WHAT IT DOES

What update_story does on ServiceNow-MCP

AI agents use update_story to create or update resources in ServiceNow-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceNow-MCP environment.

RISK

Why update_story is rated Medium

This tool creates or modifies data reversibly within ServiceNow's agile management system. An agile story update can be reverted or corrected, making it a Write rather than Destructive action. Severity is medium because misconfigured updates could impact project planning and team coordination, but changes are not irreversible and their scope is limited to a single story record.

From the tool's definition Tool name 'update_story' and description 'Update an agile story' indicate modification of existing data. The requirement 'WRITE_ENABLED=true' confirms this is a write operation that alters stored records.

RECOMMENDED RULE

The rule that runs update_story safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_story, this is the rule to start with:

update_story Rate-limited

update_story stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
