AI agents use add_ppt to create or update resources in ChatPPT-MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ChatPPT-MCP environment.
This tool creates or registers new documents in the RAG index—a reversible write operation. It does not execute code, delete data, or move funds. The impact is limited to indexing metadata and document references; the original documents remain intact. Severity is low because misuse would only result in unnecessary index entries, which can be reversed via the sibling tool 'delete_ppt'.
From the tool's definition Tool name 'add_ppt' and description '将指定的PPT文档添加到RAG索引中' (add specified PPT document to RAG index) indicates document addition/registration to a system.
Documented attack patterns abuse exactly the kind of access add_ppt gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ChatPPT-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add_ppt:
{
"version": "1",
"default": "deny",
"tools": {
"add_ppt": {
"limits": [
{
"counter": "add_ppt_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_ppt 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.

将指定的PPT文档添加到RAG索引中. It is categorised as a Write tool in the ChatPPT-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ChatPPT- MCP server in PolicyLayer and add a rule for add_ppt: 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 ChatPPT-MCP. Nothing to install.
add_ppt 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 add_ppt 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 add_ppt. 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.
add_ppt is provided by the ChatPPT- MCP server (pingcy/app_chatppt). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ChatPPT-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
