Kernel Mcp Server
Give Claude Code or Cursor a remote cloud browser and app actions without running Chrome locally.
Overview
Kernel MCP Server is a MCP server for the Build phase that exposes OnKernel cloud browsers and app actions to AI agents over remote HTTP with OAuth.
What is this MCP server?
- Remote MCP endpoint at mcp.onkernel.com over streamable-http
- OAuth-backed access to Kernel cloud browsers
- App actions callable from the agent without local browser infra
- GitHub source at onkernel/kernel-mcp-server for self-audit of the server definition
- Published server version 1.0.0 in the MCP server manifest
- One streamable-http remote URL: https://mcp.onkernel.com/mcp
- Source repository: github.com/onkernel/kernel-mcp-server
Community signal: 30 GitHub stars.
What problem does it solve?
Local browser automation breaks in CI and on laptops, leaving agents unable to reliably click, scrape, or exercise web UIs.
Who is it for?
Solo builders shipping agent features that need real browser interaction without maintaining headless Chrome infrastructure.
Skip if: Teams that only need static API calls with no DOM interaction, or who cannot use OAuth remotes in their MCP client.
What do I get? / Deliverables
After you add the remote MCP URL and OAuth, your agent can run cloud browser sessions and app actions as first-class tools.
- Registered remote MCP server com.onkernel/kernel-mcp-server in your agent client
- Agent-callable cloud browser and app-action tools after OAuth
Recommended MCP Servers
Journey fit
Canonical shelf is Build because the primary job is wiring an agent to external runtime tooling via MCP. Integrations is the right subphase for streamable-http remotes that expose browser and app-action APIs to the agent.
How it compares
MCP browser-runtime integration, not a local Playwright skill or a generic web-search plugin.
Common Questions / FAQ
Who is Kernel MCP Server for?
Indie and solo developers using Claude Code, Cursor, or other MCP clients who want cloud browsers and app actions instead of local automation stacks.
When should I use Kernel MCP Server?
Use it when you are building or testing agent workflows that must open pages, interact with UIs, or trigger hosted app actions during validate prototypes, build integrations, or ship-side test passes.
How do I add Kernel MCP Server to my agent?
Add the streamable-http remote https://mcp.onkernel.com/mcp in your MCP client configuration, complete OAuth as prompted, and restart the client so tools from com.onkernel/kernel-mcp-server load.
