WHAT IT DOES

What nip-publish does on Nostr Bray

AI agents use nip-publish 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 nip-publish is rated Medium

Publishing a community NIP creates a new data record on Nostr (a community protocol specification). This is a Write operation because it adds/creates content that can potentially be modified or superseded later. It is not Destructive (no deletion/irreversible action), not Execute (no code execution or external command triggering), not Financial (no monetary transaction).

From the tool's definition Tool name 'nip-publish' and description 'Publish a community NIP (kind 30817)' — the verb 'publish' creates and writes a new protocol specification to Nostr, which is a reversible write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs nip-publish 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 nip-publish, this is the rule to start with:

nip-publish Rate-limited

nip-publish 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.
