README

Kernel MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with secure access to Kernel platform tools and browser automation capabilities.

🌐 Use instantly at https://mcp.onkernel.com/mcp — no installation required!

What is this?

The Kernel MCP Server bridges AI assistants (like Claude, Cursor, or other MCP-compatible tools) with the Kernel platform, enabling them to:

🚀 Deploy and manage Kernel apps in the cloud
🌐 Launch and control headless Chromium sessions for web automation
📊 Monitor deployments and track invocations
🔍 Search Kernel documentation and inject context
💻 Execute arbitrary Playwright code against live browsers
🎥 Automatically record video replays of browser automation

Open-source & fully-managed — the complete codebase is available here, and we run the production instance so you don't need to deploy anything.

The server uses OAuth 2.0 authentication via Clerk to ensure secure access to your Kernel resources.

For a deeper dive into why and how we built this server, see our blog post: Introducing Kernel MCP Server.

Setup Instructions

General (Transports)

Streamable HTTP (recommended): https://mcp.onkernel.com/mcp
stdio via mcp-remote (for clients without remote MCP support): npx -y mcp-remote https://mcp.onkernel.com/mcp

Use the streamable HTTP endpoint where supported for increased reliability. If your client does not support remote MCP, use mcp-remote over stdio.

Kernel's server is a centrally hosted, authenticated remote MCP using OAuth 2.1 with dynamic client registration.

Quick Setup with Kernel CLI

The fastest way to configure the MCP server is using the Kernel CLI:

# Install the CLI
brew install onkernel/tap/kernel
# or: npm install -g @onkernel/cli

# Install MCP for your tool
kernel mcp install --target <target>

Supported Targets

Target	Command
Cursor	`kernel mcp install --target cursor`
Claude Desktop	`kernel mcp install --target claude`
Claude Code	`kernel mcp install --target claude-code`
VS Code	`kernel mcp install --target vscode`
Windsurf	`kernel mcp install --target windsurf`
Zed	`kernel mcp install --target zed`
Goose	`kernel mcp install --target goose`

The CLI automatically locates your tool's config file and adds the Kernel MCP server configuration.

Connect in your client

Claude

Our remote MCP server is not compatible with the method Free users of Claude use to add MCP servers.

Pro, Max, Team & Enterprise (Claude.ai and Claude Desktop)

Go to Settings → Connectors → Add custom connector.
Enter: Integration name: Kernel, Integration URL: https://mcp.onkernel.com/mcp, then click Add.
In Settings → Connectors, click Connect next to Kernel to launch OAuth and approve.
In chat, click Search and tools and enable the Kernel tools if needed.

On Claude for Work (Team/Enterprise), only Primary Owners or Owners can enable custom connectors for the org. After it's configured, each user still needs to go to Settings → Connectors and click Connect to authorize it for their account.
