WHAT IT DOES

What get_decision does on Trace

AI agents call get_decision to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_decision is rated Low

This tool retrieves decision records by ID from what appears to be a code intelligence system's decision log. Fetching data is a read-only operation with no capability to modify, delete, or execute code. The blast radius of misuse is minimal—an attacker could only read decisions that may already be accessible through other means. No data is altered, deleted, or executed.

From the tool's definition Tool name 'get_decision' and description 'Fetch a single decision' indicate data retrieval with no modifications or side effects.

RECOMMENDED RULE

The rule that runs get_decision safely

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

get_decision Allowed

get_decision is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
