Troubleshooting: connection and sign-in

Find your problem below and follow the steps.

The Creator MCP tools don't appear
1. Check that Creator MCP is turned on in your app's MCP or connector settings.
2. Check that its tools are turned on for the current chat (in Claude: + → Connectors).
3. Reconnect to refresh the tool list.
4. Ask the AI: "List the Creator MCP tools."
You may see a set of tools that start with creator_. creator_preview only appears in Claude, ChatGPT, and other apps that support MCP Apps.

Only three tools appear (creator_exec, creator_docs, creator_document)? The server you're connected to doesn't offer downloads, file deletion, or workspace tools. Reconnecting won't fix it. Check that you used this exact address: https://creator.mcp.lottiefiles.com/mcp.

Can't add the server at all? Your organization may limit custom MCP servers. Check with your admin.
Sign-in doesn't open, gets stuck, or shows "401 Unauthorized"
1. Start the sign-in from your app's MCP or connector settings.
2. Finish both the LottieFiles login and the approval (consent) page.
3. For 401 Unauthorized, reconnect and sign in again.
4. If it still fails, remove Creator MCP from your app and add it again. Your app may be using an old saved registration.
Also check:
- Your app must support remote MCP with OAuth sign-in.
- If your app only supports local (stdio) MCP servers, use the bridge in the developer guide under Other clients.
- On a remote machine, use your app's browser sign-in method.
ChatGPT shows "unknown client_id"

The plugin was created with ChatGPT's default registration method (CIMD), which currently doesn't work. You can't change this setting after creating the plugin.
1. Go to Settings → Plugins and delete the Creator MCP plugin.
2. Add it again. In Advanced OAuth settings, set Registration method to Dynamic Client Registration (DCR).
See Connect your MCP client for the full steps.
The LottieFiles page says "consent expired"

The approval page only works for five minutes. Start the connection again from your connector or plugin, and select Approve right away.
A workspace tool asks me to sign in again

If you connected before workspace saves were available, you need to sign in once more the first time you use a workspace tool. Your other tools keep working.
1. Complete the sign-in when your app opens it.
2. Ask the AI: "Which LottieFiles account and workspace are you connected to?" to confirm.
If the sign-in doesn't open on its own, remove Creator MCP from your app and add it again. Reconnecting alone doesn't trigger a new sign-in.
My animations are missing

Your animations belong to the LottieFiles account you approved when you connected. If you reconnected while your browser was signed in to a different account, the AI now sees that account's animations instead.
1. Ask the AI: "Which LottieFiles account are you connected to?"
2. If it's the wrong account, sign in to the correct account in your browser, then remove and add Creator MCP again.
A Lottie Creator link says "Unauthorized"

Your browser is signed in to a different LottieFiles account from the one the AI saves to. Sign in to the correct account in your browser and open the link again. You don't need to reconnect Creator MCP.
The address doesn't work, or the server shows "503"
1. Check that you're using https://creator.mcp.lottiefiles.com/mcp exactly.
2. A 503 error can mean a short service problem. Wait a moment, then try again.
3. If it keeps happening, reconnect once the service is back.
4. If the problem continues, contact LottieFiles support.
