Two details, one sign-in. You do this once – after that Perplexity knows your sessions in every new conversation.
Click the gear at the top right, then Account settings → Connectors. There, at the top right, click + Custom connector and choose Remote in the dialog. If the button is missing, your account is still on Free – custom connections start with Pro.
It is easiest with two windows side by side: this guide on the left, your AI on the right.
Two fields in the dialog matter: Name and MCP Server URL. Do not search the list of ready-made connections – Sessionario is not in it; it is entered by hand.
Name:
Sessionario
Server address (URL):
https://mcp.sessionario.com
Transport: Streamable HTTP. Authentication: choose OAuth 2.0 and leave client ID and secret empty. Our server registers the access itself; authorisation URL, token URL and scopes it publishes on its own too. Then tick the box at the bottom and click Add.
Should Perplexity insist on a client ID, this is where it stops – please drop us a line then. It is the one point we are still in the dark about.
Copy the address from here – a typo is the most common reason it does not work. And no trailing slash.
Now our sign-in window appears. The address bar says mcp.sessionario.com – that is how you know your password stays with us and does not reach the AI. Sign in with the Sessionario account your sessions live in.
Ask your AI something it can only know once the connection is live:
Two clicks help us more than any guess – on this page especially, because we have not verified it ourselves yet.
