THE RISK

Why lspace_search_knowledge_base needs a policy

This tool retrieves information from a knowledge base without creating, modifying, or deleting any data. Syncing before search is a precautionary measure to ensure data consistency but remains a read operation. It presents minimal risk as misuse would only expose existing knowledge base content, not cause irreversible changes or financial impact.

From the tool's definition Tool name contains 'search' and description explicitly states 'Query the knowledge base using natural language.' The verb 'Query' and action 'search' indicate data retrieval with no side effects.

POLICY

How to control lspace_search_knowledge_base

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_search_knowledge_base:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "lspace_search_knowledge_base": {}
  }
}

lspace_search_knowledge_base is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
