WHAT IT DOES

What nostr_set_profile does on Aibtc

AI agents use nostr_set_profile to create or update resources in Aibtc, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aibtc environment.

RISK

Why nostr_set_profile is rated Medium

The tool performs a reversible write operation that modifies profile data. It is not Read (no query/retrieval), not Destructive (changes are reversible), not Execute (no code/shell execution), and not Financial (no monetary transactions). The medium severity reflects that unauthorized profile modifications could impact reputation or access control, but are not irreversible.

From the tool's definition Tool name contains 'set' and description states 'Update the agent', indicating modification of existing data.

RECOMMENDED RULE

The rule that runs nostr_set_profile safely

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

nostr_set_profile Rate-limited

nostr_set_profile 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.
