### Description (declared)

# codex-mcp-swarm

An MCP server that wraps OpenAI's Codex CLI with **true parallel execution** and **live task monitoring**. Zero dependencies -- single Python file, stdlib only.

## Why?

The official `codex mcp-server` processes requests sequentially. If your MCP client (Claude Code, etc.) needs to run 5 Codex tasks, they queue up one after another. This server spawns each task as an independent subprocess, so they run in parallel.

**Unique features no other Codex MCP wrapper has:**

- **Worktree isolation** -- `worktree: true` creates an isolated git worktree per task so parallel Codex instances never edit past each other
- **Batch wait** -- launch N tasks, call `codex_wait` once, get all results when they finish
- **Live status** -- see what each Codex task is doing right now (last tool call, current reasoning, progress)
- **Full flag parity** -- same parameters as the official Codex MCP tool (`sandbox`, `approval-policy`, `cwd`, `model`, `config`, etc.)
- **Drop-in config** -- accepts the same `-c key=value` server args as `codex mcp-server`

## Tools

| Tool | Description |
|------|-------------|
| `codex` | Synchronous execution (drop-in replacement for official); terminal failures include the model, structured cause, category, and retryability |
| `codex_async` | Launch a task, get a `task_id` immediately (fan-out). **Not** fire-and-forget: results come back only via `codex_wait`. Pass `threadId` to resume a session |
| `codex_reply` | Continue a previous session via `codex exec resume`; uses the same structured failure reporting as `codex` |
| `codex_status` | Live view: tools called, last command, current thinking, warnings, and terminal failure cause |
| `codex_wait` | Block until multiple tasks complete and return results or structured failure details |
| `codex_cancel` | Kill a running async task (preserves worktree for inspection); if it already failed, return the recorded cause |

## Installation

### Claude Code

```bash
claude mcp add codex-swarm…
