Introduction

Grok is xAI's assistant, and its bot builder lets you create a personal agent that holds context, runs skills, and connects to the apps you already use through plugins.

This guide explains how to connect Nylas to a Grok bot using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a plugin, authenticate once, then ask your bot to work with Nylas in plain language.

Why use Composio?

Composio exposes 1,700+ apps to your Grok bot through a single connection, so you get:

  • Connect to 1,700+ apps with on-demand tool loading, so you do not fill your context window with unnecessary tool definitions.
  • Use programmatic tool calling through a remote workbench, letting the model write its own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
  • Handle large tool responses outside the model context to keep conversations lean.

Connecting Nylas to Grok Bot

Once Grok Bot is set up, you connect Nylas entirely from its interface, and the whole flow takes under a minute.

Set up Grok Bot

Get access. Grok Bot is included with Cursor Ultra, Cursor Premium Teams, and SuperGrok Heavy. Get the desktop app for macOS or Windows from x.ai/bot and sign in. An iPhone companion app is also available, and your bots sync across devices.

Create a bot. Pick a suggested role or define your own, then give it a short name, one primary job, and a short description of how it should work. Focused bots work best, because a clear role gives the bot more useful context over time.

Connect Nylas

1. Add the Composio plugin

Click the button. The Composio listing on x.ai opens and launches Grok Bot for you. If the app does not open on its own, click Add to Grok Bot.

2. Authenticate

Go to the Installed section and click the Composio entry. You'll see its connector and skills listed.

Click Authenticate. You'll be taken to the Composio consent screen. Review the access it requests and click Authorize. Composio handles the OAuth handshake for you, so you never touch API keys or tokens.

3. Connect your Nylas account

Back in the chat, ask your bot to connect to Nylas or give it any Nylas task.

For example, ask it to:

  • "Summarize unread emails from this morning"
  • "Create draft replies to urgent messages"
  • "Schedule meetings from email threads"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in your Grok bot, and your Nylas account is ready to use.

What is Grok Bot?

Grok is xAI's assistant, available as a chat interface and a bot builder for creating personal agents that run skills and connect to external apps.

With Composio Connect, your Grok bot can securely access apps like Nylas through MCP without you sharing account credentials directly with the agent.

What is the Nylas MCP server, and what's possible with it?

The Nylas MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Nylas account. It provides structured and secure access to your email, calendars, contacts, and Notetaker workflows, so your agent can search messages, manage drafts, send email, organize events, and coordinate meeting notes on your behalf.

  • Email search and retrieval: Instruct your agent to search messages and threads, read full emails, browse folders, and download specific attachments.
  • Drafting and sending email: Have your agent create, update, delete, and send drafts, or confirm and send new messages immediately.
  • Calendar and availability management: Let the agent check calendars and availability, list upcoming events, and create, update, or delete meetings.
  • Contact lookup: Direct your agent to browse your contacts, retrieve a specific contact, or find the Nylas grant linked to an email address.
  • Meeting Notetaker workflows: Have your agent schedule or send a Notetaker to Google Meet, Microsoft Teams, or Zoom, then retrieve its details, transcript, and media.

Way Forward

Now that Nylas is connected, extend your setup by connecting the other apps you already use every day, so your Grok bot can run true cross-app workflows end to end.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, your bot can coordinate multiple tools safely and reliably in one conversation.

FAQ

Frequently asked questions

With a standalone Nylas MCP server, the agents and LLMs can only access a fixed set of Nylas tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Nylas and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Grok Bot fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Nylas tools.

Yes, absolutely. You can configure which Nylas scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Nylas data and credentials are handled as safely as possible.
