Why? Multi-tenant environments. First, we need to understand a few differences between environments:

End-user UI
Agent Runtime Environment
LLM Server

When you run Claude Code on your local MacBook, the first two are always local. The third is usually the Claude.ai server.
When you ssh to a virtual private server (VPS) and install Claude Code there, the first two are your remote server. The third is still the Claude.ai server.
When you run Claude RC on your virtual private server and code from your iPad using the Claude app, the end-user UI is on your iPad, the agent runtime environment is on your VPS, and the server is still Claude.ai.

Most people physically separate their tenancy, such as Claude Code, from their personal vs. work laptops. So in most cases, it's not a big deal.

But when you need multi-tenancy, it becomes super stressful. For example, say you have two different toolkits:

personal toolkits (personal Notion, personal Sentry, personal Linear)
workplace toolkits (company Notion, company Sentry, company Linear)

Most MCP auth states or code harnesses don't support profiles, so you can only log in to one.

So therefore... a natural evolution was to have both:

a personal VPS with all personal toolkits set up
a workplace VPS with all workspace toolkits set up

to physically isolate tenancies.

Now we've solved the multiple-profile issue, but the client's problems persist. Now let's get back to the environments:

End-user UI
Agent Runtime Environment
LLM Server

All MCP auth or toolkit auth info should always be saved in the Agent Runtime Environment IMHO. However, a surprising number of harnesses tie them to the LLM server (such as Codex Apps or Claude.ai Plugins) or put them in the end-user UI (Claude Desktop or Codex Desktop).

Now the problem is:

If the auth data is put on the LLM server, you cannot reuse LLM accounts across tenants
If the auth data is put on the end-user UI, you cannot use the same app to access multi-tenants.

The only way to reliably isolate different auth information is thus:

You ssh to a virtual private server (VPS) and run Claude Code there. Never use LLM server plugins.

Then

End-user UI
Agent Runtime Environment

are both isolated VPS, and

LLM Server holds no information on the tenancy

This way, you can provide different toolkits, creating multiple dev environments.

Commonplace Book

A commonplace book is a type of personal journal that people use to document interesting quotes, thoughts, and information. This practice has been around since the Renaissance and helps individuals collect and reflect on knowledge over time. Commonplace books can serve many purposes such as collecting quotes, personal reflections, learning and memory, creative inspiration, categorization, and indexing. Even famous figures like Locke and Newton kept commonplace books to record their thoughts. Today, digital tools make it possible to continue this tradition by allowing individuals to collect personal knowledge and inspiration in a similar manner.

Why keep a diary...

One of my few prized possessions is this 70-page autobiographical book by my great-grandfather who was born in 1902 and was a farmer in France. Only a few copies were printed.

His chapter titles are truly amazing, each is about 1-2 pages:

I saw the beginning of electrification

I saw the first cars

I saw the first airplanes

I smoked my first cigarette at 7 years old

I saw a total solar eclipse

The telephone

1914: The war

I had the Spanish flu etc
