## Introduction

### How to connect Kernel MCP with ChatGPT
[ChatGPT](https://chatgpt.com/) can take action across your apps and files, stay with a project for hours, and turn a goal into finished materials like sheets, slides, and docs, not just answers.
In this guide, I will explain the easiest and most secure way to connect your Kernel account to ChatGPT via Composio Connect, so it can launch cloud browsers, run Playwright tasks, replay sessions, and manage browser profiles through natural language commands without ever putting your account credentials at risk.

## Also integrate Kernel with

- [Claude Cowork](https://composio.dev/toolkits/kernel/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/kernel/framework/hermes-agent)
- [Atomic Agent](https://composio.dev/toolkits/kernel/framework/atomic-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's Kernel integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
- 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect Kernel to ChatGPT

### Prerequisites
- A ChatGPT account. We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), and the steps are the same on the web.
- Access to the Kernel workspace you want to connect.
- [Composio plugin](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect Kernel to ChatGPT
### 1. Install the Composio plugin
Click the button. ChatGPT opens the Composio plugin page. Click Install plugin.
[Install in ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a58503580c08191b78cc5bdaf4eba6e)
You can also find it inside ChatGPT: go to Settings, open Plugins, search the marketplace for Composio, and click Install plugin.
### 2. Authenticate
After you install, ChatGPT asks you to authenticate with Composio. Log in and click Allow access to authorize ChatGPT to use your Composio account.
### 3. Start using Composio
That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread Kernel messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize Kernel.
### Option 2: Add Composio as an MCP server
If you cannot use the plugin marketplace, add Composio as a custom MCP server instead.
### 1. Open the MCP settings
In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

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

The Kernel MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kernel account. It provides structured and secure access to cloud browsers, persistent profiles, computer controls, Playwright execution, browser network requests, screenshots, and session replays, so your agent can create browser sessions, interact with websites, run Playwright workflows, preserve browser state, and record sessions on your behalf.
- Cloud browser control: Have your agent create, update, inspect, and delete browser sessions, then click, scroll, type text, press keys, move the mouse, and capture screenshots.
- Playwright browser automation: Direct your agent to run JavaScript or TypeScript with Playwright to navigate pages, interact with forms, submit actions, and automate browser workflows.
- Persistent browser profiles: Let the agent create, save, download, rename, list, and delete browser profiles so browser state can be reused across sessions.
- Authenticated browser requests: Instruct your agent to send read-only or state-changing HTTP requests through a browser while using its cookies, headers, TLS fingerprint, and proxy settings.
- Session recording and extensions: Have your agent start and stop browser replays, list and retrieve recordings, and upload unpacked Chromium extensions to a running browser.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `KERNEL_BATCH_COMPUTER_ACTIONS` | Batch Computer Actions | Execute 1-100 computer actions sequentially in a Kernel browser, stopping on the first error. Actions can click, type, press keys, and submit forms or cause other irreversible external effects. |
| `KERNEL_BROWSER_CURL` | Browser Curl | Send a read-only GET, HEAD, or OPTIONS request through a Kernel browser's network stack, inheriting its cookies, TLS fingerprint, proxy settings, and default headers. For POST, PUT, PATCH, or DELETE, use Browser HTTP Request. |
| `KERNEL_BROWSER_HTTP_REQUEST` | Browser HTTP Request | Send a state-changing POST, PUT, PATCH, or DELETE request through a Kernel browser's network stack, inheriting its cookies, TLS fingerprint, proxy settings, and default headers. The target may change external systems irreversibly. For GET, HEAD, or OPTIONS, use Browser Curl. |
| `KERNEL_CLICK` | Click | Click at browser viewport coordinates with an optional mouse button, click phase, modifiers, and repetition count. A click can submit forms, place orders, or cause other irreversible external effects. |
| `KERNEL_CREATE_BROWSER` | Create Browser | Create a Kernel browser session; defaults to a headless browser with a 60-second inactivity timeout. |
| `KERNEL_CREATE_PROFILE` | Create Profile | Create an empty persistent browser profile, optionally with a unique name, for reuse by later browser sessions. |
| `KERNEL_DELETE_BROWSER` | Delete Browser | Permanently end and delete a Kernel browser session by ID or name. |
| `KERNEL_DELETE_PLAYWRIGHT_EXECUTOR` | Delete Playwright Executor | Stop and permanently delete a named, non-default Playwright executor from a Kernel browser. Its running call fails, its name can be reused, and close_tab controls whether its tab is also closed. To restart the reserved default executor, use Restart Default Playwright Executor. |
| `KERNEL_DELETE_PROFILE` | Delete Profile | Permanently delete a browser profile by ID or name. |
| `KERNEL_DOWNLOAD_PROFILE` | Download Profile | Download a profile's stored browser state. Current profiles return the requested tar.zst or uncompressed tar format; legacy profiles may return JSON regardless of the requested format. The profile must have captured state from a browser session. |
| `KERNEL_DRAG_MOUSE` | Drag Mouse | Drag a mouse button through an ordered path of browser viewport coordinates, with optional timing, linear-step, and modifier controls. A drag can move items, submit controls, or cause other irreversible external effects. |
| `KERNEL_EXECUTE_PLAYWRIGHT` | Execute Playwright | Execute arbitrary TypeScript or JavaScript with Playwright access to the browser; the code may navigate, mutate pages, submit forms, or cause irreversible external effects. |
| `KERNEL_GET_BROWSER` | Get Browser | Get safe operational details for one browser session by ID or name, optionally including a deleted session. |
| `KERNEL_GET_MOUSE_POSITION` | Get Mouse Position | Get the current mouse cursor coordinates in a Kernel browser session. |
| `KERNEL_GET_PROFILE` | Get Profile | Get one browser profile by its ID or exact name. |
| `KERNEL_GET_REPLAY` | Get Replay | Download a completed browser replay as MP4. If the replay is still processing, the action asks the caller to retry later. |
| `KERNEL_LIST_BROWSERS` | List Browsers | List browser sessions, optionally filtered by lifecycle state, search text, tags, or region, one offset page at a time. |
| `KERNEL_LIST_PLAYWRIGHT_EXECUTORS` | List Playwright Executors | List the default and named Playwright executors for a Kernel browser, including whether each is busy and its owned tab when available. |
| `KERNEL_LIST_PROFILES` | List Profiles | List browser profiles, optionally filtered by substring or exact name, one offset page at a time. |
| `KERNEL_LIST_REPLAYS` | List Replays | List replay recordings for a headful browser session without returning signed viewer URLs. |
| `KERNEL_MOVE_MOUSE` | Move Mouse | Move the cursor to browser viewport coordinates, optionally using a timed human-like path and held modifier keys. |
| `KERNEL_PRESS_KEY` | Press Key | Press an ordered sequence of X11 keys or key chords in a browser, optionally holding modifiers or holding the sequence for a duration. Key presses may submit forms, activate controls, or trigger other irreversible external effects. |
| `KERNEL_READ_CLIPBOARD` | Read Clipboard | Read the current text from a Kernel browser session's clipboard. |
| `KERNEL_RENAME_PROFILE` | Rename Profile | Rename a Kernel browser profile by ID or exact name. Rename profiles only when they are not in use because sessions referencing the old name may fail to save their changes. |
| `KERNEL_RESTART_DEFAULT_PLAYWRIGHT_EXECUTOR` | Restart Default Playwright Executor | Restart a Kernel browser's reserved default Playwright executor. Its process is stopped and any running call fails irreversibly; queued and later calls run on the new process. This does not delete a named executor or close a tab. |
| `KERNEL_SAVE_BROWSER_PROFILE` | Save Browser Profile | Save a running browser's current state to exactly one destination profile ID or name, creating a named profile when needed and overwriting an existing destination. This restarts the browser, closes all active connections, reloads pages, and loses in-memory page state; reconnect after completion. It does not attach the profile or enable save_changes. |
| `KERNEL_SCROLL` | Scroll | Scroll horizontally or vertically at browser viewport coordinates, optionally while holding modifier keys. |
| `KERNEL_SET_CURSOR_VISIBILITY` | Set Cursor Visibility | Hide or show the cursor in a Kernel browser session. |
| `KERNEL_START_REPLAY` | Start Replay | Start recording a headful Kernel browser session and return its replay identifier and recording metadata without exposing its signed viewer URL. |
| `KERNEL_STOP_REPLAY` | Stop Replay | Stop an active replay recording for a Kernel browser identified by ID or name. |
| `KERNEL_TAKE_SCREENSHOT` | Take Screenshot | Capture the full browser viewport or a rectangular region as a PNG download. |
| `KERNEL_TYPE_TEXT` | Type Text | Type text into the currently focused browser element with an optional per-keystroke delay. |
| `KERNEL_UPDATE_BROWSER` | Update Browser | Update mutable settings on an existing Kernel browser session. |
| `KERNEL_UPLOAD_BROWSER_EXTENSIONS` | Upload Browser Extensions | Upload and activate one or more unpacked Chromium extension ZIP archives in an existing running browser. This ad-hoc operation does not add extensions to Kernel's reusable extension catalog. Chromium may restart, disrupting active browser connections. |
| `KERNEL_WRITE_CLIPBOARD` | Write Clipboard | Write text to the system clipboard of a Kernel browser session. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Kernel MCP?

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

### Can I use Tool Router MCP with ChatGPT?

Yes, you can. ChatGPT 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 Kernel tools.

### Can I manage the permissions and scopes for Kernel while using Tool Router?

Yes, absolutely. You can configure which Kernel 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.

### How safe is my data with Composio Tool Router?

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 Kernel data and credentials are handled as safely as possible.
