Connect your MCP client

Add Creator MCP to Claude, ChatGPT, or a developer tool and sign in with your LottieFiles account.

You only need to connect once. Choose the steps for your AI app below.

Server address: https://creator.mcp.lottiefiles.com/mcp

Important: The LottieFiles approval page expires after five minutes. If you see "consent expired", start the connection again and approve right away.

Claude (web and desktop app)

Setup takes about two minutes. You don't need to install anything.

  1. Open Connectors. In Claude, go to Customize → Connectors. Select + Add, then Add custom connector.
  2. Enter the server details. Enter Creator MCP as the name. Paste the server address https://creator.mcp.lottiefiles.com/mcp, then select Continue.
  3. Keep the sign-in settings. Claude detects how the server signs you in. Keep Sign in now and Use Claude's published identity. Continue, then select Add.
  4. Approve access on LottieFiles. If Claude shows a Connect button, select it. On the LottieFiles approval page:
    • Check that the application is Claude.
    • Check that you recognize the address under After approval you will be sent to. If the address is unfamiliar, don't approve.
    • Select Approve, then sign in to LottieFiles if asked.
  5. Turn it on in a chat. Start a new chat. Select + → Connectors and make sure Creator MCP is on. Then ask for an animation.

For Claude Team and Enterprise:

  1. An Owner adds the connector in Organization settings → Connectors.
  2. Each member then goes to Customize → Connectors and selects Connect.


ChatGPT (web and desktop app)

There is one setting you must change during setup, so follow step 2 carefully.

  1. Open Plugins. In ChatGPT, open Plugins in the sidebar. Select Add, then Create custom MCP server.
  2. Enter the server details and switch to DCR.
    • Enter Creator MCP as the name and paste the server address https://creator.mcp.lottiefiles.com/mcp.
    • Leave Authentication as OAuth.
    • Open Advanced OAuth settings and change Registration method to Dynamic Client Registration (DCR).
  3. Create the plugin. Tick I understand and want to continue, then select Create as a plugin. On smaller screens, scroll down inside the form to find the button. Then select Connect Creator MCP.
  4. Approve access on LottieFiles. On the LottieFiles approval page:
    • Check that the application is ChatGPT.
    • Check that you recognize the address under After approval you will be sent to. If the address is unfamiliar, don't approve.
    • Select Approve, then sign in to LottieFiles if asked.
  5. Use it in a chat. Start a new chat, type @Creator, select Creator MCP from the list, and ask for an animation.

Required step: choose DCR. ChatGPT's default registration method (Client Identifier Metadata Document, or CIMD) currently fails sign-in with the error unknown client_id. You must select DCR before you create the plugin. You can't change it afterward.

Adding the plugin again: Plugin names must be unique. If you need to add Creator MCP again, first delete the old plugin in Settings → Plugins, or use a different name.


Developer tools

Use these steps for coding agents, code editors, and terminal apps. The server uses Streamable HTTP with OAuth sign-in.

Claude Code

  1. Run this command in your terminal:

    claude mcp add --transport http --scope user creator-mcp https://creator.mcp.lottiefiles.com/mcp

  2. Inside a Claude Code session, run /mcp and select creator-mcp.

  3. Complete the LottieFiles sign-in and approval in your browser.

Tip: --scope user makes Creator MCP available in all your projects. Leave it out to add it to the current folder only.

Codex, Cursor, VS Code, Devin Desktop (Windsurf), and other apps

  1. Open your app's MCP settings or MCP configuration file.
  2. Add a remote (HTTP) MCP server with the server address.
  3. Start the sign-in from the app and complete the LottieFiles sign-in and approval in your browser.

The exact settings for each app are in the developer guide: Connect your MCP client.

  • If you edit a configuration file, add the Creator MCP entry next to your existing servers. Don't replace the other servers.
  • If your app only supports local (stdio) MCP servers, use the bridge described under Other clients in the developer guide.


Check that it works

Send this message in a new chat:

List the tools available from Creator MCP, then read its animation overview.

You should see a list of tools that start with creator_, including at least creator_exec, creator_docs, and creator_document. Other tools appear depending on your app. If the tools don't appear, see Troubleshooting: connection and sign-in.
