Set up Kabuken in Cursor

What you need

• A Kabuken account. Sign in or sign up.
• Cursor, which supports remote MCP servers over HTTP with OAuth.
• Sign-in method: OAuth is the default choice. Use a key when a sign-in window is not possible. Both use the same account and plan.

Sign in with OAuth

Add this to .cursor/mcp.json in your project, or to ~/.cursor/mcp.json for all projects:

{
  "mcpServers": {
    "kabuken": {
      "url": "https://kabuken.intellics.ai/mcp"
    }
  }
}

Open the Customize page in Cursor, find kabuken, and sign in. Cursor opens a browser window. Sign in to Kabuken, then select Authorize.

Use an API key

Create a kbk_ key on the Account page: in the API Access section, select Generate Key. Set it as the environment variable KABUKEN_API_KEY, start Cursor from that environment, and send it as a header:

{
  "mcpServers": {
    "kabuken": {
      "url": "https://kabuken.intellics.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${env:KABUKEN_API_KEY}"
      }
    }
  }
}

If your Cursor version does not expand ${env:...}, put the key itself in ~/.cursor/mcp.json (the user-level file, outside any repository) instead. Do not commit a file that holds the key itself.
