Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

file_system

Applies to the server that hosts this plugin, not to your machine.

HTTP Network Access

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

{
  "mcpServers": {
    "dev-chatrail-chatrail": {
      "url": "https://www.chatrail.dev/v1/mcp"
    }
  }
}

Documentation

From the project's GitHub README.

ChatRail MCP server

Operate a ChatRail workspace from Claude, Cursor, VS Code and any other Model Context Protocol client. Check the health of your WhatsApp connections, look up groups, trace why a message failed, manage scheduled messages and replay webhook deliveries without leaving your editor.

ChatRail is a WhatsApp API for developers: send and receive WhatsApp messages over HTTP from a number you already have. See the MCP documentation for the full reference.

Privacy by design

Message bodies, recipient phone numbers and credentials are never returned by any tool.
Tools that change state return a preview first and apply only when called again with confirm: true.
Every call is scoped to one workspace and recorded in its audit log.

Two ways to connect

1. Hosted server with OAuth (recommended)

Point any client that supports remote MCP servers at:

https://www.chatrail.dev/v1/mcp

Your client opens a browser window where a workspace owner, admin or developer approves access. Nothing to install and no key to copy.

Claude Code

claude mcp add --transport http chatrail https://www.chatrail.dev/v1/mcp

Cursor (~/.cursor/mcp.json)

{
  "mcpServers": {
    "chatrail": { "url": "https://www.chatrail.dev/v1/mcp" }
  }
}

VS Code (.vscode/mcp.json)

{
  "servers": {
    "chatrail": { "type": "http", "url": "https://www.chatrail.dev/v1/mcp" }
  }
}

2. Local stdio server with an API key

For clients that only run local servers, or when you would rather use an API key. This package runs on your machine and forwards requests to the hosted server.

In the ChatRail dashboard, create a workspace API key with the mcp:read scope. Add mcp:write if the assistant may reschedule, cancel, react or replay.
Add the server to your client.

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "chatrail": {
      "command": "npx",
      "args": ["-y", "chatrail-mcp"],
      "env": { "CHATRAIL_API_KEY": "cr_live_..." }
    }
  }
}

The package is published on npm as chatrail-mcp, so npx fetches it from the registry. If you need a version that is not published yet, run it straight from the repository instead:

"args": ["-y", "github:chatrail/chatrail_mcp"]

Docker

docker build -t chatrail-mcp .
docker run -i --rm -e CHATRAIL_API_KEY=cr_live_... chatrail-mcp

Variable	Required	Description
`CHATRAIL_API_KEY`	Yes, to call tools	Workspace API key with `mcp:read` (and optionally `mcp:write`).
`CHATRAIL_MCP_URL`	No	Override the endpoint. Defaults to `https://www.chatrail.dev/v1/mcp`.

Without a key the server still starts and lists its tools, so you can inspect it before signing up.

Tools

Tool	Scope	What it does
`list_connections`	read	Every WhatsApp connection in the workspace with its state and health.
`get_connection`	read	One connection with its state, health and recent state history.
`list_whatsapp_groups`	read	Groups visible to a connected number, with ids and participant counts.
`get_whatsapp_group`	read	Name, description, settings and member counts for one group.
`list_messages`	read	Recent messages with their delivery state.
`get_message`	read	One message and its delivery timeline.
`explain_message_failure`	read	A structured explanation of why a message failed.
`list_scheduled_messages`	read	Messages waiting to be sent, soonest first.
`list_webhook_deliveries`	read	Recent webhook deliveries and their outcomes.
`reschedule_message`	write	Change when a scheduled message is sent. Previews first.
`cancel_scheduled_message`	write	Cancel a message that has not been sent. Previews first.
`react_to_message`	write	Set or remove an emoji reaction on a message. Previews first.

Plans

MCP access is included on the ChatRail Core + AI and Team plans. See pricing.

Development

npm install
npm run build
