WHAT IT DOES

What update_report does on ServiceNow MCP Server

AI agents use update_report 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.

RISK

Why update_report is rated Medium

This tool modifies report definitions in ServiceNow, which is reversible (reports can be updated again or reverted). It does not permanently delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely read data (Read).

From the tool's definition Tool description explicitly states it "Update[s] an existing saved report definition". The action modifies data (report definitions) in a reversible manner. The requirement 'WRITE_ENABLED=true' confirms this is a write operation gated by permission.

RECOMMENDED RULE

The rule that runs update_report 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 update_report, this is the rule to start with:

update_report Rate-limited

update_report 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.
