Build Your Own Jarvis with Claude Code: The Complete Stack

The complete list of tools and connectors to turn Claude Code into a personal assistant that tracks your revenue, answers your emails, posts your content, and runs before you wake up.

Everyone fantasizes about a Jarvis-style assistant: you talk to it, it runs your business, it works while you sleep. The good news is you can build it today, and it is not some magic product at 500 dollars a month. Your Jarvis is just Claude Code plugged into your apps, one connector at a time.

The word to remember is connector (or MCP, its technical name). A connector is a direct line between Claude and one of your apps: your email, your ads, your revenue tool. Plug in one, Claude knows how to use it. Plug in ten, it runs your business.

This guide gives you the complete stack, tool by tool. You do not need to build it all at once: you add one capability at a time, in whatever order works for you.

✅What you need before you start
1
A paid Claude plan and Claude Code. Claude Code is the version of Claude that acts instead of just answering. It is the brain of your Jarvis.
2
Your everyday apps. No new tool to learn. You plug in what you already use: email, content, ads, revenue.
3
The right mindset. You build your Jarvis brick by brick. One capability that works beats ten half-wired ones.
The thing to understand

Jarvis is not a product you buy. It is Claude Code, plus one connector per capability. You build your own, and you decide how far you go.

1

The brain of your Jarvis

🔗 claude.com/product/claude-code

Before you give it hands, you give it an interface and a voice.

🖥️
The dashboard, with Claude Code
Want a Jarvis-style interface? Drop a simple screenshot of the dashboard you have in mind into Claude Code, and it codes it for you. No mockup to draw: you describe, it builds.
🎙️
The voice, with /voice and ElevenLabs
The /voice command lets you talk to it out loud. ElevenLabs gives it a real voice to answer you, Jarvis-style with a British accent if you want.
Where to start

Build the dashboard and the voice first. That is what makes it feel real and makes you want to wire up the rest.

Let it act on its own

📍 anthropic.com → Claude for Chrome

An assistant that answers is nice. An assistant that acts for you is a Jarvis.

🌐
Your browser, with Claude for Chrome
Claude takes over your browser: it clicks, it fills, it navigates. For the more advanced, Playwright MCP does the same with more control.
🤖
A team of agents, with Subagents
Instead of a single assistant, you create specialized subagents: one for research, one for support, one for reporting. Each has a precise job.
⏰
Before you wake up, with Routines
With /schedule, you schedule your Jarvis: it runs on its own at the time you choose, your computer off, in the cloud.
Good to know

When your Jarvis acts (browser, email, posting), it acts under your identity. Only wire up the access it needs for the task at hand.

Your business on autopilot

📍 claude.ai/customize/connectors

This is the heart of it: you plug in your business, capability by capability.

💰
Track your revenue, with RevenueCat
The RevenueCat connector gives Claude your subscription numbers live. You ask "where am I this month", it answers.
📲
Auto-post, with Buffer
The Buffer connector lets Claude schedule and post your content. Postiz does the same if you prefer open source.
📊
Your Instagram analytics, with Meta
A Meta developer app plus a token, handed to Claude, and it reads your Instagram stats for you.
🎯
Read and run your ads, with Meta Ads
The Meta Ads connector lets Claude read your campaigns and launch new ones. Your ads driven by prompt.
📩
Read your inbox, with Gmail
The Gmail connector lets Claude read and sort your inbox. The Google Workspace CLI does the same, more thoroughly.
🗣️
Answer in your voice, with a markdown base
Give Claude your knowledge base as markdown files (your stock answers, your tone), and it answers your customers like you.
The recommended order

Start with the capability that saves you the most time today: often email or content. Once it runs, you add the next one.

How to start without drowning

The worst mistake is trying to wire up everything on night one. Pick a single capability from the list, the one that removes your heaviest chore this week. Plug in the connector, check that Claude actually uses it, and use it for real for a few days.

Once it is part of your routine, you add the next brick. That is how you go from a chatbot to a real assistant that runs your business: not in a weekend, but in a few connectors added at the right pace.

The takeaway

Your Jarvis is worth exactly what the connectors you wire into it are worth. One, used well, already changes your week. The complete stack changes your business.
