Return pandas describe() summary for the global dataframe.
AI agents call describe_df to retrieve information from Vibe Preprocessing and Analysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The describe() method in pandas generates summary statistics (mean, std, min, max, quartiles, etc.) for numeric columns. This is a pure query operation with no side effects. It does not create, modify, delete, or execute arbitrary code. The tool merely returns pre-computed statistics from an existing dataframe, making it a straightforward Read category operation with low severity and high confidence.
From the tool's definition Tool description states 'Return pandas describe() summary for the global dataframe' — a read-only operation that retrieves statistical summaries without modifying data.
Attacks that exploit this kind of access
Return pandas describe() summary for the global dataframe. It is categorised as a Read tool in the Vibe Preprocessing and Analysis MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vibe Preprocessing and Analysis MCP Server MCP server in PolicyLayer and add a rule for describe_df: 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 Vibe Preprocessing and Analysis MCP Server. Nothing to install.
describe_df 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 describe_df 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 describe_df. 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.
describe_df is provided by the Vibe Preprocessing and Analysis MCP Server MCP server (mudit14224/vibe-data-analysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
describe_df is one line of Vibe Preprocessing and Analysis MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
