# sendpulse-whatsapp-mcp

[![ci](https://github.com/lieox/sendpulse-whatsapp-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/lieox/sendpulse-whatsapp-mcp/actions/workflows/ci.yml)

An MCP server that lets Claude (Claude Code, Claude Desktop, or any MCP client) work with a **SendPulse WhatsApp chatbot**: read bots, contacts and chat history, send messages and approved templates, tag contacts, run flows and send campaigns.

26 tools, one or several SendPulse accounts, and a read-only mode for people who should look but not send.

## What you need

- Node.js 18 or newer, and git (npm installs the server straight from this repo)
- SendPulse API credentials: **Settings > API > Client credentials** ([direct link](https://login.sendpulse.com/settings/api)). Copy the **ID** and the **Secret**.

The credentials open the **whole SendPulse account**, not one bot. Anyone holding them can message every contact in it. Keep them out of chats, screenshots and git.

## Install in Claude Code

### Windows

Two lines, in **Command Prompt** (search for `cmd` in the Start menu), not PowerShell:

```
npm install -g github:lieox/sendpulse-whatsapp-mcp
claude mcp add -e SENDPULSE_CLIENT_ID=your-id -e SENDPULSE_CLIENT_SECRET=your-secret -e SENDPULSE_READ_ONLY=1 -s user sendpulse cmd /c sendpulse-whatsapp-mcp
```

Why it looks like this:

- **Command Prompt, not PowerShell.** On many Windows machines PowerShell's execution policy blocks `npm` itself (`npm.ps1 cannot be loaded because running scripts is disabled on this system`). Command Prompt runs `npm.cmd` and is not affected. CI also passes in PowerShell, but only because scripts are allowed there.
- **Installed once, not through npx.** The install takes about 30 seconds on a Windows CI machine. Through npx that happens on the first start, Claude Code gives up after 30 seconds, and the first connection fails. An installed server starts instantly and needs no network to start.
- **No `--` in the command.** When Claude Code itself was installed with npm, PowerShell swallows `--` and the command fails with `error: unknown option '-y'`. Keep `-s user` right before the name: `-e` accepts several values and stops only at the next option.
- **`cmd /c`** is the safe form for npm commands on Windows. CI shows current Claude Code versions (2.1.197 and 2.1.284) also connect with plain `sendpulse-whatsapp-mcp`.

To update later, run the `npm install -g` line again.

### macOS

One line:

```bash
claude mcp add sendpulse -s user -e SENDPULSE_CLIENT_ID=your-id -e SENDPULSE_CLIENT_SECRET=your-secret -e SENDPULSE_READ_ONLY=1 -- npx -y github:lieox/sendpulse-whatsapp-mcp
```

### Then, on both

Restart Claude Code, run `/mcp`, and check that `sendpulse` shows as connected. Then ask: *"list my SendPulse bots"*.

Drop `-e SENDPULSE_READ_ONLY=1` when you want Claude to be able to send (remove the server first with `claude mcp remove sendpulse -s user`, then add it again).

### What CI checks

On every push, [GitHub Actions](.github/workflows/ci.yml) runs the commands above in a real Claude Code and requires `claude mcp get` to report **Connected**:

- Windows: PowerShell 7, Windows PowerShell 5.1 and Command Prompt, with Claude Code installed both natively and through npm
- macOS: zsh, with an empty npx cache (a true first run)

It also builds on both systems, checks that the committed `dist/` matches `src/`, and runs a smoke test of every mode against the real SendPulse API with fake credentials.

## Install in Claude Desktop

Not covered by CI.

Settings > Developer > Edit Config, then add:

```json
{
  "mcpServers": {
    "sendpulse": {
      "command": "npx",
      "args": ["-y", "github:lieox/sendpulse-whatsapp-mcp"],
      "env": {
        "SENDPULSE_CLIENT_ID": "your-id",
        "SENDPULSE_CLIENT_SECRET": "your-secret",
        "SENDPULSE_READ_ONLY": "1"
      }
    }
  }
}
```

Quit Claude Desktop completely and open it again.

## Configuration

| Variable | Meaning |
|---|---|
| `SENDPULSE_CLIENT_ID` + `SENDPULSE_CLIENT_SECRET` | One account. The tools use it automatically, no account name needed. |
| `SENDPULSE_ACCOUNTS` | Several accounts, as JSON: `{"brand_a":{"id":"...","secret":"..."},"brand_b":{...}}`. Every tool then takes an `account` argument. Ignored when the two variables above are set. |
| `SENDPULSE_READ_ONLY` | `1` exposes only the 10 read tools. Sending, tagging, flows and campaigns are not registered at all, so Claude cannot call them. |

## Tools

| Area | Read (always on) | Write (off in read-only mode) |
|---|---|---|
| Bots | `list_bots`, `get_bot_stats` | |
| Contacts | `get_contact`, `get_contacts_by_tag` | `create_contact`, `set_contact_name`, `set_contact_variable`, `set_contact_tags`, `remove_contact_tag`, `disable_contact`, `enable_contact`, `pause_contact_automation`, `resume_contact_automation` |
| Messages | `list_chats`, `get_chat_messages` | `send_message`, `send_template`, `send_template_by_phone` |
| Flows | `list_flows`, `list_triggers` | `run_flow`, `run_flow_by_trigger` |
| Campaigns | | `send_campaign`, `send_template_campaign` |
| Metadata | `list_tags`, `list_variables` | |

Every tool name starts with `sendpulse_`.

## Things WhatsApp enforces, not this server

- `send_message` only works within 24 hours of the contact's last message. Outside that window, use an approved template (`send_template`).
- Templates must be approved in Meta first, and Meta charges for template messages.
- `send_campaign` and `send_template_campaign` go to **every subscriber of the bot** unless you pass a `filter`. Ask Claude to show you the exact payload before it sends one.
- The SendPulse API allows 10 requests per second.

## Development

```bash
npm install
npm run compile    # compiles src/ to dist/
npm test           # smoke test, no credentials needed
npm run dev        # watch mode
```

`dist/` is committed on purpose, so installing from GitHub needs no build step. Recompile and commit it with every change to `src/` (CI fails if they differ).

The compile script is deliberately **not** named `build`: npm treats a git dependency with a `build` script as needing preparation, installs TypeScript and the other dev tools into every user's install, and the first start becomes too slow for Claude Code on Windows.
