Add SuperEbook to Claude Code. One command, then write from your terminal.

1. 1

   Add the server.

   Run this once in your terminal:

   Copy the Claude Code command

   claude mcp add --transport http superebook https://www.superebook.ai/api/mcp

   That adds it to the project you’re in. To have it in every project, add --scope user after the name:

   Copy the command for every project

   claude mcp add --transport http superebook --scope user https://www.superebook.ai/api/mcp

2. 2

   Sign in.

   In Claude Code, type /mcp, pick superebook and choose Authenticate. Your browser opens SuperEbook’s page: sign in if it asks, check that it names Claude Code and says you’ll go back to localhost, then choose Allow.

3. 3

   Check it’s connected.

   claude mcp list shows superebook and whether it’s connected, and so does /mcp inside Claude Code.

On a computer with no browser to sign in from, such as a server or an SSH session, use a key instead.

1. 1

   Create a key.

   In SuperEbook, open Settings → Connect apps and choose Create API key. Name it after the computer, then copy it: you see the whole key only once.

2. 2

   Add the server with it.

   Copy the Claude Code command with a key

   claude mcp add --transport http superebook https://www.superebook.ai/api/mcp --header "Authorization: Bearer YOUR_KEY"

   Replace YOUR_KEY with your key.

• Claude Code saves a server added for you or for one project, key included, in ~/.claude.json on your computer. Keep that file to yourself.
• Don’t add a key with --scope project: project servers are saved in .mcp.json, which everyone on the project shares.

Claude Code can read the files in your project, so you can write a book from notes on disk: it passes up to 100,000 characters a book to SuperEbook as your material. Add longer files in SuperEbook itself.

• “Read notes/webinar.md and use SuperEbook to turn it into a lead magnet. Show me the plan first.”
• “List my SuperEbook books and check how far the newest one has got.”
• “What would a course companion cost in SuperEbook credits?”

Claude Code signs in as the same app on every computer, and a new sign-in replaces the last one: sign in on a second computer and the first is signed out. To use Claude Code on several computers at once, give each its own API key.

claude mcp remove superebook

That removes the server and the sign-in Claude Code kept for it. To end the connection on SuperEbook’s side at once, disconnect it in Settings → Connect apps too.

To sign in again without removing it, open /mcp, choose Clear authentication, then Authenticate.

/mcp shows superebook isn’t signed in

Choose Authenticate again. It happens after you disconnect it in Settings, after 30 days unused, or after Claude Code signs in on another computer.

It can’t connect with a key

Check that the whole key follows “Bearer ” in the header, and that it isn’t revoked in Settings → Connect apps. A revoked key stops at once; make a new one.

The browser page says “This link doesn’t work”

Run /mcp, pick superebook and choose Authenticate again: a sign-in link works once, within 30 minutes.

“You can have 5 keys.”

Revoke a key you no longer use in Settings → Connect apps, then create another.
