What is the Kernel MCP server?

Kernel MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Access Kernel's cloud-based browsers and app actions via MCP (remote HTTP + OAuth).

What you get

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

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

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once Kernel is connected, these are the calls the assistant has available:

  • manage_browsers — Create, update, list, get, and delete browser sessions, and read archived telemetry for active or deleted sessions. Supports headless/stealth modes
  • manage_profiles — Setup (with guided live browser session), search/list with pagination, get, and delete browser profiles for persisting cookies and logins
  • manage_projects — Create, list, get, update, and delete organization projects. Inspect and update per-project resource limits
  • manage_api_keys — Create, list, get, update, and delete org-wide or project-scoped API keys. Create returns the plaintext key once
  • manage_browser_pools — Create, list, get, delete, and flush pools of pre-warmed browsers. Acquire and release browsers from pools
  • manage_proxies — Create, list, get, check, and delete proxy configurations (datacenter, ISP, residential, mobile, custom)
  • manage_replays — Start, stop, and list MP4 video replay recordings for a browser session. Session-scoped: start once, run your automation, then stop. Requires a paid
  • manage_extensions — List and delete uploaded browser extensions
  • manage_apps — List/search apps, invoke actions, get/list/delete deployments, and get invocation results
  • manage_auth_connections — Create, list, get, delete managed auth connections; start login flows (returns a hosted URL and live view); submit MFA codes or SSO selections
  • manage_credentials — Create, list, get, update, and delete stored credentials; fetch a current TOTP code for credentials with a configured totp_secret
  • manage_credential_providers — Create, list, get, update, and delete external credential providers (e.g. 1Password); list available items and test the provider connection

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Kernel.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the kernel mcp server does with a few real requests.

Choosing this one

Among the browser automation options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Kernel's toolset — manage_browsers, manage_profiles, manage_projects and 11 more — is a fair guide to whether it matches your workflow. It is maintained by com.onkernel; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects Kernel to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (manage_browsers, manage_profiles, manage_projects, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Kernel directly.
