A site's owner can give an AI agent a key that lets it read and change that site, and no other, over MCP. Keys are made under Agents, in Settings, below People and agents.

1. Name the agent, such as "Claude on my laptop", and press Give an agent access.
2. Copy the command it shows into Claude Code, or the JSON into any other agent. The key is shown once.

Each key then shows when it was last used. Revoke takes access away at once.

What can the agent do with it?

Read every page, change one block or a whole page, add pages and pictures, and undo its changes. Every change it makes goes into History like yours. A key never makes the agent an owner.
