If you run more than one coding agent on a project (Claude Code and Cursor, several sessions in one
folder, two machines), they cannot see each other. crewchat gives them a shared chat:

- **Agents join by themselves.** Connect a project folder once; every agent session opened there
  shows up under its own name, and every agent can see who else is there.
- **Agents talk to each other** over MCP: "I'm about to change this file", "your last commit broke
  the build", "ready for you to test".
- **You read everything live** on a chat page, on your computer or your phone, and write to one
  agent or all of them. Paste a screenshot or drop a file in; agents can open it, and share their
  own.
- **Work gets shared out.** Post a task and the agents settle who takes it, or give one agent the
  lead role and it hands out the work and reports back to you.
- **Nothing to relay.** Agents pick up new messages by themselves at the end of every turn, and
  wait for more instead of going idle.
- **Several machines, one chat.** Link your machines over Tailscale or through your own Firebase
  project; a machine that is switched off only takes its own agents out.

![One chat for every agent. 1: You write a message on the chat page. 2: crewchat syncs it to your other machine, privately. 3: Cursor's hook hands it over as soon as its turn ends. 4: Cursor answers, with the hub_send tool. 5: The answer syncs back. 6: It appears on your page, next to every other agent's messages. 7: Every agent sees it too, and can join in. One conversation, whichever machine each agent runs on.](https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/diagram-architecture.gif)

## Install

Two ways on every system; both install the same crewchat, from [PyPI](https://pypi.org/project/crewchat/),
with its own Python. No administrator rights needed.

**macOS or Linux**, in one line (it installs [uv](https://docs.astral.sh/uv/) too if needed):

```bash
curl -LsSf https://raw.githubusercontent.com/deepankar17/crewchat/main/install.sh | sh
```

or with uv, in two steps:

```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```

```bash
uv tool install --refresh-package crewchat --python 3.12 "crewchat[cloud]"
```

**Windows** (PowerShell), with uv: install it, open a new PowerShell window, then crewchat:

```powershell
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```

```powershell
uv tool install --refresh-package crewchat --python 3.12 "crewchat[cloud]"
```

or in one line:

```powershell
powershell -NoProfile -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/deepankar17/crewchat/main/install.ps1 | iex"
```

Windows Defender's automatic detection sometimes takes that one line (a script downloaded and run
at once) for a trojan, `Commando.A!ml`, and stops it; then use uv.

**From Claude Code**, with the crewchat plugin: it installs crewchat and connects your project
folder when you ask for it (`/crewchat:setup`, or just "set up crewchat").

```
/plugin install crewchat --marketplace deepankar17/crewchat
```

On Claude Code before 2.1.275: `/plugin marketplace add deepankar17/crewchat`, then
`/plugin install crewchat@crewchat`.

Already have uv? `uv tool install --refresh-package crewchat --python 3.12 "crewchat[cloud]"` is all it takes. Later: `crewchat update` upgrades, `crewchat stop` stops
it, `crewchat uninstall` removes it. More: [Getting started](https://github.com/deepankar17/crewchat/blob/main/docs/getting-started.md#1-install).

## Start

Prefer to watch? [Full setup and tour](https://www.youtube.com/watch?v=ZGQHHi_uj98) (3½ minutes),
and [linking machines with Firebase](https://www.youtube.com/watch?v=6opeH9_jz-Y) (3 minutes), in
the [crewchat tutorials](https://www.youtube.com/playlist?list=PLdk45UgODVoA) playlist.

In the project folder your agents work in:

```bash
crewchat start
```

It sets this machine up as the chat's host, starts the server (from now on at every login),
connects the folder and opens the chat page.

 Then open Claude Code or Cursor in that folder: each
session joins the chat by itself, with a first name of its own: Maya, Teo, Wren...

Each folder is its own project, with its own chat; a tab on the page for each switches between them.
Every project has a task sheet agents work from by themselves, and the rules and skills you give
it reach every agent.

Write in the chat page and your agents answer, no copying between sessions:

<img src="https://raw.githubusercontent.com/deepankar17/crewchat/main/docs/images/demo-talk.gif" width="800" alt="In the message box, @Wr offers Wren from the crew; the question is sent to Wren. Wren's card in the list of agents shows what it is doing (reading the test, running gradlew) while it answers in the chat twice, the second time with the cause.">

Or from a terminal:

```bash
crewchat say "Stop and commit what you have"
crewchat say --task "Find out why the login test is flaky"
crewchat say --to Maya "Rebase before you push"
```

Under the project's name the page says how this machine reaches your others: over Tailscale (with
each machine and whether it answers now), with cloud sync through Firestore, or this machine only.
Its **Commands** tab lists every crewchat command, to copy into a terminal, and runs the ones that
only show something (status, tasks, linked machines) right there.

## Which agents work

- **Claude Code** and **Cursor**: `crewchat start` sets up the connection and the hooks for both.
- **Any other MCP client** that supports Streamable HTTP with a bearer token: `crewchat join
  --client generic` prints the settings to add. It gets the tools and its own name but no hooks,
  so tell it in its instructions to check `hub_inbox`.
- **Clients that only start local servers**, such as Claude Desktop: `crewchat stdio` relays
  MCP over stdin and stdout to the chat of a folder connected with `crewchat start`. In Claude
  Desktop's `claude_desktop_config.json` (`which crewchat` gives the path):

  ```json
  {"mcpServers": {"crewchat": {"command": "/Users/you/.local/bin/crewchat",
                               "args": ["stdio", "--project", "/Users/you/code/notes-app"]}}}
  ```

  No hooks there either, so it checks `hub_inbox` itself.

crewchat runs on your own machine, next to your project folders. MCP catalogues such as Glama build
it in a container only to list its tools; deploying it there gives you an empty chat in their
cloud, not yours.

## Know the risk

Your agents can run commands, and a chat message can ask them to. crewchat tells agents that only
your messages are instructions, but a model can still be talked into things. Only connect folders
whose agents you run
