Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "max-messenger": {
      "command": "npx",
      "args": [
        "-y",
        "@woyax/mcp-max-messenger"
      ],

        "MAX_TOKEN": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add max-messenger --env MAX_TOKEN=your-value -- npx -y @woyax/mcp-max-messenger

Fill in the empty values before running it.

Open in Cursor

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "max-messenger": {
      "command": "npx",
      "args": [
        "-y",
        "@woyax/mcp-max-messenger"
      ],

Common questions

Is Max Messenger safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MAX_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.2) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Remote HTTP mode

Architecture

Two independent layers — tools work identically in both modes:

src/

├── core/ # Business logic — shared between modes │ ├── max-client.ts # MAX API HTTP client │ ├── types.ts # TypeScript types for MAX API │ └── tools/ │ ├── bot.ts # get_bot_info │ ├── chats.ts # get_chats, get_chat, edit_chat, send_action │ ├── messages.ts # send/get/edit/delete/pin/unpin, send_media │ ├── members.ts # get_chat_members, get_admins, set/remove_admin, add/remove_members │ └── updates.ts # get_updates, answer_callback ├── transports/ # Transport layer — selected at runtime │ ├── stdio.ts # Local mode (Claude Desktop, Cursor) │ └── http.ts # Remote mode (Streamable HTTP) └── index.ts # Entry point: transport selection

MAX API Notes

Authorization: Token passed as Authorization: — no `Bearer` prefix
Base URL: https://platform-api.max.ru
Rate limit: 30 requests/second
Group chats: GET /chats returns group chats only
Personal dialogs: Accessible via get_updates — use the returned chat_id with all standard tools
Media upload: Two-step process (upload → send). Audio/video tokens come from the upload step, not the file transfer
HTTP transport: Uses Streamable HTTP (SSE deprecated since MCP SDK 1.10.0)

Known MAX API Issues

remove_admin may return success: true without actually revoking rights — confirmed bug on MAX side
open_app button type returns "Field 'webApp' cannot be null" — MAX API bug
add_members may fail with add.participant.privacy if the user has privacy mode enabled

Roadmap

HTTP mode testing on VPS with n8n integration
Hosted MCP service (connect by URL, no local install)
Webhook support for real-time event handling
answer_callback testing via n8n webhook workflow
