Free plans allow one custom connector; Pro, Max, Team and Enterprise more. On Team and Enterprise an Owner adds it under Organization settings, Connectors, then members choose Connect.

Google Gemini

In the Gemini web app: Settings, Connected Apps, Add a custom app, enter https://mcp.442ball.com/mcp and follow the steps; then type @ in a chat to use it. Google currently limits this to personal accounts, users 18 or over in the US, in English. Gemini Enterprise administrators add it as a Custom MCP Server data store with No authentication.

Microsoft Copilot Studio

In an agent's Tools page: Add a tool, New tool, Model Context Protocol; enter the URL https://mcp.442ball.com/mcp, authentication None, Create, then Add to agent. We have not found official steps for the consumer Copilot app.

Developer tools

Cursor: add to ~/.cursor/mcp.json (or a project's .cursor/mcp.json):

{ "mcpServers": { "442ball": { "url": "https://mcp.442ball.com/mcp" } } }

VS Code (GitHub Copilot agent mode): Command Palette, MCP: Add Server, HTTP, enter the URL; or in .vscode/mcp.json:

{ "servers": { "442ball": { "type": "http", "url": "https://mcp.442ball.com/mcp" } } }

On Copilot Business and Enterprise, an organisation admin must turn on the "MCP servers in Copilot" policy. For Claude Desktop, use the connector steps above: its configuration file documents local servers only.
