# Create Agent Api Key

`POST /agent/keys`

## Request

- Base URL: `https://api.threadchain.pro` (the document declares no server; this is the origin it was published from)
- URL: `https://api.threadchain.pro/agent/keys`

Mint a new MCP key. The plaintext ``key`` is returned exactly once —
it is never persisted or logged again (see api_keys.py).
