What swap_voice does on Freshdesk
AI agents invoke swap_voice to trigger actions in Freshdesk. 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.
Why swap_voice is rated High
This tool modifies audio/video files by replacing voice content — it triggers a media processing operation with external effects. It doesn't simply read data, nor does it irreversibly delete data, but it does execute a transformation on media files. The misplacement on a Freshdesk/support server and lack of clear reversibility raises concern; misuse could involve voice impersonation or media manipulation.
From the tool's definition Replace the voice in an audio or video file with a different voice, preserving speech content.
Attacks that exploit this kind of access
The rule that runs swap_voice safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Freshdesk, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For swap_voice, this is the rule to start with:
swap_voice 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Freshdesk, apply this rule, and every swap_voice call is checked against it from then on.
