JetAPI MCP Server

[npm] [CI] [MCP Registry] [License: MIT]

Official MCP server for JetAPI — send WhatsApp, Telegram, SMS and MAX messages, files and bulk mailings from AI agents like Claude, Cursor and VS Code.

Tools

Get a token

Sign up at jetapi.io and copy the API token from the dashboard. To send through WhatsApp or Telegram, connect the messenger in the dashboard first.

Installation

Claude Desktop — one click

1. Download jetapi-mcp-server.mcpb from the latest release.
2. Double-click it (or drag it into Claude Desktop → Settings → Extensions).
3. Paste your JetAPI token when asked. It is stored securely by Claude Desktop.

Claude Desktop — config file

Requires Node.js 18.17 or newer. Open Settings → Developer → Edit Config (claude_desktop_config.json) and add:

{  "mcpServers": {    "jetapi": {      "command": "npx",      "args": ["-y", "jetapi-mcp-server"],      "env": { "JETAPI_TOKEN": "your_token_here" }    }  }}

Restart Claude Desktop.

Claude Code

claude mcp add jetapi -- npx -y jetapi-mcp-server

The server needs JETAPI_TOKEN, so pass it when adding:

claude mcp add jetapi --env JETAPI_TOKEN=your_token_here -- npx -y jetapi-mcp-server

Cursor

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{  "mcpServers": {    "jetapi": {      "command": "npx",      "args": ["-y", "jetapi-mcp-server"],      "env": { "JETAPI_TOKEN": "your_token_here" }    }  }}

VS Code

Add to .vscode/mcp.json — VS Code will prompt for the token and keep it out of the file:

{  "inputs": [    { "type": "promptString", "id": "jetapi_token", "description": "JetAPI token", "password": true }  ],  "servers": {    "jetapi": {      "type": "stdio",      "command": "npx",      "args": ["-y", "jetapi-mcp-server"],      "env": { "JETAPI_TOKEN": "${input:jetapi_token}" }    }  }}

MCP Registry

The server is listed in the official MCP Registry as io.github.jetapi/jetapi-mcp-server, so clients and catalogs that read the registry can install it directly.

Other MCP clients

Any client that supports stdio servers:

{  "command": "npx",  "args": ["-y", "jetapi-mcp-server"],  "env": { "JETAPI_TOKEN": "your_token_here" }}

Configuration

Channels

dispatch_routing is an ordered list of channels. JetAPI tries them one by one and moves to the next channel only if delivery through the previous one fails. Without it, the default routing from your JetAPI dashboard is used.

Usage examples

Ask Claude in plain language:

Behaviour

• Parameters are sent as URL query parameters, as the JetAPI API expects; send_file uploads the file as multipart/form-data.
• Incompatible parameters (e.g. a Telegram username without the tdlib channel, or scheduled_at in the past) are rejected before any request is sent.
• HTTP 429 is retried up to 3 times with exponential backoff, honouring Retry-After.
• 5xx responses are retried twice after 1 s — except for requests that send messages or create webhooks (send_message, send_bulk, send_file, create_webhook), so nothing is sent twice.
• Requests time out after 30 seconds.
• Errors are returned as readable tool errors, e.g. Invalid JetAPI token. Check your JETAPI_TOKEN. or Validation error: text: the text cannot be empty.
• All logs go to stderr; stdout is reserved for the MCP protocol.

Development

git clone https://github.com/jetapi/jetapi-mcp-server.gitcd jetapi-mcp-servernpm installcp .env.example .env   # put your token in .envnpm run buildnpm start

Releasing

1. Bump the version in package.json, server.json (both version fields) and manifest.json, and add a CHANGELOG.md entry.
2. Merge to main, then push a tag: git tag v1.2.3 && git push origin v1.2.3.
3. The Release workflow publishes to npm (trusted publishing with provenance), creates a GitHub release with the .mcpb bundle and updates the MCP Registry.

Privacy Policy

The extension runs locally, collects no analytics or telemetry, and sends data only to the JetAPI API to perform the actions you request. Your API token is stored by your MCP client (Claude Desktop keeps it in secure storage).
