MCP assistants

Grok

Grok connects to Lymi as a custom connector and signs in with OAuth. It needs a client ID, which Lymi publishes for it, because Lymi does not let apps register themselves.

MCP server URL
https://my.lymi.app/mcp

On a team account, an admin may need to enable the connector first. Once connected, ask Grok to add the cards from a lesson, list what is due, or find a card. What it can and cannot do is on Connect an assistant.

Grok

  1. Add the connector

    Open grok.com/connectors, press New Connector, choose Custom, and paste the server URL above.

  2. Give it Lymi’s client ID

    Grok asks for OAuth credentials. Paste this as the Client ID, leave Client Secret empty, choose None / PKCE only, and keep the endpoints Grok filled in.

    Client ID
    https://lymi.app/oauth/grok.json

  3. Sign in

    Press Save & Connect. Your browser opens on Lymi. Sign in with the account your Lymi uses, then approve the connection. Untick write if you want Grok to read your decks and nothing more.

When it does not connect

  • “Invalid redirect URI”. Grok signed in from a callback address Lymi does not list. Write to hello@lymi.app with the callback address in the error so it can be checked. Do not send a token or the full sign-in URL.
  • Grok never asks for a client ID. It tried to register itself and Lymi refused. Remove the connector and add it again; the credentials step follows the refusal.
