## Description
Your own WhatsApp as an MCP server: read, search and send from any MCP client.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "whatsapp": {
    "command": "npx",
    "args": ["-y","whatsapp-5"]
  }
}
```

## Documentation & README

# wacli.me

Hosted MCP gateway in front of the [wacli](https://wacli.sh) WhatsApp CLI.

The idea: someone links their WhatsApp account once (QR, like WhatsApp Web) and gets a URL plus a
bearer token. Any MCP client can then read, search — and optionally send — without running anything
locally.

Status: **public alpha**. Single host, single process. Live at <https://wacli.me>.

MIT licensed. Self-hosting is a first-class path — see "Running" below.

## Layout

```
server/      Node MCP server (Streamable HTTP) + static file serving
site/        website sources (pages + layout + assets)
web/         generated site, built from site/ by scripts/build.mjs — never edit
config/      tenants.json (gitignored) — token -> store mapping
bin/wacli    pinned wacli binary, isolated from any system install
stores/      one wacli store directory per tenant (gitignored)
scripts/     start/stop/tunnel helpers
```

## Endpoints

| Path       | Purpose                                             |
|------------|-----------------------------------------------------|
| `/`        | landing page                                        |
| `/mcp`     | MCP over Streamable HTTP, `Authorization: Bearer …`  |
| `/healthz` | liveness + tenant count                             |
| `/connect` | self-service linking: live QR, issues a token        |
| `/.well-known/oauth-*` | OAuth 2.1 discovery — clients fetch their own credentials |

## Tenants

`config/tenants.json`:

```json
{
  "tenants": [
    { "id": "demo", "token": "<32 random bytes, hex>", "store": "/Users/<user>/wacli-me/stores/demo", "allowSend": false }
  ]
}
```

The file is re-read every 5 seconds — adding a tenant needs no restart. A token maps to exactly one
store directory; tools are constructed per request against that store, so two tenants cannot see each
other's data. `allowSend` is what registers the `send_message` tool at all; leave it `false` unless
the account owner explicitly asked for write access.

Generate a token with `openssl rand -hex 32`.

## Running

```bash
npm install --prefix server
node scripts/build.mjs                        # site/ -> web/
PORT=8787 HOST=127.0.0.1 node server/server.mjs
```

Environment:

| Variable            | Default              | Meaning                      |
|---------------------|----------------------|------------------------------|
| `PORT`              | `8787`               | listen port                  |
| `HOST`              | `127.0.0.1`          | bind address — keep loopback, expose via tunnel |
| `WACLI_BIN`         | `./bin/wacli`        | wacli binary                 |
| `WACLI_ME_TENANTS`  | `./config/tenants.json` | tenant file               |

## Linking an account

```bash
bin/wacli --store stores/<tenant> auth        # prints a QR, scan it on the phone
bin/wacli --store stores/<tenant> sync        # backfill history (long-running; run as a daemon)
```

Without a sync daemon the store only holds what was fetched during the last run.

## Security notes

- Bind to loopback and publish through a tunnel; never expose the port directly.
- Every MCP request needs a valid bearer token; tokens are compared in constant time.
- Reads run wacli with `--read-only`, so a compromised tool call cannot mutate the store.
- The QR link is a *linked device*. Whoever holds the store can read that account's messages —
  treat store directories and tenant tokens as credentials.

Linking an account uses an unofficial WhatsApp client. That is against WhatsApp's terms of service,
and Meta may block a number for it. Run it on accounts you own, and tell your users the same.
