WHAT IT DOES

What identity_set_approval does on Aibtc

AI agents use identity_set_approval 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 identity_set_approval is rated Medium

This tool modifies access control settings by granting or revoking operator permissions on a blockchain identity registry. While potentially reversible (approval can be revoked), it fundamentally changes who has authority over an agent identity, which could allow an unauthorized party to control the identity if misused. This is a Write operation with high severity due to the access control implications.

RECOMMENDED RULE

The rule that runs identity_set_approval 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 identity_set_approval, this is the rule to start with:

identity_set_approval Rate-limited

identity_set_approval 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.
