# list_devices A read tool on the API-Central MCP server. Agent View of the PolicyLayer registry record for `list_devices`. HTML page: https://policylayer.com/tools/secure-ssid-centralmcp/list-devices ## Facts - Tool: `list_devices` - Server: API-Central (`secure-ssid/centralmcp`) — https://policylayer.com/tools/secure-ssid-centralmcp.md - Homepage: https://github.com/secure-ssid/centralmcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - 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_devices", "arguments": {} } } ``` ## Why list_devices is rated Low The 'list_devices' tool retrieves or queries device data from the network management platform. No side effects are indicated or implied by the name or function in the broader server context (which includes write operations like 'add_devices_to_group' and 'add_visitor' as separate tools). This is a standard read operation with low blast radius if misused—worst case is information disclosure about managed devices. From the tool's own definition: "Tool name 'list_devices' indicates retrieval of device information without modification. Context shows this is part of HPE Aruba Central network monitoring and operations tools, where listing devices is a read-only discovery operation." ## Use case AI agents call list_devices to retrieve information from API-Central 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 API-Central: ```json { "version": "1", "default": "deny", "tools": { "list_devices": {} } } ``` ## Other tools on API-Central (589) - `aos8_execute_migration_rollback` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/aos8-execute-migration-rollback.md - `aos8_logout` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/aos8-logout.md - `apstra_delete_connectivity_template` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/apstra-delete-connectivity-template.md - `clear_alerts` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/clear-alerts.md - `clearpass_delete_endpoint` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/clearpass-delete-endpoint.md - `clearpass_delete_guest` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/clearpass-delete-guest.md - `delete_aaa_profile` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-aaa-profile.md - `delete_auth_profile` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-auth-profile.md - `delete_auth_server` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-auth-server.md - `delete_authz_policy` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-authz-policy.md - `delete_config_assignment` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-config-assignment.md - `delete_device_groups` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-device-groups.md - `delete_device_notes` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-device-notes.md - `delete_glp_role_assignment` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-glp-role-assignment.md - `delete_glp_scope_group` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-glp-scope-group.md - `delete_glp_scope_group_scopes` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-glp-scope-group-scopes.md - `delete_gw_policy` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-gw-policy.md - `delete_mac_registration` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-mac-registration.md - `delete_mpsk_registration` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-mpsk-registration.md - `delete_network_profile` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-network-profile.md - `delete_notification_rule` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-notification-rule.md - `delete_overlay_ssid` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-overlay-ssid.md - `delete_report` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-report.md - `delete_report_run` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-report-run.md - `delete_role` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-role.md - `delete_role_acl` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-role-acl.md - `delete_server_group` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-server-group.md - `delete_site_collections_bulk` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-site-collections-bulk.md - `delete_sites_bulk` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-sites-bulk.md - `delete_static_tag` — Destructive — https://policylayer.com/tools/secure-ssid-centralmcp/delete-static-tag.md - …and 559 more: https://policylayer.com/tools/secure-ssid-centralmcp.md ## For agents This record is a snapshot.
