Eai

Extreme minimal AI assistant — a pragmatic engineer's companion with a real Linux terminal, recursive sub‑agents, and a graph‑based memory engine. MCP servers and browsers are integrated via recommended CLI tools (mcporter, agent-browser) — no framework bloat.

Quick Start

# Install deps
mix deps.get && mix compile
pip3 install -r priv/scripts/requirements.txt

# Recommended external CLI tools
npm install -g mcporter agent-browser && agent-browser install

# Set API key
export OPENAI_API_KEY=sk-...
# (also ANTHROPIC_API_KEY if using Claude)

# Launch
iex -S mix

Basic Usage

# Interactive multi‑line chat (send with /s, cancel with /c)
Eai.Chat.talk()

# One‑shot question
Eai.Chat.talk(content: "List files", mod: :f)

# Switch model or persona
Eai.Chat.talk(model: :claude_sonnet, prompt: :coder, content: "Refactor this")
Eai.Chat.talk(chat_session: "work", content: "Setup CI")   # isolated session

Models & Prompts

Defined in config/models/*.exs and config/prompts/*.exs. List what's available:

Eai.Models.names()   # => [:deepseek, :gpt4o, :claude_sonnet, ...]
Eai.Prompts.list()   # => :momoka, :coder, :analyst

Tools

All tools live in config/tools/ and are called autonomously by the agent.

Tool	Purpose
execute_script	Run bash asynchronously → returns task_id
get_task_result	Poll async output
call_subagent	Dispatch a sub‑task to an independent agent
write_to_session	Send raw input to a PTY (e.g. Ctrl‑C)
read_media_file	Extract images/frames; optional vision analysis
export_context / replace_context	Save/load conversation history (gzip)

External CLI Tools (Recommended)

Eai does NOT bake MCP or browser support into the framework. Instead, the model uses ordinary CLI programs via execute_script — pure Unix philosophy. No tool schemas in the system prompt, no context overhead, no prefix-cache breakage.

McPorter — MCP client

McPorter (⭐4,652) is the de-facto CLI for Model Context Protocol servers.

npm install -g mcporter

# List configured servers (auto-discovers Cursor/Claude/Codex/VS Code configs)
mcporter list

# List tools on a server (TypeScript-style signatures)
mcporter list filesystem

# Call a tool
mcporter call filesystem.read_file path:/tmp/hello.txt

# Ad-hoc: connect to any MCP endpoint without config
mcporter call --stdio "npx -y @modelcontextprotocol/server-filesystem /tmp" --name fs

# Bridge: expose daemon-managed servers as one MCP endpoint
mcporter serve --stdio

Supports stdio, HTTP, SSE transports. Built-in OAuth, daemon keep-alive, record/replay.

Agent Browser — headless browser

Agent Browser provides compact accessibility-tree snapshots with @eN refs — ~200-400 tokens instead of raw HTML.

npm install -g agent-browser && agent-browser install

agent-browser open https://example.com
agent-browser snapshot -i          # interactive elements only

# Interact via @refs
agent-browser click @e1
agent-browser fill @e2 "text"

# Extract data
agent-browser get text @e1

Graph‑based Memory

Agents write RDF‑style triples <<{subject, predicate, object}. into files (e.g. TRANSITION.md). Query them with:

python priv/scripts/tools/dispatch.py <file_or_dir> path A B
python priv/scripts/tools/dispatch.py <file_or_dir> query A B 5

Discover all auxiliary tools:

bash priv/scripts/tools/bin/scan_tools.sh

Configuration

Key settings in config/config.exs:

config :eai, :sandbox, work_dir_root: "/home/eai_agents"
config :eai, :poll_cooldown_ms, 5_000   # min polling interval

Set EAI_DEBUG_PTY=1 to see raw PTY output.

Adding a Custom Model

Edit config/models.exs:

[
  name: :my_llama,
  model: "llama3",
  url: "http://localhost:11434/v1/chat/completions",
  provider: :openai_compat,
  api_key_env: nil    # no key needed
]

Architecture

Eai.Chat → Eai.LLM.Direct (adapter → API) → tool loop → Eai.Sandbox.PTYPool + Eai.Task
                                                                  │
                                          ┌───────────────────────┘
                                          ▼
                                     bash PTY
                                          │
                              ┌───────────┼───────────┐
                              ▼           ▼           ▼
                          mcporter   agent-browser   git, curl, ...
                          (MCP)      (browser)       (anything)

External tools are NOT framework code. They are ordinary CLI programs the model invokes naturally through its terminal. Zero coupling, maximum flexibility.
