WHAT IT DOES

What vault-create does on Nostr Bray

AI agents use vault-create 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 vault-create is rated Medium

This tool creates and publishes a new Nostr event (kind 30078), which modifies the state of a decentralized system by introducing a new vault configuration with access control tiers. This is a Write operation—it creates data reversibly (the vault config can be updated or superseded by publishing new events). It is not Destructive because it does not delete or overwrite existing data irreversibly.

From the tool's definition Tool description states it "Create[s] a Dominion vault config" and "Signs and publishes the config as a kind 30078 event." The action is creating and publishing a new configuration object.

RECOMMENDED RULE

The rule that runs vault-create 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 vault-create, this is the rule to start with:

vault-create Rate-limited

vault-create 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.
