# unifi_list_devices A read tool on the UniFi Access MCP MCP server. Agent View of the PolicyLayer registry record for `unifi_list_devices`. HTML page: https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-list-devices ## Facts - Tool: `unifi_list_devices` - 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: 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": "unifi_list_devices", "arguments": {} } } ``` ## Why unifi_list_devices is rated Low The 'list' verb combined with '_devices' suffix strongly indicates a read-only query operation that retrieves door/device state from the UniFi Access system. No side effects or data modification are implied. Confidence is slightly reduced due to empty description, but the naming pattern is unambiguous. From the tool's own definition: "Tool name 'unifi_list_devices' indicates a listing/querying operation; description is empty but naming convention and server context (UniFi Access management) suggests retrieval of device information without modification." ## Use case AI agents call unifi_list_devices to retrieve information from UniFi Access MCP 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 UniFi Access MCP: ```json { "version": "1", "default": "deny", "tools": { "unifi_list_devices": {} } } ``` ## 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 - `protect_trigger_chime` — Execute — https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/protect-trigger-chime.md - …and 241 more: https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp.md ## For agents This record is a snapshot.
