Drop specified columns from the global DataFrame.
AI agents call drop_columns to permanently remove resources in Vibe Preprocessing and Analysis MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Dropping columns from a DataFrame is an irreversible destructive operation that removes data permanently from the in-memory structure. If the original CSV is not reloaded, the data is unrecoverable. The word 'drop' explicitly indicates removal. Severity is high because an AI agent could accidentally remove critical columns from the working dataset, corrupting ongoing analysis.

Attacks that exploit this kind of access
Drop specified columns from the global DataFrame. It is categorised as a Destructive tool in the Vibe Preprocessing and Analysis MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Vibe Preprocessing and Analysis MCP Server MCP server in PolicyLayer and add a rule for drop_columns: 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.
drop_columns is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the drop_columns 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 drop_columns. 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.
drop_columns 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.
