Use external tools in offgen (MCP connectors)
Connect an external MCP server to offgen so the agent can use its tools in chat.
Connect a remote MCP server, such as your ticketing or CRM tool, and the offgen agent can call its tools: in Chat in the web app and in the AI Agent in PowerPoint. This is the opposite direction of connecting an AI assistant to offgen.
Where: Settings → Integrations → MCP connectors at app.offgen.ai · Who: all members for their own connectors. Owners and Admins for connectors shared with the organization.
Only connect servers you trust. The agent can read data and take actions through a connected server without asking first.
Add a connector
- Open MCP connectors and select Add connector.
- Enter a Name and the Server URL. The server must use HTTPS and Streamable HTTP.
- Under Authentication, choose OAuth, API key or None. For an API key, also set the Header, for example
Authorization: BearerorX-API-Key. - Owners and Admins choose who can use it under Available to: Only me or Everyone in my organization.
- Select Connect. offgen checks the connection when it saves.
- For OAuth, select Sign in and sign in to the external service.
When an Admin shares an OAuth connector, everyone sees it and signs in with their own account. A shared API key connector uses the key the Admin entered for everyone.
Use it in chat
Every connector you can see is on in every chat. In Chat in the web app, open the + menu and use Connectors to switch one off for that chat. The AI Agent in PowerPoint always uses all of them. Steps that call a connector show Used and the connector's name.
Manage a connector
Open a connector to see its status and its Tools. Turned-off tools are never shown to the agent. Only the connector's owner can switch tools, and for shared connectors that means an Owner or Admin.
| Status | What to do |
|---|---|
| Connected | Nothing. |
| Needs sign-in | Select Sign in. |
| Sign-in expires soon | Select Reconnect. |
| Unreachable | Check the URL and the server, then select Test connection. |
| Not verified yet | Select Test connection. |
Edit changes the settings, Sign out removes your sign-in, and Remove deletes the connector and its stored credentials. Removing a shared connector removes it for everyone.
