Supported AI models
Membrane connects to Claude.ai and ChatGPT. Here's which plans support custom connectors, and what each one gives you.
As of today
Claude.ai
Every paid Claude plan supports unlimited custom connectors. The free tier supports a single connector at a time — fine for trying Membrane out.
| Plan | Custom connectors | Notes |
|---|---|---|
| Claude Free | 1 at a time | Works, but if you already have another connector installed you'll need to swap. |
| Claude Pro | Yes | Unlimited connectors. Best starter plan. |
| Claude Max | Yes | Unlimited connectors. Higher usage caps. |
| Claude Team | Yes | Unlimited. Connectors set up per user. |
| Claude Enterprise | Yes | Unlimited. May require workspace admin to allow custom connectors. |
ChatGPT
ChatGPT custom connectors require Developer Mode, which is only available on paid plans. The free tier doesn't currently support custom MCP connectors.
| Plan | Custom connectors | Notes |
|---|---|---|
| ChatGPT Free | No | No custom connector support. Connect Claude Free instead if you're starting out. |
| ChatGPT Plus | No | Plus doesn't include Developer Mode today. |
| ChatGPT Pro | Yes | Requires enabling Developer Mode in settings first. |
| ChatGPT Team | Yes | Requires Developer Mode. Workspace admin can set defaults. |
| ChatGPT Enterprise | Yes | Requires Developer Mode. Admin approval may be needed. |
| ChatGPT Edu | Yes | Requires Developer Mode. Good fit for research usage. |
Not sure which to pick?
If you're just trying Membrane out, Claude Free is the simplest path — one connector slot, no Developer Mode, working in under a minute. For a main workflow, Claude Pro or ChatGPT Pro both work well; pick whichever your team already uses.
What's not supported
Developer-focused MCP clients
Claude Code, Cursor, Windsurf, Cline, Continue.dev, and similar developer tools can connect to Membrane via MCP, but this support site is for advertisers — those flows aren't documented here.
Other AI assistants
Gemini, Copilot, Perplexity, and other assistants don't currently support MCP connectors. If that changes, we'll add setup steps for them.
