WHAT IT DOES

What list_discovery_credentials does on ServiceNow-MCP

AI agents call list_discovery_credentials 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 list_discovery_credentials is rated Low

This is a read-only query tool that lists credential metadata without exposing sensitive secret values. The blast radius of misuse is minimal: an attacker would learn credential names and configurations but not the secrets themselves, limiting downstream exploitation potential. Low severity appropriate for informational retrieval.

From the tool's definition Tool performs 'List Discovery credential METADATA' — explicitly retrieves metadata only (name, type, order, MID scope) with secret fields explicitly excluded from return. No modification, execution, deletion, or financial operations occur.
