All MCP clients
Connect apps to ChatGPT with Arc0 MCP
Sign in to Arc0 and connect an available app in My apps. Early-access apps require enablement for your organization. Authorize ChatGPT separately so it can use the tools and accounts allowed for your identity.

- Open Plugins in ChatGPT, select the plus button, then Add custom MCP server.
- Name it Arc0, enter the server URL below, and choose OAuth. Use dynamic client registration if asked; no Arc0 API key is needed.
