AI agents call ppt_get_chart_data to retrieve information from Ppt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing chart data without modifying, creating, deleting, or executing any operations. It is a straightforward data retrieval function, making it a Read category tool with low severity since reading chart data poses minimal risk if misused by an AI agent.
From the tool's definition Tool description explicitly states 'Read chart data from the underlying Excel workbook.' The verb 'Read' and the read-only nature of retrieving existing chart data confirms this is a retrieval operation with no side effects.

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

Read chart data from the underlying Excel workbook. It is categorised as a Read tool in the Ppt MCP Server, which means it retrieves data without modifying state.
Register the Ppt MCP server in PolicyLayer and add a rule for ppt_get_chart_data: 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 Ppt. Nothing to install.
ppt_get_chart_data is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ppt_get_chart_data 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 ppt_get_chart_data. 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.
ppt_get_chart_data is provided by the Ppt MCP server (ykuwai/ppt-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
