Description: A tmux-backed agent pool with MCP server for orchestrating interactive CLI agents
Latest version: 0.1.0

**I have a new version which name is Hydra,more powerful,see detail in [https://github.com/JinchengGao-Infty/Hydra?tab=readme-ov-file](https://github.com/JinchengGao-Infty/Hydra?tab=readme-ov-file)**


# Agent Mux

Agent Mux is a **tmux-backed agent pool** plus a small **MCP (Model Context Protocol) server**.
It manages “projects” as tmux sessions, and spawns each interactive agent as a tmux window so you can:

- Create/list/switch/close projects (tmux sessions)
- Spawn/list/attach/interrupt/kill agents (tmux windows)
- Send text to an agent (type + Enter)
- Read output from an agent (via `tmux capture-pane`)

This repo keeps the agent-mux implementation under `lib/agent-mux/`, and exposes it as MCP tools via
`servers/agent-mux-server.mjs`.

## Why tmux?

tmux provides durable sessions you can inspect manually, and a simple way to capture rendered terminal
output—making it a practical substrate for orchestrating interactive CLI agents.

## Features

- **Dedicated tmux socket**: uses `tmux -L ccx ...` so it won’t interfere with your default tmux
- **One project = one session**, **one agent = one window** (single pane)
- **Persistent registry** under `.ccx/projects/<project>/agents.json`
- **Per-agent log file** via `pipe-pane` to `.ccx/projects/<project>/logs/<agent>.log`
- **Conservative name validation** for projects and agents

## Requirements

- Node.js 18+ (ESM)
- `tmux` in `PATH`
- Optional agent CLIs (only needed if you use default commands):
  - `claude` (default args: `--dangerously-skip-permissions`)
  - `codex` (default args: `--yolo`)
  - `gemini` (default args: `--yolo`)

## Installation

From the repo root:

```bash
npm install
```

## Quick start (manual tmux)

After you create a project and spawn agents, you can inspect the tmux session:

```bash
tmux -L ccx attach -t <project>
# Detach without closing: Ctrl-b d
# Switch windows: Ctrl-b 0/1/2/...
```

## Quick start (MCP server)

Run the MCP server (stdio):

```bash
node servers/agent-mux-server.mjs
```

Then register it in your MCP client as a stdio server. Example (client formats vary):

```json
{
  "mcpServers": {
    "agent-mux": {
      "command": "node",
      "args": ["servers/agent-mux-server.mjs"]
    }
  }
}
```

## Usage examples

### Via MCP tools

Typical flow:

1) Create/select a project

- `create_project({ "name": "my-project", "cwd": "/path/to/workdir" })`
- `switch_project({ "name": "my-project" })`

2) Spawn an agent

- `spawn_agent({ "type": "codex", "name": "codex-1" })`

3) Talk to it

- `send_to_agent({ "name": "codex-1", "text": "hello" })`

4) Read output

- `read_agent_output({ "name": "codex-1", "lines": 50 })`

### As a library (Node.js)

```js
import { AgentMux } from "./lib/agent-mux/index.mjs";

const mux = new AgentMux({ projectRoot: process.cwd(), tmuxSocketName: "ccx" });

mux.create_project("my-project", process.cwd());
mux.spawn_agent("codex", "codex-1");
mux.send_to_agent("codex-1", "hello");

const { output } = mux.read_agent_output("codex-1", 50);
console.log(output);
```

## MCP tools

The MCP server exposes these tools (names match the `AgentMux` methods):

### Project management

- `create_project({ name, cwd? })`
- `list_projects({})`
- `switch_project({ name })`
- `close_project({ name })`

### Agent management

- `spawn_agent({ type, name, options? })`
- `list_agents({ project? })`
- `attach_agent({ name })`
- `interrupt_agent({ name })`
- `kill_agent({ name })`

### Agent I/O

- `send_to_agent({ name, text })`
- `read_agent_output({ name, lines? })`
- `send_to_window({ window, text })`

## API (library)

### Naming rules

Project names and agent names must match:

- `^[a-zA-Z0-9][a-zA-Z0-9._-]{0,127}$`

### `new AgentMux(options?)`

- `options.projectRoot` (string): base dir used for registry/log storage; default `process.cwd()`
- `options.tmuxSocketName` (string): tmux socket name for `tmux -L`; default `ccx`
- `options.tmuxBinary` (string): tmux binary; default `tmux`

### Project management

- `create_project(name, cwd?)` → `{ project, cwd, created, storageDir }`
- `list_projects()` → `Array<{ project, cwd, sessionExists, hasRegistry, current }>`
- `switch_project(name)` → `{ project, switched, clients }`
- `close_project(name)` → `{ project, killed, clearedCurrent }`

### Agent management

- `spawn_agent(type, name, options?)` → agent entry (tmux window + registry + log path)
  - `type`: one of `claude` / `codex` / `gemini`
  - `options.cwd` (string): agent working dir (defaults to project cwd)
  - `options.command` / `options.cmd` (string): override executed command
  - `options.args` (string[]): extra args appended to defaults (or used with custom command)
- `list_agents(project?)` → `{ project, agents: [...entries with alive:boolean] }`
- `attach_agent(name)` → `{ project, agent, attached, clients }`
- `interrupt_agent(name)` → `{ project, agent, interrupted }` (sends `Ctrl+C`)
- `kill_agent(name)` → `{ project, agent, killed }`

### Agent I/O

- `send_to_agent(name, text)` → `{ project, agent, sent, bytes }`
- `send_to_window(window, text)` → `{ project, window, sent, bytes }`
- `read_agent_output(name, lines=200)` → `{ project, agent, lines, output }`

## Storage layout

By default, Agent Mux stores state under `projectRoot/.ccx/projects/`:

```text
.ccx/projects/<project>/
  project.json
  agents.json
  logs/<agent>.log
.ccx/projects/current.json
```

If `.ccx/` is not writable, it falls back to `${os.tmpdir()}/ccx-agent-mux/projects/`.
