The hosted gateway runs Ultra in the cloud. Instead of running ultra start on your machine, you point your agent at a URL. Ultra still applies your governance rules and guardrails and records every tool call in Ultra Hub.

​
When to use it

Use the hosted gateway for apps that run in the browser or the cloud, such as Claude.ai, ChatGPT, Microsoft 365 Copilot, and Microsoft Foundry.

​
Connect your agent

Every agent uses the same endpoint:
The first time your agent connects, it opens your browser to sign in to Ultra and approve the connection. Your workspace comes from your sign-in, so there’s nothing else to configure.
  1. In Claude, open Settings > Connectors and click Add custom connector.
  2. Paste the endpoint URL, click Add, then Connect.
If Ultra’s tools don’t appear, reconnect the connector or restart Claude.
In ChatGPT on the web, add a custom MCP server and paste the endpoint URL. Where the option appears depends on your plan; see OpenAI’s guide to adding a custom MCP server.
Add Ultra to your VS Code mcp.json (see Configure Agents for its location), then reload the window:
Add Ultra to ~/.cursor/mcp.json, then restart Cursor:
In your Foundry agent, add a remote MCP connector with the endpoint URL. If Ultra’s tools don’t appear after you sign in, reconnect it.
Office apps connect through an agent you build in Copilot Studio. See Microsoft 365 Copilot.
Many apps let you add a custom MCP server or connector. Wherever you see that option, paste the endpoint URL and sign in to Ultra when prompted.
