About

Zoho Mail ships in the w6w first-party pack. It declares 16 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Zoho Mail puts a mailbox under workflow control, wired for every one of Zoho’s eight regional data centres. Message actions send new mail, search and list what has already arrived, read a message’s metadata, content or headers individually, mark messages read or unread, move them between folders, apply labels, and delete them. Folder and label actions create and list the organizational structures a mailbox uses to sort messages.

Because a Zoho account lives on exactly one of eight regional data centres — each with its own login and mail API host — the app offers a separate connection method per region, so a workflow author picks the one matching their account rather than hitting a host their account was never issued on. Account actions list and read the mailbox or mailboxes a connection can see, covering the case where one connection legitimately spans more than one.

This app is scoped specifically to Zoho Mail and is separate from this pack’s Zoho CRM integration, which is a different product with its own API surface entirely.

Build with Zoho Mail

Three routes to the same 16 actions. The Workflow tab is generated from Zoho Mail'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.

Get Account

account-get

Fetch the details of one mailbox account.

Get Accounts

account-list

List every mailbox account the authenticated user can see.

Create Folder

folder-create

Add a new folder to the mailbox.

Get Folders

folder-list

List every folder in the mailbox — Inbox, Sent, Trash, and any custom folders.

Create Label

label-create

Add a new label to the mailbox.

Get Labels

label-list

List every label defined in the mailbox.

Get Email Content

message-content-get

Fetch one email's body content.

Delete Email

message-delete

Delete one email — moved to Trash unless Permanently delete is on.

Get Email Metadata

message-get

Fetch one email's metadata (subject, addresses, size, status) without its body.

Get Email Headers

message-header-get

Fetch the internet message headers of one email.

Apply Label to Email

message-label-apply

Apply one or more labels to one or more emails.

List Emails

message-list

List emails in a folder, or filtered by status, flag, label or thread.

Mark Email Read/Unread

message-mark-read

Mark one or more emails as read or unread.

Move Email

message-move

Move one or more emails to a different folder.

Search Emails

message-search

Search emails using Zoho Mail's search syntax.

Send Email

message-send

Send an email, optionally scheduled for later.

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 Zoho Mail's real ids.

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 Zoho Mail, 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 Zoho Mail. 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: "folder-create",
  payload: {
    // accountId: "<value>",
    folderName: "<value>",
    // parentFolderId: "<value>",
  },
});

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

Give an AI agent Zoho Mail — without giving it Zoho Mail'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.zohomail#folder-create",
    "input": {
      "folderName": "<folderName>"
    }
  }
}

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 Zoho Mail 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

Zoho Mail'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. Zoho Mail itself is MIT, and the runtime that executes it is source-available (FSL).

Health checks

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