Test new features with MCP

Connect ChatGPT directly to Wikilayer's MCP server to try new tools before they reach the official plugin.

Add a custom MCP server

Open Plugins, press Add, and choose Add custom MCP server.

The Add menu on the Plugins page: Create plugin / Upload plugin archive / Add custom MCP server

Fill in the server

Give it a name and paste this hosted Wikilayer MCP URL under Server URL:

https://wikilayer.org/mcp

Leave Authentication on OAuth, tick I understand and want to continue, then press Create as a plugin.

Add custom MCP server dialog with the name, the Wikilayer MCP URL and OAuth authentication

OpenAI's guide has the current steps if the screens change.

Authorize access

Wikilayer opens in your browser. Sign in and approve access. After that you are back in ChatGPT, and the plugin is in your Personal plugins: install it there, then pick it in a chat by typing @.
