You need one thing: your personal link. It looks like
https://skills.percerno.ai/u/XXXXXXXX/mcp and you get it from whoever runs the service.
It is your key. Do not forward it; if it leaks, ask for a new one.
Open your personal link in a browser without the /mcp at the end:
https://skills.percerno.ai/u/XXXXXXXX/
That is your page. Type what you need in the chat box, attach a file if there is one, and you get a download link back. Nothing to install, nothing to configure. If the chat box is not there, the service has no hosted model yet; use option 2.
Pick yours. In every case the URL to paste is your personal link, with /mcp.

Say what you want and what file you want back. Good examples:
When the result is a file you get a download link (valid for one hour; ask again if it expired). When the result is text, a plan, a draft or advice, the answer simply appears in the chat, like any other reply.
| What you see | What it means | What to do |
|---|---|---|
| "unauthorized" when adding the connector | The link is mistyped or revoked | Copy it again from the message you got, or ask for a new one |
| The assistant answers with text but no file | It did not understand you wanted a file | Add "as a PowerPoint/Word/Excel file" to your request |
| "link expired" when downloading | Links live for one hour | Ask the assistant for the file again |
| The assistant says it cannot see the tools | The connector is off in this chat | Open the chat's tools menu and switch Percerno Skills on |
