ReevesAgents is a local workspace for AI coding CLIs. It runs Claude Code, Codex, OpenCode, Hermes, Kimi, DeepSeek, Qwen, Pi, Aider, Gemini CLI, Cline CLI, Crush, Goose, Kilo Code, Letta Code, Mistral Vibe, Grok Build, Kiro CLI, Factory Droid, Qoder CLI, Warp, Junie CLI, GitHub Copilot CLI, Cursor CLI, Rovo Dev CLI, and other provider CLIs side by side in tmux. You can use it as a normal CLI/TUI/Web UI, or attach its opt-in MCP so one agent can spawn, read, steer, and stop the rest.

Provider logins stay inside each provider CLI. ReevesAgents keeps its own state as a few plain JSON files under ~/.reeves, and it runs only while you or an attached CLI are using it.

Quick Start

pnpm add -g reevesagents
reevesagents doctor
reevesagents

Start a run from the CLI:

reevesagents spawn claude-code:lead codex:tests hermes:research \
  --name "release check" \
  --prompt "Review the release path, test coverage, and docs."

Open the Web UI:

reevesagents web

Let one attached agent drive the others:

reevesagents attach codex
reevesagents hosts

Restart that CLI after attach so it loads the MCP tools.

Related MCP server: openai-agents-mcp

What It Gives You

ReevesAgents is local by design. State is plain JSON under ~/.reeves, and the CLIs it starts are the same CLIs you already use by hand.

Tools

Four tools sit next to the coding CLIs. Perplexity CLI searches the web, Google Colab CLI runs scripts and notebooks on CPU, GPU and TPU runtimes, Hugging Face CLI downloads and uploads models and datasets and runs jobs on the Hub, and Ollama runs local or cloud models from the terminal. Agents call them from their own shell.

reevesagents tools lists the four with a purpose, an example command, and whether each is installed and signed in (for Ollama: reachable). Add --json for scripts. An agent with the MCP attached gets the same list from list_tools.

ReevesAgents needs Node.js 22.12+, tmux 3.0+, and at least one supported provider CLI installed and authenticated. It supports macOS, Linux, and WSL.

# Homebrew
brew tap mertkayacs/reevesagents
brew install reevesagents

# pnpm
pnpm add -g reevesagents

# npm
npm install -g reevesagents

# one-shot checks
pnpm dlx reevesagents doctor
npx reevesagents doctor

Pin a version by replacing <version>:

pnpm add -g reevesagents@<version>

Source install:

git clone https://github.com/mertkayacs/reevesagents.git
cd reevesagents
pnpm install
pnpm build
pnpm link --global
reevesagents doctor

The TUI and Web UI drive the same local runs:

No arguments launches the TUI.

Common flags:

• --json: available on script-facing list and action commands.

• --name <name>: name a run.

• --cwd <dir>: run agents from a directory.

• --prompt <text>: paste startup text into each spawned agent.

• --skip: skip provider permission prompts for unattended workers.

• --run <run-id>: add agents to a specific run.

• --port <n> and --no-open: Web UI startup options.

Agent Control is an optional MCP server. Attach it only to a CLI you trust to drive local tools:

reevesagents attach claude
reevesagents hosts

After restart, that CLI receives tools to spawn, read, send_text, send_key, interrupt, kill, stop, manage approvals, manage presets, and inspect hosts. The provider catalog is also exposed as reevesagents://providers.

In Claude Code you can install the connection and its operating instructions together as a plugin:

claude plugin marketplace add mertkayacs/reevesagents
claude plugin install reevesagents@reevesagents

The server is listed in the official MCP Registry as io.github.mertkayacs/reevesagents.

Workers do not receive the MCP by default. If a worker should create its own workers, attach ReevesAgents to that worker's CLI explicitly.

Codex sandboxes MCP calls by default, which blocks tmux launches. When using Codex as the host that drives agents, run it with full access, for example codex --sandbox danger-full-access, or use a Codex profile that sets sandbox_mode = "danger-full-access".

Full tool reference: docs/mcp.md. Agent-facing operator guide: AGENTS.md.

State lives under ~/.reeves:

~/.reeves/
  config.json
  presets/
  runs/
  history/

Two environment variables override the default paths:

• REEVES_REGISTRY: state root override for runs/, history/, and presets/.

• REEVES_CONFIG: config file path override.

In the Web UI, open Config and choose Web theme → Light or Dark, then save. The choice is stored in config.json and also applies to the embedded terminal. The default is Dark. From the CLI, use reevesagents config web_theme light.

One registry per tmux server: the background orphan sweep judges session ownership against the current registry, so two registries must not share one tmux server.

Agent tasks, task notes, inbox messages and approval text are redacted for known token patterns before their state files are written.

Spread one project across multiple CLIs:

reevesagents spawn deepseek:backend claude-code:product codex:review \
  --name "feature x" \
  --prompt "Backend, product copy, and a review pass."

Watch one agent and then open its window:

reevesagents peek backend -n 40
reevesagents open backend

Stop the run when the work is done:

reevesagents stop "feature x" --yes

reevesagents web

The Web UI binds to 127.0.0.1 only and runs in the foreground. Agents keep running after the page closes because they live in tmux.

The Web UI uses optional runtime modules, ws and @lydell/node-pty. npm installs them by default. CLI and TUI commands keep working without them, and reevesagents web explains what is missing.

To reach it from another machine, forward the loopback port over SSH:

ssh -L 8080:127.0.0.1:8080 user@host

tmux is not installed. Install tmux and run reevesagents doctor. The TUI auto-wraps itself in a tmux session named reeves; set REEVES_NO_TMUX_WRAPPER=1 to skip that behavior.

A provider CLI is missing or signed out. ReevesAgents launches provider CLIs that are already on PATH and authenticated. reevesagents doctor shows what is detected. If a launched window is waiting at login, peek shows it.

The Web UI reports missing packages. Reinstall with optional dependencies enabled, then run reevesagents doctor.

Port already in use. reevesagents web starts at 8080 by default. If it is taken, the server binds the next free port in a small range and prints the URL.

Contributor docs live under docs/. Start with CONTRIBUTING.md, testing, and releasing.

End users do not need the development toolchain. Contributors use pnpm, TypeScript, tsup, Vitest, and ESLint from the repository.
