What capture_get_encodings does on Propresenter
AI agents call capture_get_encodings to retrieve information from Propresenter without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why capture_get_encodings is rated Low
This tool performs a read-only query to retrieve available encoding options. It has no side effects, does not execute code, does not modify data, and does not involve financial operations. The blast radius of misuse is minimal—an agent could only enumerate available encodings, which is informational metadata about the ProPresenter system.
From the tool's definition Tool name 'capture_get_encodings' and description 'Get available capture encodings for a specific type' indicate a query operation that retrieves configuration or capability information without modifying state.
Attacks that exploit this kind of access
The rule that runs capture_get_encodings safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Propresenter, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capture_get_encodings, this is the rule to start with:
capture_get_encodings 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 Propresenter, apply this rule, and every capture_get_encodings call is checked against it from then on.
