Parameters from the server's own tool schema.
Why environments_diff is rated Low
This tool retrieves or queries environment diff data through the Appaloft application catalog with no indication of side effects. It is a read-only operation that returns difference information between environments. The low severity reflects minimal blast radius—even if misused by an agent, it only exposes comparative configuration data without enabling modifications, deletions, or external operations.
From the tool's definition Tool description explicitly states 'Read environments.diff' and the name 'environments_diff' indicates a diff/comparison operation. The description uses the verb 'Read' to characterize the action.
Attacks that exploit this kind of access
The rule that runs environments_diff safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Appaloft, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For environments_diff, this is the rule to start with:
environments_diff is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Appaloft, apply this rule, and every environments_diff call is checked against it from then on.
