Updown.io

@updown list all your monitoring nodes so I can see which regions are checking our site

Updown.io currently operates 18 monitoring nodes across North America, Europe, and Asia-Pacific. Example nodes include us-east (Virginia), eu-west (Ireland), ap-southeast (Singapore), and sa-east (São Paulo). Each node runs health checks from its region every 30-60 seconds depending on your plan. This illustrative list shows the geographic spread available for multi-region uptime verification.

This example demonstrates read-only node discovery. Useful when planning geographic coverage for uptime checks or diagnosing regional outages. Requires valid API key. The actual node list changes as Updown.io expands infrastructure, so treat results as a point-in-time snapshot.

@updown give me all IPv4 addresses your nodes use — I need to allowlist them in our firewall

Here are the current IPv4 addresses for all Updown.io monitoring nodes: 198.51.100.10, 203.0.113.42, 192.0.2.88, and 15 others across their global infrastructure. These IPs originate health check requests to your endpoints. This illustrative set represents the addresses you'd add to firewall rules or security groups to permit inbound monitoring traffic without blocking legitimate checks.

Critical for network security configuration. Updown.io can add or rotate node IPs as they scale infrastructure, so re-fetch this list quarterly or when checks start failing. This example shows IPv4 only; use the IPv6 tool separately if your stack requires dual-stack allowlisting.

@updown compare your node locations to our CDN edge cities and tell me if we have monitoring coverage gaps

Cross-referencing Updown.io's 18 monitoring nodes against your CDN's 47 edge locations reveals coverage in 12 shared metros (New York, London, Tokyo, etc.). However, 6 of your CDN edges—including Mumbai, Johannesburg, and São Paulo—lack nearby Updown.io nodes, meaning checks from those regions route through distant nodes and may not reflect true local user experience. Consider this when interpreting latency metrics for underrepresented geos.

This synthesis example pairs the MCP's node data with reasoning about your infrastructure. Highlights a real trade-off: third-party monitoring networks rarely match CDN footprints 1:1. Useful for capacity planning but requires you to provide CDN edge data in the same Space for comparison.

When you need to allowlist monitoring IPs across environments

A 5-person DevOps team runs updown.io checks against staging and production APIs behind corporate firewalls. Every few months, updown.io rotates or adds monitoring nodes, breaking checks until someone manually updates the allowlist. This MCP is the right call if you're scripting those updates or building a Slack workflow that pulls current IPs on demand. The List Node IPs and IPv4/IPv6 tools give you the exact addresses to paste into AWS security groups or Cloudflare rules. The trade-off: if you only update firewall rules once a year, the MCP is overkill—just bookmark the updown.io dashboard. But if you're automating deployments or onboarding new environments weekly, pulling IPs via Switchy beats context-switching to the vendor UI every time.

When uptime alerts need quick node-level triage

A 3-person SRE rotation gets paged at 2am because updown.io reports a service down. Before escalating, they need to know if it's a real outage or a single monitoring node hitting a transient network issue. This MCP works if your runbook includes checking which nodes are active and whether the failing node's IP is still in rotation. The List Monitoring Nodes tool surfaces the current node set in seconds, so the on-call engineer can cross-reference against the alert without opening a browser. The boundary: if your updown.io plan only uses 2-3 nodes and you rarely see partial outages, this scenario doesn't justify the integration. But for teams running checks from 10+ global nodes, the MCP turns a 5-minute dashboard hunt into a 30-second Switchy query during the critical first minutes of an incident.

When audit trails require current monitoring infrastructure lists

A 6-person security team at a healthcare SaaS needs to document all external IPs that touch production systems for SOC 2 and HIPAA audits. Updown.io is one of a dozen third-party services, and the compliance lead updates a master spreadsheet quarterly. This MCP is a fit if you're building a Switchy workflow that pulls current node IPs alongside other vendor data, so the spreadsheet stays accurate without manual lookups. The List IPv6 nodes and IPv4 tools give you machine-readable output that feeds directly into your compliance repo. The limit: if your audit cycle is annual and you only have updown.io plus one or two other monitoring tools, the overhead of setting up the MCP outweighs the time saved. But for teams juggling 5+ external services with quarterly reporting, centralizing IP enumeration in Switchy cuts compliance prep from a half-day to an hour.
