WHAT IT DOES

What badge-create does on Nostr Bray

AI agents use badge-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 badge-create is rated Medium

This tool creates new badge definitions (NIP-58 kind 30009 events), which modifies state by adding new badge metadata to the Nostr network. This is a reversible write operation—the badge definition can be updated or replaced (hence "replaceable"). It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition Tool description states "Define a new badge" and "Creates a replaceable badge definition with name, description, and optional image." The word "Creates" and "Define" are write operations that establish new data structures in the Nostr protocol.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

badge-create Rate-limited

badge-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.
