Set up Kabuken in Claude Code

What you need

• A Kabuken account. Sign in or sign up.
• Claude Code, installed, and a terminal.
• Sign-in method: OAuth needs no secret in your shell history or config. Use a key for scripts and headless runs where no browser is available. Both use the same account and plan.

Sign in with OAuth

1. Run this command in your terminal:

   claude mcp add --transport http kabuken https://kabuken.intellics.ai/mcp

2. Inside Claude Code, run /mcp, select kabuken, and sign in. Select Authorize in the browser.

Use an API key

Create a kbk_ key on the Account page: in the API Access section, select Generate Key.

claude mcp add --transport http kabuken https://kabuken.intellics.ai/mcp --header "Authorization: Bearer <your API key>"

Replace <your API key> with your key. Keep it private. Anyone with your key can use your account.

First prompt

Who are the major shareholders of MUFG?

Troubleshooting

See Troubleshooting and Authentication.

• claude mcp list shows the configured servers. /mcp inside Claude Code shows their status, including servers that still need sign-in.
• claude mcp remove kabuken removes the server. For a remote server this also deletes the stored OAuth tokens.
