Why lspace_undo_knowledge_base_changes needs a policy

Undoing or reverting knowledge base changes (file uploads, KB generations) constitutes a destructive action because it removes or rolls back data that was previously stored. While 'undo' implies reversibility conceptually, reverting committed knowledge base entries destroys the current state irreversibly unless a separate backup exists.

From the tool's definition 'UNDO: Revert knowledge base changes' — reverts/undoes file uploads and KB generations, which is an irreversible rollback of previously committed knowledge base state

POLICY

How to control lspace_undo_knowledge_base_changes

PolicyLayer is an MCP gateway — it sits between your AI agents and Lspace MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for lspace_undo_knowledge_base_changes:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "lspace_undo_knowledge_base_changes"
  ]
}

lspace_undo_knowledge_base_changes disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Lspace MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
