What create_story does on ServiceNow MCP Server
AI agents use create_story to create or update resources in ServiceNow MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceNow MCP Server environment.
Why create_story is rated Medium
This tool creates new records (agile stories) in ServiceNow, which is a reversible data modification operation. While creation itself is a Write action, the medium severity reflects that stories are project management artifacts that could affect team workflows and planning if created maliciously or erroneously, but the impact is limited since story records can be deleted or archived.
From the tool's definition create_new agile story/user story (requires WRITE_ENABLED=true)' - explicitly states 'create' and requires write permission flag
Attacks that exploit this kind of access
The rule that runs create_story safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_story, this is the rule to start with:
create_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.
The button opens the PolicyLayer dashboard: create your workspace, connect ServiceNow MCP Server, apply this rule, and every create_story call is checked against it from then on.
