# protect_trigger_chime A execute tool on the UniFi Access MCP MCP server. Agent View of the PolicyLayer registry record for `protect_trigger_chime`. HTML page: https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-trigger-chime ## Facts - Tool: `protect_trigger_chime` - Server: UniFi Access MCP (`pypi:unifi-protect-mcp`) — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp.md - Install: `npx -y pypi:unifi-protect-mcp` - Homepage: https://github.com/sirkirby/unifi-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "protect_trigger_chime", "arguments": {} } } ``` ## Why protect_trigger_chime is rated High Triggering a chime is an Execute action—it causes an external device to perform an operation (produce sound) whose effects depend on context and cannot be trivially undone without causing some disruption. It's not Read (no data retrieval), Write (no data modification), Destructive (reversible), or Financial. From the tool's own definition: "Tool name 'protect_trigger_chime' suggests triggering an audio/chime output on physical security hardware. The empty description prevents full confirmation, but the name indicates activating a device action." ## Use case AI agents invoke protect_trigger_chime to trigger actions in UniFi Access MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches UniFi Access MCP: ```json { "version": "1", "default": "deny", "tools": { "protect_trigger_chime": { "limits": [ { "counter": "protect_trigger_chime_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on UniFi Access MCP (271) - `access_delete_visitor` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/access-delete-visitor.md - `access_revoke_credential` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/access-revoke-credential.md - `protect_alarm_delete_rule` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-alarm-delete-rule.md - `protect_delete_known_face` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-delete-known-face.md - `protect_delete_known_license_plate` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-delete-known-license-plate.md - `protect_delete_liveview` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-delete-liveview.md - `protect_delete_recording` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-delete-recording.md - `unifi_delete_acl_rule` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-acl-rule.md - `unifi_delete_ap_group` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-ap-group.md - `unifi_delete_backup` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-backup.md - `unifi_delete_client_group` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-client-group.md - `unifi_delete_content_filter` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-content-filter.md - `unifi_delete_dns_record` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-dns-record.md - `unifi_delete_dynamic_dns` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-dynamic-dns.md - `unifi_delete_firewall_group` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-firewall-group.md - `unifi_delete_firewall_policy` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-firewall-policy.md - `unifi_delete_oon_policy` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-oon-policy.md - `unifi_delete_port_forward` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-port-forward.md - `unifi_delete_port_profile` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-port-profile.md - `unifi_delete_wlan` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-delete-wlan.md - `unifi_forget_client` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-forget-client.md - `unifi_revoke_voucher` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-revoke-voucher.md - `unifi_unauthorize_guest` — Destructive — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-unauthorize-guest.md - `access_lock_door` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/access-lock-door.md - `access_reboot_device` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/access-reboot-device.md - `access_unlock_door` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/access-unlock-door.md - `protect_ptz_move` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-ptz-move.md - `protect_ptz_preset` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-ptz-preset.md - `protect_reboot_camera` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-reboot-camera.md - `unifi_batch` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-batch.md - …and 241 more: https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp.md ## For agents This record is a snapshot.
