| Platform | Best for | Connect how | Auth |
|---|---|---|---|
| ChatGPT App | Consumers, OAuth, no local setup | Install Guides from ChatGPT apps → Sign in with Guides | OAuth at guides.co |
| ChatGPT Custom GPT | Builders who want OpenAPI control | Actions → import /api/gdf/v1/openapi.json | Bearer API key |
| Cursor | Developers editing docs/code + guides in IDE | Settings → MCP → local guides-gdf-mcp | Bearer API key in MCP env |
| Claude Desktop | Same as Cursor | claude_desktop_config.json | Bearer API key in MCP env |
Important: The public hosted MCP at https://mcp.guides.co/mcp uses OAuth (for ChatGPT). Cursor does not use that URL today - run the local MCP server with your API key. See Guides MCP setup.
