RECOMMENDED RULE

The rule that runs zap-wallet-set safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nostr Bray, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For zap-wallet-set, this is the rule to start with:

zap-wallet-set Rate-limited

zap-wallet-set stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
