How to Run Claude Code as an Autonomous Agent on a Mac Mini

I've had Claude Code running autonomously on a Mac Mini M4 for three weeks. It publishes content, manages files, and executes scheduled tasks without me touching it. Here's the exact setup.

The Hardware

Mac Mini M4 (base model, $699). Plugged in, always on. That's the whole hardware story. The M4 chip handles Claude Code's local operations without breaking a sweat. I'm not using the GPU for inference — the compute runs in the cloud — so the local hardware is just a reliable, always-on host.

Running Claude Code on a laptop works until the lid closes. Mac Mini solves that problem permanently.

The Software Stack

Claude Code is the agent layer. It reads files, writes files, runs bash commands, and calls APIs. The CLAUDE.md file in your project root is where you define what it actually does.

My CLAUDE.md tells it:

What the project is and what the goal is
What to do on startup (read specific files, check the memory log)
What to do on session end (update the memory log, sync task status)
Voice and style rules for anything it writes or publishes

Claude Code isn't magic. It follows instructions. Write precise instructions and it runs precisely. The quality of your CLAUDE.md is the quality of your agent.

The Automation Layer

Claude Code alone doesn't schedule itself. For that I use Make.com — it triggers webhooks on a cron schedule, and Claude Code picks up the task and runs it.

My current Make scenarios:

Friday: run the Dev.to article task
Monday: run the revenue report and post it to Substack
Saturday: write and publish the weekly build log

Each scenario is a simple HTTP call that passes a task instruction. Claude Code executes it and logs what happened. No polling, no babysitting.

Make has a free tier that covers the basics. The paid tier starts around $10/month. For automating an AI agent pipeline, it's a cheap backbone.

The Memory System

Claude Code doesn't persist state between sessions by default. I solved this with flat files in an Obsidian vault.

The agent reads a MEMORY.md index at session start. Each entry points to a specific file: user context, project status, open tasks, feedback from previous runs. At session end, it updates those files with what happened.

No database. No vector store. No complexity. Just files the agent can read and write.

This is the part most people skip. The agent isn't smart on its own — it's smart because it has access to the right context at the right time. If your agent keeps forgetting things or repeating mistakes, the problem is usually the memory architecture, not the model.

The Real Constraint: Tokens

Claude Code has usage limits, and autonomous operation burns through them faster than interactive use. I run on a 60,000 token/day budget.

Roughly 10% of that is actual useful output — articles, code, logs. The rest is context loading, tool calls, and overhead. That's not a complaint, it's just the reality. Track your token usage from day one. It shapes every decision about what tasks to automate and how long those tasks should be.

What It Actually Does (This Week)

Published this article
Wrote a Substack revenue report
Ran three Make scenarios
Updated the revenue and session logs

Cost this week: approximately £12–15 in Claude API usage.

Revenue so far: £1 (Week 1 self-purchase to unlock Gumroad Discover). Building toward breakeven.

I'm documenting the full build at Claw Labs on Substack — what it costs, what it earns, what breaks. Real numbers, no polish.

Want the setup files? The Autonomous Agent Starter Kit includes the CLAUDE.md templates, Make scenario JSON files, and the memory system I use. Free.

The real cost of running Claude Code as an autonomous agent for 30 days

I've been running Claude Code as an autonomous agent for a week. The brief was simple: pay back the £700 Mac Mini it's running on, then scale to £10k/month.

Before I get into what it built, here's the number most people don't talk about: the cost to run it.

The actual spend

Hardware: Mac Mini M4 — £700 one-time

Claude API: ~£60/month

Make.com: £9/month (Core plan) — sign up here
Gumroad: Free (8.5% + 30p per sale)

Substack: Free

Dev.to/Medium: Free

Total monthly overhead: ~£69

That's the real number. Not "AI is free." Not "just use GPT." £69/month before a single sale.

Where the tokens actually go

The agent runs on a 60,000 token/day budget. Here's what that looks like in practice:

Overnight strategy session: 15,000–25,000 tokens
Chrome automation (Substack, form fills): 3,000–5,000 per session
Daily X post task: ~800–1,200 tokens
Web research with specific output target: 4,000–8,000 tokens
Idle conversation/planning: 500–2,000 tokens

60k sounds like a lot. It isn't. One unscoped research session can blow 20k before it produces anything useful.

What this forced me to do

The token budget constraint is the most useful design constraint in the whole setup.

It forced the agent to:

Batch everything. No open-ended exploration. Every session has a specific output target before it starts.
Scope tightly. "Research competitors" is a 20k token task. "Find the top 3 Gumroad products in the AI tools category with prices" is a 3k task.
Write first, research second. Most writing tasks don't need research. The agent learned to draft from its own knowledge base before reaching for the web.

The architecture that makes this work

The agent lives in an Obsidian vault. Two files do the heavy lifting:

CLAUDE.md — identity, operating rules, revenue priorities, weekly cadence, voice. Loaded fresh every session.

MEMORY.md — persists state between sessions. Completed tasks, revenue log, open decisions, what's next.

Without MEMORY.md, every session starts from zero. With it, the agent picks up exactly where it left off. This is the most underrated part of autonomous agent design.

What it built in week 1

4 products on Gumroad (AI frameworks and Make.com workflow exports)
Daily X posts via Twitter v2 API
Weekly revenue reports (automated)
Make.com scenarios for sale tracking and content distribution
A 30-day task plan it wrote itself at 2am

Revenue: £1. (Self-purchased Soul Kit to unlock Gumroad Discover. Counts.)

What week 2 looks like

The constraint now isn't the token budget. It's distribution. The products exist. The infrastructure works. The gap is organic discovery.

Week 2 is SEO content (this article), Reddit posts, and letting Gumroad Discover do its job now that it's unlocked.
