[Questions](#faq) 1. ## Connect Claude Code Run this in a terminal: `claude mcp add --transport http kortex https://mcp.kortex-notebooklm.com/mcp`. Your browser opens a Kortex consent page.

[![The Agents page of the Kortex Workspace: access keys for Claude Desktop and Cursor with what each may do and when it was last used.](/media/features/agents.webp)](/media/features/agents.webp) Agents: one key for each AI app, and what each can do. 5. ## Connect Cursor Add this to `.cursor/mcp.json` in your project, or to `~/.cursor/mcp.json` for every project: a `kortex` entry under `mcpServers`. Set the address as `url`. Add a `headers` object whose `Authorization` is `Bearer` and your key. Then check **Settings**, **MCP** for a green light. 6. ## Connect Codex Add a `[mcp_servers.kortex]` block to `~/.codex/config.toml`. Set `command` to `npx`. Set `args` to `-y`, `mcp-remote`, the address, `--header` and `Authorization: Bearer` followed by your key. 7. ## Ask your first question With Chrome open and Kortex signed in, ask your assistant 'List my Gemini notebooks.' The first call after Chrome has been idle can take up to 30 seconds. ## If it doesn’t work Tools are listed but every call fails or times out Kortex needs Chrome running, with the extension on and signed in to the same account. A minimized window is fine. A quit Chrome is not. Ask your assistant to call get\_status. The first call is very slow Chrome pauses idle extensions, so Kortex can take up to 30 seconds to wake. Later calls are fast. If your client has a short tool timeout, raise it to at least 60 seconds. The assistant says a tool does not exist The key's profile hides it. A Read-only key does not show write tools. Make a Standard key if the assistant needs to make changes. Claude Desktop or Codex shows no Kortex tools These use npx mcp-remote, so you must install Node.js. Check the JSON or TOML for a typo. Then fully quit and reopen the app. I lost my key Kortex shows a key once and stores only a hash of it. Revoke it on the Agents page and generate a new one. ## Questions people ask Something we missed? [Ask us](#contact). ### Do I need a Kortex account? Yes. You sign in with your Kortex account. Claude Code, Claude Desktop, Claude on the web and ChatGPT connect through the browser. Cursor and Codex use a key. ### Do I need an API key? Not for Claude Code, Claude Desktop, Claude on the web or ChatGPT. They sign in with OAuth (a sign-in through your browser). Cursor and Codex use a key. So does any setup with no browser. ### Which key profile should I pick? Start with Read-only, the default. Use Standard for renames and moves. Full includes deletes, so use it only when you are watching. ### Can I keep Claude from deleting things? Yes. In Claude's connector settings you can set a tool to ask every time, or to never run. A Read-only or Standard key never allows deletes.
