WHAT IT DOES

What search_knowledge does on ServiceNow-MCP

AI agents call search_knowledge to retrieve information from ServiceNow-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_knowledge is rated Low

This tool performs a query operation against a knowledge base, returning matching articles based on search criteria. It does not create, modify, delete, or execute any actions—it only retrieves and presents information. This is a classic Read operation with minimal risk, even in a ServiceNow environment where knowledge bases may contain operational procedures or configurations.

From the tool's definition Tool name 'search_knowledge' and description 'Search knowledge base articles by keyword' indicate a retrieval operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs search_knowledge safely

search_knowledge Allowed

search_knowledge is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "search_knowledge": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ServiceNow-MCP, apply this rule, and every search_knowledge call is checked against it from then on.
