WHAT IT DOES

What signet-policy-set does on Nostr Bray

AI agents use signet-policy-set to create or update resources in Nostr Bray, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nostr Bray environment.

RISK

Why signet-policy-set is rated Medium

This tool creates or modifies policy configuration data (verification tiers, trust score requirements, enforcement mode) by publishing a signed Nostr event. It is reversible—a new policy can be published to override it. The impact is constrained to policy metadata rather than user data or financial transactions.

From the tool's definition Tool publishes a Nostr event (kind 30078) that sets access control policies. Key actions: 'Publish', 'Sets minimum verification tiers', 'enforcement mode'. These modify policy state that affects who can access or interact with a community.

RECOMMENDED RULE

The rule that runs signet-policy-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 signet-policy-set, this is the rule to start with:

signet-policy-set Rate-limited

signet-policy-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.
