On Claude on the web, or in Claude Desktop:

1. Open Customize, then Connectors.
2. Choose + Add, then Add custom connector.
3. Name it Glass Page, paste the MCP server address, and choose Continue.
4. Review the authentication settings Claude detected, then choose Continue.
5. Under Authentication, choose Sign in now.
6. Under OAuth client, choose Register automatically, then Add, and sign in to Glass Page.

On a Team or Enterprise plan, an owner of your Claude organization adds it first, under Organization settings, then Connectors, and each person then chooses Connect. On Free, it can be your one custom connector. Once it's connected, it shows in Connected apps, where you can disconnect it.

Add the server, for every project:

claude mcp add --transport http --scope user glass-page https://mcp.glasspage.ai/mcp

Then run /mcp in Claude Code, choose glass-page, then Authenticate, and sign in to Glass Page in your browser. Once it's connected, it shows in Connected apps, where you can disconnect it.

On ChatGPT on the web:

1. Open Plugins, choose +, then Add custom MCP server.
2. Name it Glass Page, and paste the MCP server address as its Server URL.
3. For authentication, choose OAuth, with no client ID or secret, so ChatGPT registers itself.
4. Review the risk warning, and check I understand and want to continue.
5. Choose Create as a plugin, install it, and sign in to Glass Page.

It can publish on ChatGPT Business, Enterprise, and Edu. On Business, only workspace admins and owners can add it; on Enterprise and Edu, admins can let others. On other plans, check OpenAI's guides, Connecting custom MCP servers in ChatGPT and Add custom MCP server. Once it's connected, it shows in Connected apps, where you can disconnect it.

Add the server to ~/.cursor/mcp.json, for every project, or to .cursor/mcp.json in one:

{
  "mcpServers": {
    "glass-page": {
      "url": "https://mcp.glasspage.ai/mcp"
    }
  }
}

Cursor then asks you to sign in to Glass Page in your browser. Once it's connected, it shows in Connected apps, where you can disconnect it.

Add the server for your user, from a terminal. On macOS and Linux:

code --add-mcp '{"name":"glass-page","type":"http","url":"https://mcp.glasspage.ai/mcp"}'

On Windows, in Command Prompt:

code --add-mcp "{\"name\":\"glass-page\",\"type\":\"http\",\"url\":\"https://mcp.glasspage.ai/mcp\"}"

Or in PowerShell:

code --add-mcp '{\"name\":\"glass-page\",\"type\":\"http\",\"url\":\"https://mcp.glasspage.ai/mcp\"}'

Or run MCP: Add Server from the Command Palette, choose HTTP, paste the MCP server address, and name it glass-page.

The first time VS Code connects, it opens your browser to sign in to Glass Page. Allow it when VS Code asks. Once it's connected, it shows in Connected apps, where you can disconnect it.

Add the server, for every project. It then opens your browser, to sign in to Glass Page:

codex mcp add glass-page --url https://mcp.glasspage.ai/mcp

If it didn't sign you in, or to sign in again:

codex mcp login glass-page

The Codex command line, its IDE extension, and the ChatGPT desktop app share this setup, in ~/.codex/config.toml. On a machine with no browser, such as over SSH, stop the add command's sign-in with Ctrl-C once it has added the server, then run codex mcp login glass-page --no-browser, open the address it prints on another device, and paste the address the sign-in ends on back into the terminal. See OpenAI's guide, Model Context Protocol. Once it's connected, it shows in Connected apps, where you can disconnect it.

In LM Studio, open the Program tab in the right-hand sidebar, choose Install, then Edit mcp.json, and add the server:

{
  "mcpServers": {
    "glass-page": {
      "url": "https://mcp.glasspage.ai/mcp"
    }
  }
}

Save it, and LM Studio opens your browser to sign in to Glass Page. Once it's connected, it shows in Connected apps, where you can disconnect it.

Update LM Studio first: older versions can't sign in to an MCP server. See LM Studio's guides, Use MCP servers and MCP integrations.

For an agent that can't sign you in, create an API Key. The agent sends it in this header on every request:

Authorization: Bearer <your API Key>

Many clients take a settings file like this one. Some leave out type:

{
  "mcpServers": {
    "glass-page-key": {
      "type": "http",
      "url": "https://mcp.glasspage.ai/mcp",
      "headers": {
        "Authorization": "Bearer <your API Key>"
      }
    }
  }
}

Or add it to Claude Code with a key, under its own name, glass-page-key, apart from the sign-in setup:

claude mcp add --transport http --scope user glass-page-key https://mcp.glasspage.ai/mcp --header "Authorization: Bearer <your API Key>"

Or, for Codex, which reads the key from an environment variable, under that same name:

codex mcp add glass-page-key --url https://mcp.glasspage.ai/mcp --bearer-token-env-var GLASS_PAGE_API_KEY

On macOS and Linux, put your key in a file of its own, such as ~/.config/glass-page.env, never in a project, and never commit it:

export GLASS_PAGE_API_KEY="<your API Key>"

Then load it in your shell's profile, such as ~/.zshrc or ~/.bashrc:

[ -f ~/.config/glass-page.env ] && . ~/.config/glass-page.env

On Windows, set it for your account in PowerShell:

setx GLASS_PAGE_API_KEY "<your API Key>"

GLASS_PAGE_API_KEY reaches only Codex started from a terminal opened after you set it. The ChatGPT desktop app and the IDE extension may not see it, so sign them in with OAuth instead, as Codex's steps show.
