What is MahanAI?

MahanAI is a terminal AI agent you install with pip. It gives you a powerful chat interface, agentic tool use (run commands, read/write files, search the web), and a local gateway server that makes all your configured AI providers available as a single unified API endpoint — so any tool that speaks OpenAI or Anthropic format can point at it.

On top of that: a plugin system (.mmd files) with a GitHub-backed store, custom themes (.mai files), conversation branching, effort levels, plan mode, and 60+ slash commands.

New in Max 3.0

• Modern terminal composer — a three-line input bar, cyan prompt marker, and a clean model/effort/workspace status line
• Clipboard image input — paste multiple images directly into the prompt; image tokens can be removed with one Backspace
• Compact GitHub repository tokens — pasted repository references render as ◉ owner/repo, remain atomic while editing, and send the original URL to the model
• Persistent default model — /set-def-model opens the model selector and saves the choice for future sessions
• Expanded OpenAI models — GPT-5.5 plus GPT-5.6 Sol, Terra, and Luna in Direct and Indirect modes
• Improved Codex login — successful browser authentication opens the bundled MahanAI confirmation page

Install

pip install mahanai
mahanai

That's it. An onboarding wizard runs on first launch to help you pick a model, set up API keys, and connect GitHub for the plugin marketplace.

If you want a guided bootstrap that installs uv, installs Python through uv, installs mahanai, and launches it, use one of the included get-started scripts:

./scripts/get-started.sh

powershell -ExecutionPolicy Bypass -File .\scripts\get-started.ps1

If you use PowerShell Core, swap powershell for pwsh.

On macOS, you can also double-click scripts/get-started.command from Finder.

Highlights

• Gateway server — expose all your providers behind one OpenAI/Anthropic-compatible endpoint; works with Cursor, Continue, LM Studio, Claude Code, and more
• Plugin store — install community .mmd plugins with /store install, publish your own with /store upload
• Custom themes — write .mai theme files with gradients, color aliases, and display name overrides
• Multi-model — Claude (via Claude Code), NVIDIA NIM, OpenAI Codex, Ollama, and any OpenAI-compatible endpoint
• Multimodal prompts — paste multiple clipboard images alongside text in the terminal composer
• Repository-aware input — GitHub links collapse into editable ◉ owner/repo tokens without changing what the model receives
• Agentic tools — shell commands, file read/write/edit, web search, Python REPL, URL fetch — all with approval prompts and inline diffs
• Interact mode — enable once with /interact to let MahanAI control your computer with screenshots, mouse, and keyboard; Wayland helpers are used first, with X11 as a fallback; remove it later with /interact remove
• Plan mode & effort levels — /plan on to outline before acting; /effort high for deeper reasoning
• Conversation branching — save and restore conversation states to explore multiple paths
• Searchable chat history — search saved chats by keyword with /history search <query>
• Shell history awareness — inject your recent bash/zsh history into context with /shell-history inject
• Cost tracking — /cost shows session token usage and estimated spend
• Desktop notifications — get pinged when a long generation finishes

Gateway Server

Start a local HTTP server that routes requests to the right backend automatically:

mahanai --server                          # OpenAI-compatible on port 8080
mahanai --server --type anthropic         # Anthropic-compatible
mahanai --server --port 9000 --api-key sk-gaming

Point any OpenAI-compatible client at http://localhost:8080 and use model IDs like claude-sonnet-4-6, meta/llama-3.3-70b-instruct, gpt-5.6-sol-indirect, gpt-5.6-terra-indirect, gpt-5.6-luna-indirect, or your Ollama model name — MahanAI routes and converts formats automatically, including SSE streaming end-to-end.

A browser-based chat UI is also available at http://localhost:8080 when the server is running.

Models

Switch models interactively with /models or quick-switch with /mode claude / /mode default.

Provider	How to connect
Claude (Opus, Sonnet, Haiku)	Install Claude Code and sign in
NVIDIA NIM (Llama 3.3 70B)	/api-key-nvidia your-key
OpenAI Codex (GPT-5.5; GPT-5.6 Sol, Terra, Luna; earlier GPT-5 models)	/codex-login (browser OAuth, no API key needed)
GitHub plugin store	/store login (OAuth when configured, PAT fallback otherwise)
Ollama	/add-ollama name localhost 11434
Any OpenAI-compatible API	/custom http://your-server/v1 model-name

Default model on first launch: Claude Haiku 4.5

Plugins

Plugins are .mmd files that register new slash commands. They can delegate to Claude Code, MahanAI itself, or the shell, and they can now also embed default .mai themes or launch Tk windows from a trigger.

# Install from the store
/store install mahancreate/maifoundation.example.mahmod

# Load a local plugin
/plugin-load path/to/my-plugin.mmd

# Browse the store
/store browse
/store search compact

Publishing your own plugin is one command:

/store upload path/to/my-plugin.mmd

This creates a public GitHub repo, pushes the .mmd file, and tags it so it shows up in /store browse.

GitHub auth for the store works in two modes:

• Set MAHANAI_GITHUB_CLIENT_ID and run /store login for browser/device-flow OAuth
• Leave it unset and /store login falls back to a GitHub personal access token prompt

Plugin Extras

You can embed a default theme directly inside a plugin with newdeftheme(...):

newdeftheme(
theme.name = example-neon
theme.pretty.name = Example Neon

sky = #5B8DEF
mint = #34D399

ascii-art.default.color = gradient("sky -> mint")
message.ai.color        = color("sky")
message.user.color      = color("mint")
)

When the plugin is loaded, that theme is registered into /themes like any other .mai theme.

You can also open a Tk window from a plugin command with pytknwd(...):

add command("/example-window"){
    pytknwd(
root = tk.Tk()
root.title("Hello")
tk.Label(root, text="Window from MMD").pack()
root.mainloop()
    )
}

See example-mahanai-mahmod.mmd for a full example that includes both features.

Themes

Four built-in themes (midnight, light, midnight-cb, light-cb) plus full custom theme support via .mai files:

/themes midnight          # switch theme
/theme-load mytheme.mai   # load a custom theme

A .mai theme file looks like this:

theme.name        = my-theme
theme.pretty.name = My Custom Theme

blue = #5B8DEF
gold = #F5C842

ascii-art.default.color = gradient("blue -> gold")
message.ai.color        = color("blue")
message.user.color      = color("gold")
message.ai.name         = text("assistant")

---

Project Config (.mahanairc)

Place a .mahanairc in any project directory and MahanAI loads it automatically — pre-loading context files, auto-installing plugins, and activating dev kit extras scoped to that workspace.

load(location="context.md" type=context)
load(location="plugins/my-plugin.mmd" type=mmd)
load(python-dev-kit)
