# plungeai_whoami

> Show the authenticated identity: user id, tier, key label, rate-limit window.


Show the authenticated identity: user id, tier, key label and rate-limit window.

**Returns.** `# Who am I` with User, Auth (type and tier), Key (label and key id), Rate window (`<n>/min used · <n>/day used`, left out when the counter cannot be read) and Server. JSON: `{"user", "auth_type", "tier", "key_label", "key_id", "rate_window": {"minute_used", "day_used"} or null, "server"}`. Details: [Authentication & keys](https://mcp.plungeai.com/docs#2-authentication--keys).

```bash
# verify
# expect: Who am I
curl -s https://mcp.plungeai.com/v1 \
  -H "Authorization: Bearer $PLUNGE_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"plungeai_whoami","arguments":{"user_request":"who am I?"}}}'
```

<Note>
Two parameters recur across the tools: `user_request` (on every tool: a string of up to 4,000 characters, optional; clients should always send it) and `format` (`markdown` by default, or `json`). Both are described once in [Recurring parameters](/mcp-reference/overview#recurring-parameters) on the MCP overview.
