WHAT IT DOES

What pillar_key_lock does on Aibtc

AI agents invoke pillar_key_lock to trigger actions in Aibtc. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why pillar_key_lock is rated High

This tool performs an irreversible in-session operation that clears sensitive cryptographic key material from memory. While not deleting persistent data, locking/clearing a signing key is an operational action with significant consequences — it could prevent transaction signing, disrupt ongoing operations, or require re-authentication.

From the tool's definition Lock the signing key, clearing sensitive data from memory.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

pillar_key_lock Rate-limited

pillar_key_lock stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
