table_create · ServiceNow MCP Server MCP: Risk & Policy

WHAT IT DOES

What table_create does on ServiceNow MCP Server

AI agents use table_create 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 IT NEEDS A POLICY

Why table_create needs a policy

This tool creates new records in ServiceNow's database across any table. While reversible (records can be deleted), the ability to write to arbitrary tables in an ITSM system poses high risk: an AI agent could create malicious incidents, fake change requests, unauthorized assets, or corrupt CMDB data. The lack of table restriction and the breadth of ServiceNow's data model elevate this from medium to high severity.

From the tool's definition Tool name is 'table_create' with description 'Create a record in any table' — directly creates data across arbitrary ServiceNow tables without deletion or financial transfer.
