TESERAAccess keys
Tesera works without a key. A key gives an agent or a team higher limits and shows how much each one is used. You make one by signing a message with your wallet, so there is no account and no password.
Your keys
Using a key
Send it as a header
Add Authorization: Bearer tsk_... to requests to mcp.teseralab.com/elysium. Claude Code, Cursor, VS Code and most agent frameworks let you set headers on a remote MCP server. The docs show each one.
Chat apps
Claude and ChatGPT connectors do not send custom headers yet, so they use Tesera without a key. That is fine for one person chatting.
Shown once
Tesera keeps only a fingerprint of each key, so it cannot show it again. If you lose one, revoke it and make another.
Not a wallet key
An access key cannot sign or move anything. Tesera never asks for a private key or seed phrase, and signing here only proves which wallet owns the keys.
