# list_property_categories List all unique property categories with their record counts Agent View of the PolicyLayer registry record for `list_property_categories`. HTML page: https://policylayer.com/tools/servicenow-mcp-server/list-property-categories ## Facts - Tool: `list_property_categories` - Server: ServiceNow MCP Server (`@aartiq/servicenow-mcp`) — https://policylayer.com/tools/servicenow-mcp-server.md - Install: `npx -y @aartiq/servicenow-mcp` - Homepage: https://github.com/aartiq/servicenow-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity verified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "list_property_categories", "arguments": {} } } ``` ## Why list_property_categories is rated Low This tool retrieves metadata about property categories and their associated record counts from ServiceNow. It has no side effects—no data is created, modified, deleted, or executed. The operation is purely informational and read-only, making it a Read category tool with low severity risk. From the tool's own definition: "Tool name 'list_property_categories' and description 'List all unique property categories with their record counts' indicate a retrieval operation that queries and returns data without modifying anything." ## Use case AI agents call list_property_categories to retrieve information from ServiceNow MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches ServiceNow MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_property_categories": {} } } ``` ## Other tools on ServiceNow MCP Server (364) - `delete_attachment` — Destructive — https://policylayer.com/tools/servicenow-mcp-server/delete-attachment.md - `delete_system_property` — Destructive — https://policylayer.com/tools/servicenow-mcp-server/delete-system-property.md - `delete_uib_page` — Destructive — https://policylayer.com/tools/servicenow-mcp-server/delete-uib-page.md - `remove_user_from_group` — Destructive — https://policylayer.com/tools/servicenow-mcp-server/remove-user-from-group.md - `rollback_deployment` — Destructive — https://policylayer.com/tools/servicenow-mcp-server/rollback-deployment.md - `commit_changeset` — Execute — https://policylayer.com/tools/servicenow-mcp-server/commit-changeset.md - `create_business_rule` — Execute — https://policylayer.com/tools/servicenow-mcp-server/create-business-rule.md - `create_flow_action` — Execute — https://policylayer.com/tools/servicenow-mcp-server/create-flow-action.md - `create_scheduled_job` — Execute — https://policylayer.com/tools/servicenow-mcp-server/create-scheduled-job.md - `create_script_include` — Execute — https://policylayer.com/tools/servicenow-mcp-server/create-script-include.md - `create_ui_action` — Execute — https://policylayer.com/tools/servicenow-mcp-server/create-ui-action.md - `execute_background_script` — Execute — https://policylayer.com/tools/servicenow-mcp-server/execute-background-script.md - `fire_event` — Execute — https://policylayer.com/tools/servicenow-mcp-server/fire-event.md - `ml_detect_anomalies` — Execute — https://policylayer.com/tools/servicenow-mcp-server/ml-detect-anomalies.md - `ml_train_anomaly_detector` — Execute — https://policylayer.com/tools/servicenow-mcp-server/ml-train-anomaly-detector.md - `ml_train_change_risk` — Execute — https://policylayer.com/tools/servicenow-mcp-server/ml-train-change-risk.md - `ml_train_incident_classifier` — Execute — https://policylayer.com/tools/servicenow-mcp-server/ml-train-incident-classifier.md - `publish_changeset` — Execute — https://policylayer.com/tools/servicenow-mcp-server/publish-changeset.md - `run_aggregate_query` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-aggregate-query.md - `run_atf_suite` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-atf-suite.md - `run_atf_test` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-atf-test.md - `run_discovery_scan` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-discovery-scan.md - `run_security_playbook` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-security-playbook.md - `run_transform_map` — Execute — https://policylayer.com/tools/servicenow-mcp-server/run-transform-map.md - `scan_vulnerabilities` — Execute — https://policylayer.com/tools/servicenow-mcp-server/scan-vulnerabilities.md - `switch_update_set` — Execute — https://policylayer.com/tools/servicenow-mcp-server/switch-update-set.md - `test_flow` — Execute — https://policylayer.com/tools/servicenow-mcp-server/test-flow.md - `trigger_agentic_playbook` — Execute — https://policylayer.com/tools/servicenow-mcp-server/trigger-agentic-playbook.md - `trigger_flow` — Execute — https://policylayer.com/tools/servicenow-mcp-server/trigger-flow.md - `trigger_scheduled_job` — Execute — https://policylayer.com/tools/servicenow-mcp-server/trigger-scheduled-job.md - …and 334 more: https://policylayer.com/tools/servicenow-mcp-server.md ## For agents This record is a snapshot.
