Aruba Central MCP

Report server version and Aruba Central backend authentication. Call this at session start (or after a tool-call timeout) to confirm the MCP is up, see which version is running, and verify the Aruba Central backend can be authenticated. Lightweight: it builds the client and obtains an OAuth2 access token (GreenLake SSO, reusing the cached token) — it does NOT fetch APs, switches, clients, or any other data endpoint. Always returns the same keys: ``status`` (healthy / degraded / error), ``service``, ``version``, ``base_url`` (the configured ARUBA_CENTRAL_BASE_URL, empty string if unset), and ``auth`` (ok / error / missing-env). On a degraded or error result, ``detail`` carries the reason.

List access points with device-level overview. Use this for AP inventory and availability checks. For RF details (channel, utilization, noise floor), use list_radios instead. Args: site: Filter by site name (exact match, server-side). Empty for all. status: Filter by status (e.g. "ONLINE", "OFFLINE"). Empty for all.

List all switches from Aruba Central. Returns switch name, status, model, type, IP, firmware, and MAC address.

List connected wireless clients with connection details. Returns client name, MAC, IP, SSID, band, SNR, connected AP, and auth type. For a single client's full details, use find_client_by_mac instead. Args: ssid: Filter by SSID name (exact match, server-side). Empty for all. band: Filter by wireless band (exact match, server-side). Empty for all.

Look up a single client by MAC address (wireless or wired). Returns detailed info including OS, manufacturer, VLAN, and connection status. Uses direct API lookup (no full-list scan). Args: mac_address: Client MAC address (e.g. "aa:bb:cc:dd:ee:ff").

Get detailed status of a specific access point by name. Args: ap_name: AP device name (case-insensitive).

Get a summary of all sites with AP and client counts. Aggregates data across all APs and clients, grouped by site name. Shows total APs, online/offline counts, and client count per site.

List AP radios with RF details. Use this for RF troubleshooting: channel assignment, channel utilization, noise floor, and TX power. Each AP typically has 2-3 radios (one per band). Args: site: Filter by site name (exact match, server-side). Empty for all. band: Filter by band (e.g. "2.4 GHz", "5 GHz"). Empty for all.

List all BSSIDs (per-radio, per-SSID broadcast identifiers). Useful for identifying which radio on which AP is broadcasting a specific SSID. Each AP radio broadcasts one BSSID per WLAN. Args: site: Filter by site name (exact match, server-side). Empty for all.

List configured WLANs (SSIDs) with security and VLAN settings. Shows each WLAN's name, band, operational status, security level, and VLAN assignment. Args: site_id: Filter by site ID. Empty for all. serial_number: Filter by AP serial number. Empty for all.

List all AP swarms (clusters) from Aruba Central. Returns cluster name, conductor AP, site, IP, and firmware version. Args: site: Filter by site name (exact match, server-side). Empty for all.

Get top access points ranked by bandwidth usage over a time range. Returns a ranked list of APs sorted by descending bandwidth consumption. Args: usage_type: "wireless" (Wi-Fi traffic), "wired" (uplink traffic), or "total" (wireless + wired combined). Default: "total". site_id: Filter by site ID. Empty for all sites. limit: Maximum number of APs to return (1-25, default 10). start_at: Start time in RFC 3339 format (e.g. "2025-01-01T00:00:00Z"). Max 30 days range. Defaults to 24 hours ago if omitted. end_at: End time in RFC 3339 format. Defaults to current time if omitted.

Get throughput trend for a specific AP as a time-series table. Returns timestamped TX/RX throughput in bps. Defaults to last 3 hours. Args: serial_number: AP serial number (use list_aps or get_ap_status to find it). interface_type: "WIRELESS" (Wi-Fi), "WIRED" (Ethernet uplink), or "LTE". start_at: Start time in RFC 3339 format. Defaults to 3 hours ago. end_at: End time in RFC 3339 format. Defaults to current time.

Get client count trend over time, grouped by a chosen dimension. Useful for capacity planning and usage pattern analysis. Args: site_id: Filter by site ID. Empty for all. site_name: Filter by site name. Empty for all. start_at: Start time in RFC 3339 format (max 1 month range). Must not be in the future. end_at: End time in RFC 3339 format. Must not be in the future. group_by: Dimension to group by. Supported values: - Any client_type: TYPE, ROLE, VLAN - WIRELESS only: WLAN, RADIO, SECURITY, PROTOCOL Default is TYPE. client_type: Client category: ALL, WIRELESS, or WIRED. Default is ALL. Must be WIRELESS when group_by is WLAN, RADIO, SECURITY, or PROTOCOL (the API returns 400 otherwise).

Get top clients ranked by bandwidth usage. Args: site_id: Filter by site ID. Empty for all. site_name: Filter by site name. Empty for all. start_at: Start time in RFC 3339 format (max 1 month range). end_at: End time in RFC 3339 format. limit: Maximum number of clients to return (1-100, default 5).

Get roaming history for a wireless client as a time-series table. Shows which APs the client connected to, when, and on which SSID. Useful for troubleshooting connectivity issues or tracking movement. Defaults to last 3 hours. Args: mac_address: Client MAC address (e.g. "aa:bb:cc:dd:ee:ff"). start_at: Start time in RFC 3339 format. Defaults to 3 hours ago. end_at: End time in RFC 3339 format. Defaults to current time.

Run a morning AP health check across all sites. Fetches all access points and aggregates their online/offline status by site. Sites whose offline AP ratio is *strictly greater than* ``offline_threshold`` percent are flagged as WARNING (uses ``>``, so a site with exactly ``offline_threshold`` % offline is still OK). Args: offline_threshold: Percentage of offline APs that triggers a WARNING (default 10.0). Sites at or below this threshold appear in the OK section. Pass 0.0 to flag any site with at least one offline AP. Output tiers: - CRITICAL — API connection failure - WARNING — offline AP ratio strictly above threshold - OK — offline ratio at or below threshold Returns a Markdown summary with site-level AP counts and anomaly details.
