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
- 💻 Evaluate JavaScript and stream DOM snapshots
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.
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.

Troubleshooting
- Cursor clean reset: ⌘/Ctrl Shift P → run
Cursor: Clear All MCP Tokens
(resets all MCP servers and auth; re-enable Kernel and re-authenticate). - Clear saved auth and retry:
rm -rf ~/.mcp-auth
- Ensure a recent Node.js version when using
npx mcp-remote
- If behind strict networks, try stdio via
mcp-remote
, or explicitly set the transport your client supports
