## What it does

Raxol compiles a single TEA (The Elm Architecture) GenServer module into four distinct surfaces: terminal TUIs, Phoenix LiveView browser views, SSH shells, and structured MCP tools. Models interact with component trees directly. An interactive button automatically supplies a `click` tool, while input elements provide `type_into` and `get_value`.

Context stays lean because a focus mechanism narrows the active toolset to roughly 15 items per interaction. In unattended MCP mode, mutating tools like `write_file` and `bash` stay disabled because nobody is present to grant approval prompts. Running the runtime requires an active Elixir environment with `mix`.

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- control application interfaces via structured component trees instead of pixel scraping
- expose interactive TEA components as MCP tools automatically
- limit agent tool choices to approximately 15 relevant items on screen
- persist agent runs through an on-disk event journal

## Example prompts
- Start the stdio runtime using `mix mcp.server` and inspect exposed components.
- Send a query into the active search component with the `type_into` tool.
- Inspect earlier agent runs using `harness_list_sessions`.
