The Context switching tax is [toggling between apps 1'200 times](https://hbr.org/2022/08/how-much-time-and-energy-do-we-waste-toggling-between-applications?ref=brianchristner.io) per day. That’s four hours a week — or five weeks a year — wasted just flipping between apps and tabs. This doesn't take into [consideration the amount of time to regain focus for each context switch.](https://brianchristner.io/the-ultimate-productivity-system-from-mindset-to-metrics/)

Modern professionals are overwhelmed by a multitude of tabs, apps, notifications, emails, messages, and more. Take a moment and count how many tabs and apps you currently have open while reading this. I currently have **27 tabs and 12 apps open** while writing this blog post**.** 

What if instead of dozens of apps and tabs pulling at you, you had a single interface to every app you own and use? That’s what I call a Human OS.

I'm currently developing my own Human OS. What is a Human OS, you ask? 

### **Definition: Human OS**

A **Human Operating System** is a unified digital layer (a single interface) that reduces context switching by connecting all your tools, data, and workflows into a single user interface. Instead of adapting to dozens of fragmented apps, your Human OS adapts to you. 

**In practice, the Human OS:**

1. **Centralizes context** – Keeps all your work (projects, data, messages) accessible from one conversational or visual interface in my case Claude Desktop.
2. **Automates orchestration** – Uses AI to coordinate actions across multiple apps without manual switching (app orchestration is the massive unlock).
3. **Personalizes execution** – Learns your patterns, preferences, and priorities so it works the way *you* think.
4. **Frees attention** – Minimizes the constant mental reset that comes with app-hopping, notifications, and tool fragmentation.

### **Key Difference From Just Another Productivity Tool**

- **Not** just another “all-in-one” app.
- **Is** an adaptive layer across everything you already use.
- Built on interoperability (MCP, APIs) and powered by AI to provide continuity.
- Plug in the apps you use via MCP servers, customized to your workflows.

## **Why Current Productivity Stacks Fail**

We’ve tried the single *SaaS that does everything*. **Spoiler: it never does.** Instead, we cobble together a Frankenstein tech stack, stitched from half-solutions and the false hope of more productivity.

The core problem isn’t a lack of tools...it’s interoperability. No single app can be the “top tool.” **What usually ends up dominating? Email and chat.** Not because they’re productive, but because they’re loud...constant pings, endless notifications. 

> **That’s not a strategy. That’s chaos.**

---

## **Enter AI + MCP Servers**

We all know (and some secretly fear) AI by now. But on its own, AI is only half the story. To unlock its full potential, you need [**MCP servers**](https://github.com/punkpeye/awesome-mcp-servers?ref=brianchristner.io)**...**the middleware that connects everything through a standard interface.

Picture this: you prompt your AI with, *“Pull the latest sales numbers, draft an email to my manager with the sales data, and schedule a follow-up meeting.”*

- **AI is the brain:** it interprets your request, plans the steps, and decides which tools to use.
- **MCP is the spine:** it integrates with your CRM for sales data, your email client for message drafting, and your calendar for scheduling meetings.

The result? One instruction/prompt, all the moving parts handled. Your **Human OS** abstracts away the mess so you can focus on the actual work. 

> **No tab-flipping. No context loss.**

## Practical Use Case: The Power of Dual MCP Integration

As you may know, I am an avid [mountain biker,](https://brianchristner.io/mountain-biking-coming-age/) but more importantly, I enjoy reviewing and obsessing over the data from my rides. I want to share my personal MCP use case, which involves using [Strava](https://brianchristner.io/how-to-win-strava-kom-segments/) and Garmin.

![](https://storage.ghost.io/c/29/50/2950930d-60f2-422c-90aa-232fbd4873b6/content/images/2025/09/E4F681A0-FF60-40B2-88D4-1106626CA84F.jpeg)

My latest ride

Most people think of MCP servers as “connectors,” but the real magic happens when you run more than one at a time. Take [**Strava**](https://brianchristner.io/how-to-win-strava-kom-segments/) **\+ Garmin** as an example. Each app has its strengths:

#### **Stay Updated**

Get actionable AI & tech insights delivered every Friday. No fluff, just value.

- **Garmin**: physiological data — sleep quality, HRV, stress, recovery.
- **Strava**: performance and social — segment times, competition, routes, kudos.

**On their own, both are useful. Combined through MCP, they become exponentially more powerful.**

---

Let's take a look at how combining MCPs unlocks a new level of productivity.

### 1\. Recovery vs Performance Correlation

- **Garmin** shows: Body Battery at 88%.
- **Strava** shows: You set a PR on the *local Strava Challenge*.
- **Combined**: If your Body Battery is 80%+, you’re 3x more likely to hit a PR.  
**Insight is only possible through both MCPs.**

---

### 2\. Hidden Training Patterns

- **Garmin** logs a stress spike at 15:00.
- **Strava** shows you were on a brutal 14.4% grade.
- Together, you learn that steep climbs consistently trigger disproportionate stress responses. Now you can train specifically for that weakness.

---

### 3\. Sleep Impact on Segments

Garmin says you got only 10% REM. Strava shows your time dropped by 12%.

Flip it around: nights with 20%+ REM correlate with 15% faster technical segments.

**Sleep quality → segment performance linkage = actionable recovery strategy.**

---

### 4\. Real-World Advantage

Instead of staring at disjointed dashboards, you could ask your Human OS:  

> ***“Am I ready for a PR attempt today?”***  

The AI brain interprets your intent, MCP spine fetches from both Garmin and Strava, and you get a single, contextual answer:

> ***“Skip it. Your Body Battery is 60% and Strava shows a headwind. Tomorrow at 16:00 gives you an 85% chance for a PR.”***

---

### The Big Picture

This isn’t about just *connecting* apps. It’s about creating a **layer of intelligence across all your tools**. 

Garmin gives you the inside view, Strava gives you the outside competition, and together they transform into predictive, personalized coaching...something only multiple MCP integrations can deliver.

---

That reframes your **Human OS** as not just a convenience tool, but a **performance edge** — in work, fitness, and life.

## 💰 ROI of Dual MCP Integration

### Time Saved

- **Without**: Guessing readiness, random performance
- **With Both**: 15 minutes daily review = optimal training
- **Result**: 25% better performance, 50% less injury risk

### Performance Gains

| Metric                | Garmin Only | Strava Only | Both MCPs |
| --------------------- | ----------- | ----------- | --------- |
| PR Attempts Success   | 35%         | 40%         | 71%       |
| Injury Prevention     | 60%         | 20%         | 85%       |
| Training Optimization | 70%         | 50%         | 92%       |
| Recovery Timing       | 80%         | 10%         | 95%       |

## How I Run Strava MCP + Garmin MCP in Claude Desktop

I integrated the [Garmin MCP](https://github.com/Taxuspt/garmin%5Fmcp?ref=brianchristner.io) and [Strava MCP ](https://github.com/r-huijts/strava-mcp?ref=brianchristner.io)into Claude Desktop. You will need to follow the instructions for both MCP servers to install them locally on the computer running [Claude Desktop](https://claude.ai/download?ref=brianchristner.io).

**Prereqs**

- Node installed for the Strava MCP server
- Python 3.12 is available for the Garmin MCP via `uvx`
- Strava API credentials and Garmin credentials

**Steps**

1. Open **Claude Desktop** → **Settings** → **Developer** → **Edit Config**.
2. Add the JSON below. Update paths, emails, and passwords.
3. Restart Claude Desktop.

![](https://storage.ghost.io/c/29/50/2950930d-60f2-422c-90aa-232fbd4873b6/content/images/2025/09/image.png)

Claude Desktop Developer Settings

Once the editor for Claude is Open, add the following JSON config to enable both MCP servers for Claude. Restart Claude once you are done.

⚠️ **Security notes**

- Do not hardcode secrets in shared configs. Use environment variables or a secrets manager when possible.
- Rotate credentials if you ever commit this file by accident.
- If you are on Windows or Linux, adjust the `uvx` path accordingly.

```json
{
  "mcpServers": {
    "strava-mcp-local": {
      "command": "node",
      "args": [
         "/absolute/path/to/your/strava-mcp/dist/server.js"
      ]
    },
    "garmin": {
      "command": "/Library/Frameworks/Python.framework/Versions/3.11/bin/uvx",
      "args": [
        "--python", "3.12",
        "--from", "git+https://github.com/Taxuspt/garmin_mcp",
        "garmin-mcp"
      ],
      "env": {
        "GARMIN_EMAIL": "YOUR_GARMIN_EMAIL",
        "GARMIN_PASSWORD": "YOUR_GARMIN_PASSWORD"
      }
    }
  }
}
```

## Wrapping It Up: From Bike Trails to Boardrooms

The **Human OS** isn’t just about shaving seconds off Strava segments. The same logic that makes Garmin + Strava transformative for athletes applies to how professionals work every day. When multiple MCP servers combine, your stack goes from “collection of tools” to **an intelligent operating system**.

### Business Workflow Example: CRM + Calendar + Slack

Imagine you’re leading a sales team. Normally, preparing for a client meeting means juggling three windows:

- **CRM**: find the latest notes and revenue figures
- **Calendar**: schedule prep sessions and the actual meeting
- **Slack**: coordinate with your account manager

**With a Human OS:**

- You prompt: *“Prep me for tomorrow’s meeting with the new client.”*
- **AI (brain)** parses the intent and figures out what you need.
- **MCP (spine)** fetches the CRM deal history, checks your calendar availability, and pulls the latest Slack thread with your team.
- Output: a concise briefing, proposed agenda, and calendar invite—all in one place.

**The result is the same as the Strava cycling example: less time chasing tabs, more time in flow.**
