WHAT IT DOES

What snow_search_cmdb does on Serac

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

RISK

Why snow_search_cmdb is rated Low

This tool retrieves data from ServiceNow's Configuration Management Database (CMDB) using search filters. It has no side effects—it only queries and returns information. This is a classic Read operation. The severity is low because unauthorized access to CMDB data, while potentially revealing infrastructure details, does not directly enable immediate damage without subsequent actions through other tools.

From the tool's definition Tool name 'snow_search_cmdb' and description 'Search the CMDB for Configuration Items with various filters' indicates querying/searching functionality with no modification or execution of external operations.
