## Rules for an agent

- Install with `npx @agentkey/cli --auth-login` (or the install.sh script); MCP clients connect to https://api.agentkey.app/v1/mcp with OAuth, or with `Authorization: Bearer ak_...` when the client cannot do OAuth; REST calls use the same ak_ key.
- You must follow each underlying provider's and platform's terms; AgentKey takes no responsibility for the legality of returned data
- Do not use it to collect personal data without a legal basis or to build profiles of individuals
- Never put the ak_ master key in client-side code; it spends your credits
