The Problem: Your AI is Blind to Your Real Life
You use Claude every day. It's incredibly useful. But there's an absurd problem: Claude knows nothing about you.
It doesn't see your calendar. It can't access your emails. It doesn't read your notes. It doesn't touch your files.
It's like having a brilliant assistant in a windowless room. They can think, but they can't act. They can't contextualize. They can't really help you.
So you do what you always do: copy and paste information.
"Wait, let me copy my agenda for today." "Hold on, I need to find that email." "I have to open my notes file."
It's inefficient. It's repetitive. It's the opposite of automation.
What Are MCPs (Model Context Protocol)
MCPs are bidirectional connections between Claude and your tools. They're not plugins. They're not complicated integrations.
They're simple bridges that give Claude access to:
- Your calendar (Google Calendar, Outlook)
- Your email (Gmail, Outlook)
- Your notes (Notion, Apple Notes)
- Your files (Google Drive, Dropbox, your local system)
- Your databases
- Your custom APIs
The magic is that Claude can read this information and act on it. It can create events, send emails, save notes, create documents.
All from a natural conversation.
Why This Changes Everything
Until now, AI assistants were generic. Useful, yes, but generic.
With MCP, your assistant becomes your assistant. It knows where you are. It knows what you need to do. It knows what you've written before.
It's the difference between a translator who doesn't know you and someone who's worked with you for years.
How to Start: A Real Example
I'll show you how to connect your calendar and email to Claude using MCP. This is what I do in my daily setup.
Step 1: Install Claude Desktop
First you need Claude Desktop (not the web version). Download it from [claude.ai](https://claude.ai).
Step 2: Configure Your First MCP
MCPs are configured in a `claude_desktop_config.json` file. On macOS it's at:
``` ~/.claude/claude_desktop_config.json ```
On Windows:
``` %APPDATA%\Claude\claude_desktop_config.json ```
Step 3: Practical Example - Google Calendar
Here's the configuration to connect Google Calendar:
```json { "mcpServers": { "google-calendar": { "command": "npx", "args": [ "-y", "@anthropic-ai/mcp-server-google-calendar" ], "env": { "GOOGLE_CALENDAR_CREDENTIALS": "/path/to/your/credentials.json" } } } } ```
Then, in Claude Desktop, simply ask:
"What do I have on my calendar for tomorrow?"
Claude will access your calendar, read your events, and tell you. No copy and paste. No leaving the conversation.
Step 4: Add Email (Gmail)
Same process. Add another MCP server:
```json { "mcpServers": { "google-calendar": { ... }, "gmail": { "command": "npx", "args": [ "-y", "@anthropic-ai/mcp-server-gmail" ], "env": { "GMAIL_CREDENTIALS": "/path/to/your/gmail-credentials.json" } } } } ```
Now you can ask:
"Do I have any important emails from my boss? If it's urgent, create an event on my calendar."
Claude reads your emails, evaluates, and if necessary, creates the event automatically.
Real Use Cases
This isn't theory. This is what I do daily:
1. Weekly Planning
"Review my calendar and project notes. What should I focus on this week given what I have scheduled?"
Claude sees your meetings, reads your project notes, and gives you contextualized prioritization.
2. Smart Email Responses
"I have 15 unread emails. Which ones need urgent replies? For the others, delete the newsletters."
Claude filters, categorizes, and can even help you draft responses based on your notes context.
3. Idea Capture
"I just had a product idea. Save it to my Notion base with this structure: name, 2-line description, why it's viable."
Claude takes the idea, structures it, and saves it directly.
4. Context Synthesis
"I have a meeting in 30 minutes with client X. Give me a summary of:
- What emails we've exchanged
- What notes I have about them
- What's on my calendar related to them."
All in one conversation. Without opening 5 tabs.
The Technical Side (For Developers)
If you're a developer, you can create your own MCPs. The architecture is simple:
1. Your MCP server exposes tools 2. Claude calls them when needed 3. Your server executes the logic and returns results
Minimal example in Node.js:
```javascript const { Server } = require('@anthropic-ai/sdk');
const server = new Server({ name: 'my-assistant', version: '1.0.0', });
server.setRequestHandler(CallToolRequestSchema, async (request) => { if (request.params.name === 'get_calendar_events') { // Your logic here const events = await fetchCalendarEvents(); return { content: [{ type: 'text', text: JSON.stringify(events) }] }; } }); ```
You can connect databases, custom APIs, webhooks. The possibilities are endless.
Honest Limitations
Not everything is perfect:
- **Authentication**: Setting up credentials can be tedious the first time
- **Privacy**: You're sharing access to sensitive data. Make sure you trust the MCP server
- **Latency**: Accessing external services adds milliseconds
- **Permissions**: Some services (Gmail, Calendar) require OAuth approval
But once configured, it works. And it works well.
Why This Matters Now
We're in a strange moment with AI. Everyone talks about "agents" and "automation", but most AI tools are still passive.
MCP is different. It's the first real step toward assistants that understand your specific context.
It's not generic AI. It's personalized AI.
And that changes everything.
Next Step
If you want to experiment:
1. Download Claude Desktop 2. Configure a simple MCP (Google Calendar is easiest) 3. Ask something that requires that context 4. Watch it work
Then build from there. Add email. Add notes. Create your own MCP for your specific tools.
The line between "tool" and "assistant" is disappearing. And those who start now have an advantage.
