How to connect Harvest to Grok Bot

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 Harvest 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 Harvest in plain language.

Composio exposes 1,500+ apps to your Grok bot through a single connection, so you get:

• Connect to 1,500+ 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 Harvest to Grok Bot

Once Grok Bot is set up, you connect Harvest 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 Harvest

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.

Add to Grok Bot

Grok Bot opens the Composio plugin, showing its connector and skills. Click Add.

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 Harvest account

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

For example, ask it to:

• "Create a new client for ACME Corp"
• "Log an expense for project 'Website Redesign'"
• "Generate an invoice for hours worked this week"

It will prompt you to authenticate and authorize access.

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

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 Harvest through MCP without you sharing account credentials directly with the agent.

The Harvest MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Harvest account. It provides structured and secure access to your time-tracking, invoicing, and project management data, so your agent can create clients, log expenses, send invoices, record payments, and manage estimates automatically on your behalf.

• Client and contact management: Seamlessly create new clients and add contacts to keep your client list up to date without manual entry.
• Estimate creation and communication: Automatically generate new estimates, categorize line items, and send estimate messages or updates to clients.
• Expense tracking automation: Log new expense entries against projects, ensuring accurate financial records and effortless cost tracking.
• Streamlined invoicing and payments: Create professional invoices, categorize invoice items, send invoice notifications, and record payments as soon as they happen.
• Project financial workflow optimization: Let your agent handle the full cycle—from creating clients to sending invoices and tracking payments—saving your team valuable time and reducing errors.

Way Forward

Now that Harvest 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.
