About

Telegram ships in the w6w first-party pack. It declares 21 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Telegram sends messages and media through a bot from a workflow — text, photos, video, audio, documents, animations, stickers and location, each as its own dedicated action rather than one generic send that has to guess at content type, plus chat actions like typing to make an automated reply feel less abrupt.

Messages can be edited, pinned, unpinned and deleted after sending, and inline-keyboard callback queries can be answered, which is what a bot needs to build an interactive flow rather than only broadcasting one-way. Chat management covers reading a chat or its member list, listing administrators, updating a group’s title or description, and leaving a chat the bot no longer needs to be in.

A fit for turning an external event into a Telegram notification, running a bot that responds to button presses, or managing group chats a bot administers as part of a larger workflow.

Build with Telegram

Three routes to the same 21 actions. The Workflow tab is generated from Telegram's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.

Answer Callback Query

callback-answer-query

Acknowledge an inline-keyboard button press, optionally showing a toast or alert.

Get Chat

chat-get

Fetch up-to-date information about a chat: title, description, photo, permissions.

Get Chat Administrators

chat-get-administrators

List the administrators of a chat. Returns every admin except other bots; in a channel with anonymous admins only the creator is returned.

Get Chat Member

chat-get-member

Get one member's status and rights in a chat. Useful for gating a workflow on membership.

Leave Chat

chat-leave

Remove the bot from a group, supergroup or channel.

Set Chat Description

chat-set-description

Change a chat's description. Requires the `can_change_info` admin right. Send an empty value to clear it.

Set Chat Title

chat-set-title

Rename a group, supergroup or channel. Requires the `can_change_info` admin right.

Get File

file-get

Resolve a Telegram `file_id` into its size and `file_path`. Links stay valid for at least an hour.

Delete Message

message-delete

Delete a message. Bots can delete their own messages, and any message in a group where they are an administrator.

Edit Message Text

message-edit

Replace the text of a message the bot previously sent.

Pin Message

message-pin

Pin a message in a chat. Requires the `can_pin_messages` admin right.

Send Message

message-send

Send a text message to a chat, group, supergroup or channel.

Send Animation

message-send-animation

Send a animation (GIF or soundless H.264 video) to a chat.

Send Audio

message-send-audio

Send a audio file, shown in Telegram's music player to a chat.

Send Chat Action

message-send-chat-action

Show a status indicator ('typing…', 'sending photo…') in a chat.

Send Document

message-send-document

Send a document (any file type) to a chat.

Send Location

message-send-location

Send a point on the map to a chat.

Send Photo

message-send-photo

Send a photo to a chat.

Send Sticker

message-send-sticker

Send a static .WEBP, animated .TGS or video .WEBM sticker.

Send Video

message-send-video

Send a video to a chat.

Unpin Message

message-unpin

Unpin a message. Omit the message ID to unpin the most recently pinned message.

A workflow step names the app and the action, and the editor fills in the connection when you pick one. This is the Step shape from the workflow spec, carrying Telegram's real ids.

+16 more actions available

Every app-specific value here is a blank you have to fill in. An app action is reached through the connection that authenticates it, so the address is a connection id, not the app id — and connections belong to your account, so a public page cannot know yours. Create one for Telegram, then fill in the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the parameters that action declares. The call itself is real — the shape is transcribed from the studio's own snippet builder, which prints the same kind of blanks — but nothing in it is specific to Telegram. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "message-send",
  payload: {
    chatId: "<value>",
    text: "<value>",
    // parseMode: "<value>",
    // disableWebPagePreview: "<value>",
    // delivery: "<value>",
  },
});

if (isActionRun(envelope)) console.log(envelope.value);
Install the CLI
npm install -g @w6w/cli
CLI
w6w run conn_YOUR_CONNECTION_ID --action message-send --payload '{"chatId":"<value>","text":"<value>"}'

Give an AI agent Telegram — without giving it Telegram's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.

One tool call
{
  "name": "w6w_invoke",
  "arguments": {
    "ref": "app:io.w6w.telegram#callback-answer-query",
    "input": {
      "callbackQueryId": "<callbackQueryId>"
    }
  }
}

Every tool names its target with a single ref. The app: form above doesn't name a connection at all — the host resolves which of the caller's Telegram connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.

A tool surface scoped to the caller

Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.

A durable workflow in one call

Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.

Health-aware discovery

Telegram's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.

The MCP surface is part of the hosted platform. Telegram itself is MIT, and the runtime that executes it is source-available (FSL).

Health checks

Telegram declares its own checks, so its health is a property of the app rather than something the host guesses at.
