WHAT IT DOES

What re_yara does on Rekit

AI agents call re_yara as a supporting operation in Rekit workflows.

RISK

Why re_yara is rated Low

Without any rule in front of it, every call an agent makes to re_yara happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs re_yara safely

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

re_yara Rate-limited

re_yara gets a rate cap, and everything else on the server is denied unless you say otherwise.
