Add a new slide to a presentation at an optional position with a layout
AI agents use google_slides_add_slide to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
This tool creates new slides in a presentation, which is a reversible modification of data (slides can be deleted). It does not execute arbitrary code, delete data irreversibly, move money, or retrieve information without side effects. The medium severity reflects that an AI agent could spam a presentation with unwanted slides, but the impact is limited to the target presentation and easily undone.
From the tool's definition Tool name 'google_slides_add_slide' and description 'Add a new slide to a presentation' indicate creation of new content in Google Slides.

PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for google_slides_add_slide:
{
"version": "1",
"default": "deny",
"tools": {
"google_slides_add_slide": {
"limits": [
{
"counter": "google_slides_add_slide_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}google_slides_add_slide stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add a new slide to a presentation at an optional position with a layout. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for google_slides_add_slide: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Sage MCP. Nothing to install.
google_slides_add_slide is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the google_slides_add_slide rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for google_slides_add_slide. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
google_slides_add_slide is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
