Connect AI assistants to Exchange Server by Postgate AI
Postgate AI is an MCP server - it works with every AI assistant that supports custom MCP connectors. Here you find step-by-step guides for the four major assistants.
The basic pattern is always the same
1. Copy your MCP address
Your personal MCP address is on the portal dashboard under "Connect your AI assistant" - copied with one click.
2. Add the connector
Create a custom connector in your AI assistant and paste the MCP address. No token, no client ID required.
3. 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.
