gpt2099 

A Nushell scriptable

MCP client

with editable context threads

stored in cross.stream

Features

• Consistent API Across Models: Connect to Anthropic, Cerebras, Cohere, Gemini, and OpenAI

through a single, simple interface. (Add providers easily.)

• Persistent, Editable Conversations:

Conversation threads are

saved across sessions. Review, edit, and control your own context window — no black-box history.

• Flexible Tool Integration: Connect to MCP servers to extend functionality. `gpt2099` already

rivals Claude Code for local file

editing, but with full provider independence and deeper flexibility.

• Document Support: Upload and reference documents (PDFs, images, text files) directly in

conversations with automatic content-type detection and optional caching.

Built on cross.stream for event-driven processing, `gpt2099`

brings modern AI directly into your Nushell workflow — fully scriptable, fully inspectable, all in

the terminal.

Getting started

Step 1.

First, install and configure `cross.stream`. Once set up, you'll

have the full `cross.stream` ecosystem of tools for editing and

working with your context windows.

• https://cablehead.github.io/xs/getting-started/installation/

After this step you should be able to run:

"as easy as" | .append abc123
.last abc123 | .cas

Step 2.

It really is easy from here.

overlay use -pr ./gpt

Step 3.

Initialize the cross.stream command that performs the actual LLM call. This appends the command to

your event stream so later `gpt` invocations can use it:

gpt init

Step 4.

Enable your preferred provider. This stores the API key for later use:

gpt provider enable

Step 5.

Set up a `milli` alias for a lightweight model (try OpenAI's `gpt-4.1-mini` or Anthropic's

`claude-3-5-haiku-20241022`):

gpt provider ptr milli --set

Step 6.

Give it a spin:

"hola" | gpt -p milli
