How to connect AI assistants to Exchange Server SE
Postgate AI is an MCP server - it works with every MCP-capable system: from chat assistants like Claude, ChatGPT & co. to agentic automation platforms like Google Antigravity and Microsoft Copilot Studio that build autonomous Exchange workflows on top. Here are the step-by-step guides.
The basic pattern is always the same
Copy your MCP address
Your personal MCP address is on the portal dashboard under "Connect your AI assistant" - copied with one click.
Add the connector
Create a custom connector in your AI assistant and paste the MCP address. No token, no client ID required.
Sign in via OAuth
On first access the assistant redirects you to the Postgate AI sign-in. After that it works with your own Exchange permissions.
