using n8n, acting as a centralized control hub to receive and execute tasks across Google Calendar, Gmail, Google Drive, LinkedIn, Twitter, and more.

✅ Key Capabilities

AI Agent + Tool Use**: Built using n8n's AI Agent and MCP system, enabling intelligent multi-step reasoning.
Tool Integration**:
Google Calendar: schedule, update, delete events
Gmail: search, draft, send emails
Google Drive: manage files and folders
LinkedIn & Twitter: post updates, send DMs
Utility tools: fetch date/time, search URLs
Discord Input**: Accepts prompts via n8n_discord_trigger_bot repo link

🛠 Setup Instructions

Timezone Configuration:
Go to Settings > Default Timezone in n8n.
Set to your local timezone (e.g., Asia/Jakarta).
Ensure all Date & Time nodes explicitly use the same zone to avoid UTC-related bugs.

Tool Authentication:
Replace all OAuth credentials for:
Gmail
Google Drive
Google Calendar
Twitter
LinkedIn
Use your own accounts when copying this workflow.

Platform Adaptability:
While designed for Discord, you can replace the Discord trigger with any other chat or webhook service.
Example: Telegram, Slack, WhatsApp Webhook, n8n Form Trigger, etc.

📦 Strengths

Great for document retrieval, email summarization, calendar scheduling, and social posting.
Reduces the need for tab-switching across multiple platforms.
Tested with a comprehensive checklist across categories like:
Calendar
Gmail
Google Drive
Twitter
LinkedIn
Utility tools
Cross-tool actions
(Refer to discordGPT prompt checklist for prompt coverage.)

⚠️ Limitations

❌ Binary Uploads:
AI agents & MCP server currently struggle with binary payloads.
Uploading files to Gmail, Google Drive, or LinkedIn may fail due to format serialization issues.
Binary operations (upload/post) are under development and will be fixed in future iterations.

❌ Date Bugs:
If timezone settings are incorrect, event times may default to UTC, leading to misaligned calendar events.

🔬 Testing

Use the provided prompt checklist for full coverage of:
✅ Core feature flows
✅ Edge cases (e.g., invalid dates, nonexistent users)
✅ Cross-tool chains (e.g., Google Drive → Gmail → LinkedIn)
