# unifi_update_device_radio A write tool on the UniFi Access MCP MCP server. Agent View of the PolicyLayer registry record for `unifi_update_device_radio`. HTML page: https://policylayer.com/tools/io-github-sirkirby-unifi-access-mcp/unifi-update-device-radio ## Facts - Tool: `unifi_update_device_radio` - 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: Write (Medium 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": "unifi_update_device_radio", "arguments": {} } } ``` ## Why unifi_update_device_radio is rated Medium The tool modifies device radio configuration, which is a reversible change to physical access control hardware. This is Write rather than Execute because it targets configuration rather than triggering actions. Severity is medium because misconfiguration could disrupt access control or communications, but the change is not destructive or financial. From the tool's own definition: "Tool name 'unifi_update_device_radio' indicates modification of device radio settings. Server context shows management of UniFi Access door systems. The 'update' verb indicates a Write operation (reversible modification)." ## Use case AI agents use unifi_update_device_radio to create or update resources in UniFi Access MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UniFi Access MCP environment. ## 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": { "unifi_update_device_radio": { "limits": [ { "counter": "unifi_update_device_radio_rate", "window": "minute", "max": 30, "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 - `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.
