AI agents call themes_get_slide to retrieve information from Propresenter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries slide data from a theme in ProPresenter 7. It performs a read-only operation that does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an agent could only retrieve theme slide data that already exists. This is a straightforward Read category tool.
From the tool's definition Tool name 'themes_get_slide' and description 'Get a specific slide from a theme' indicate a retrieval operation with no modification or side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Propresenter, and nothing reaches the server without passing your rules. This is the rule we recommend for themes_get_slide:
{
"version": "1",
"default": "deny",
"tools": {
"themes_get_slide": {}
}
}themes_get_slide is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
