# About this connection

`whoami`

- Read-only

Reports who this connection acts for and what it may do: the person’s first name, whether they are a student or a member of staff, the olympiads the connection covers and the role held on each, whether changes were approved, and when the access expires. Call it once at the start of a session — every other tool needs the olympiad slug this returns, and a tool missing from the list is one this person’s roles do not reach. It makes no change and costs nothing.

- **For**: Students, teachers and partners
- **Needs**: Read access (`mcp:read`)
- **What it changes**: **Read-only.** It only reads. Nothing changes.

## Inputs

None.

## Answers instead of a result

What the tool says when it cannot do what was asked, and what to do about it.
