What the publisher says

From the ChatRail repository's README, as published. We do not edit it. Read it on GitHub

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

confirm: true.

  • 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
  • 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.

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

}

Docker

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

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