How to connect PDF Blocks 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 PDF Blocks 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 PDF Blocks in plain language.

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 PDF Blocks to Grok Bot

Once Grok Bot is set up, you connect PDF Blocks 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 PDF Blocks

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 PDF Blocks account

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

For example, ask it to:

• "Merge three PDFs and add watermark"
• "Split PDF into separate page files"
• "Protect PDF with password and permissions"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in your Grok bot, and your PDF Blocks 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 PDF Blocks through MCP without you sharing account credentials directly with the agent.

The PDF Blocks MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your PDF Blocks account. It provides structured and secure access to PDF document operations, so your agent can merge, split, watermark, secure, and reorganize PDFs on your behalf.

• PDF merging and splitting: Have your agent combine PDFs in a chosen order or split a document at a page, by page count, by custom page groups, or by file size.
• Page extraction and organization: Direct your agent to extract or remove selected pages, reorder them, reverse the full document, or repeat pages in a new PDF.
• Page rotation: Let the agent rotate all pages or selected pages by a supported multiple of 90 degrees.
• Text and image watermarks: Instruct your agent to add styled text or a PNG or JPEG watermark to every page or only selected pages.
• PDF security and permissions: Have your agent add or remove passwords, set or clear document permissions, and remove digital signatures and timestamps.

Way Forward

Now that PDF Blocks 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.
