Creates a new, empty presentation with the given filename,
AI agents use create_or_clear_presentation to create or update resources in PPTX MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PPTX MCP Server environment.
This tool creates a new file artifact (a PPTX presentation). While file creation is a write operation, it is reversible (the file can be deleted), so it does not qualify as Destructive. The 'or_clear' aspect suggests it may also overwrite existing presentations, which could be destructive if applied to an existing file, but the primary description emphasizes creation.
From the tool's definition Tool description states it 'Creates a new, empty presentation with the given filename', which is a write operation that creates a new file.

PolicyLayer is an MCP gateway — it sits between your AI agents and PPTX MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_or_clear_presentation:
{
"version": "1",
"default": "deny",
"tools": {
"create_or_clear_presentation": {
"limits": [
{
"counter": "create_or_clear_presentation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_or_clear_presentation 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.

Creates a new, empty presentation with the given filename,. It is categorised as a Write tool in the PPTX MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PPTX MCP Server MCP server in PolicyLayer and add a rule for create_or_clear_presentation: 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 PPTX MCP Server. Nothing to install.
create_or_clear_presentation 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 create_or_clear_presentation 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 create_or_clear_presentation. 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.
create_or_clear_presentation is provided by the PPTX MCP Server MCP server (samos123/pptx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
