## Introduction

### How to integrate Zoho mail MCP with Grok Build
[Grok Build](https://docs.x.ai/build/overview) is xAI's terminal coding agent. It runs on Grok 4.5, plans its work before it acts, and can run multiple sub-agents in parallel. It also reads Claude Code's MCP configuration, so any server you already have in a .mcp.json is picked up with no changes.
In this guide, I will show you how to connect your Zoho mail account to Grok Build through Composio, so it can send a follow-up email to yesterday's meeting attendees, list unread emails from your manager, schedule a calendar event from an email, and more without leaving the terminal. Composio holds the OAuth tokens for you, and Grok Build only calls the tools you approve.

## TL;DR

### Why use Composio over a standalone MCP server?
- Read and write access. Composio's Zoho mail integration lets Grok Build take real actions like creating drafts, sending updates, and labeling records, not just reading data.
- 1,000+ SaaS toolkits out of the box. One endpoint gives you a full catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Wire up a single Composio server instead of maintaining a separate MCP entry for each app.
- Smart, context-aware tool loading. Grok Build caps how many tools it holds in a single request. Composio loads only the tools a task needs, so you do not spend that budget on tools you are not using.
- Cross-app automation. Chain actions across apps in one run. Pull a thread, summarize it in Notion, and post the highlights to Slack from a single prompt.

## Connect Zoho mail to Grok Build

### Prerequisites
- Grok Build installed and signed in. Install with curl -fsSL https://x.ai/cli/install.sh | bash on macOS or Linux, or irm https://x.ai/cli/install.ps1 | iex on Windows PowerShell. On first launch Grok opens a browser to authenticate; for headless or CI use, set an XAI_API_KEY environment variable instead (create the key at [console.x.ai](https://console.x.ai/)).
- Access to the Zoho mail account you want to connect.
- The [Composio MCP endpoint](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=grok-build&utm_content=composio_connect). Composio's server is remote and hosted, so there is nothing to run locally and no tunnel to set up.
### Step-by-step: Connect Zoho mail to Grok Build
### 1. Install and verify Grok Build
Install the CLI, then restart your shell so the grok binary lands on your PATH:

```bash
curl -fsSL https://x.ai/cli/install.sh | bash
which grok
```

## What is the Zoho mail MCP server, and what's possible with it?

The Zoho mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zoho mail account. It provides structured and secure access to your mailbox, so your agent can perform actions like searching emails, sending messages, managing folders, organizing conversations, and handling attachments on your behalf.
- Smart email search and filtering: Ask your agent to find emails based on sender, subject, keywords, or date ranges for quick information retrieval.
- Automated composing and sending: Let your agent draft and send new emails, reply to existing threads, or create message templates to streamline communication.
- Folder and label organization: Have your agent organize your inbox by moving messages to folders, applying tags, or archiving threads for a clutter-free workspace.
- Attachment management: Retrieve, download, or send attachments through your agent—making file sharing and access seamless within your email workflow.
- Bulk message actions: Instruct your agent to mark emails as read or unread, star important messages, or clean up your inbox by deleting or archiving in bulk.

## Frequently Asked Questions

### What is the difference between the Composio Tool Router and a standalone Zoho mail MCP server?

A standalone Zoho mail MCP server gives Grok Build a fixed set of Zoho mail tools tied to that one server. The Composio Tool Router lets Grok Build load tools from Zoho mail and many other apps on demand, based on the task, all through a single endpoint.

### Does Grok Build support MCP?

Yes. Grok Build ships with native MCP support. Add a server with the grok mcp add command, from the in-session /mcps modal, or by editing ~/.grok/config.toml. It also reads Claude Code-style .mcp.json files, so Grok Build discovers the tools automatically.

### Can I reuse the same MCP config I already use with Claude Code?

Yes. Grok Build has zero-migration compatibility with Claude Code's configuration, so the same Composio server entry works in both without edits.

### How safe is my Zoho mail data with Composio?

Tokens, keys, and configuration are encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant, so your Zoho mail data and credentials are handled to that standard.
