What cmdb_reconcile does on NowAIKit — ServiceNow AI Toolkit
AI agents call cmdb_reconcile to permanently remove resources in NowAIKit — ServiceNow AI Toolkit, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why cmdb_reconcile is rated Critical
Although the tool offers a dry_run mode for safety, its core capability to retire or remove CIs constitutes destructive operations that cannot be easily undone and could have severe consequences for infrastructure management, compliance tracking, and dependent systems. The ability to merge CIs also irreversibly consolidates records.
From the tool's definition Tool description explicitly states it can "merge, retire, or remove" CIs (Configuration Items), which are irreversible operations that modify or delete infrastructure records in the CMDB.
Attacks that exploit this kind of access
The rule that runs cmdb_reconcile safely
PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cmdb_reconcile, this is the rule to start with:
cmdb_reconcile is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every cmdb_reconcile call is checked against it from then on.

Register the NowAIKit — ServiceNow AI Toolkit MCP server in PolicyLayer and add a rule for cmdb_reconcile: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NowAIKit — ServiceNow AI Toolkit. Nothing to install.
cmdb_reconcile is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the cmdb_reconcile rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
