WHAT IT DOES

What web3_revoke_key does on 0xarchive

AI agents call web3_revoke_key to permanently remove resources in 0xarchive, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why web3_revoke_key is rated Critical

Revoking an API key is an irreversible action that permanently destroys access credentials. Once revoked, the key cannot be restored, making this a destructive operation. Misuse by an AI agent could lock out legitimate users or services from the platform, with high blast radius if the wrong key is revoked.

The rule that runs web3_revoke_key safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0xarchive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For web3_revoke_key, this is the rule to start with:

web3_revoke_key Hidden

web3_revoke_key is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
