IPRegistry

@IPRegistry look up the IP address 8.8.8.8 and tell me what organization owns it and where it's located

The IP address 8.8.8.8 is owned by Google LLC (AS15169) and is located in Mountain View, California, United States. The lookup shows this is a public DNS resolver with no threat indicators. Additional context includes timezone America/Los_Angeles, currency USD, and carrier classification as hosting/datacenter infrastructure. This is a single-address lookup returning geolocation, network ownership, and threat intelligence in one call.

This example shows the core IP lookup capability. The MCP returns rich context beyond just location—ASN ownership, threat scoring, carrier type. Requires a valid API key with IP lookup quota. Rate limits depend on your IPRegistry plan tier; batch lookups (up to 1024 IPs) are more efficient for bulk analysis.

@IPRegistry I have a list of 50 IP addresses from recent login attempts—can you batch look them up and flag any with threat indicators above 0.7?

Batch lookup completed for 50 IP addresses. Found 3 addresses with threat scores above 0.7: 185.220.101.34 (score 0.89, known Tor exit node), 45.142.212.61 (score 0.78, associated with proxy/VPN services), and 103.253.145.12 (score 0.72, flagged for recent abuse reports). The remaining 47 addresses show no elevated threat indicators. Invalid or private IPs in your input would return inline errors without failing the entire batch.

Demonstrates batch processing (up to 1024 IPs per call) and the AI's ability to filter results by threat score. This is a write-style operation that consumes quota proportional to input size. The MCP handles partial failures gracefully—one bad IP won't block the other 49. Useful for security audits or access-log analysis.

@IPRegistry parse these 10 User-Agent strings from our mobile app logs and summarize which devices and OS versions are most common

Parsed 10 User-Agent strings. Device breakdown: 6 iOS devices (4 iPhone 14 Pro on iOS 17.2, 2 iPad Air on iOS 16.5), 3 Android devices (2 Samsung Galaxy S23 on Android 14, 1 Google Pixel 7 on Android 13), and 1 desktop Chrome/Mac. Browser engines: 6 WebKit (Safari/iOS), 3 Blink (Chrome/Android), 1 Blink (Chrome/desktop). Most common configuration is iPhone 14 Pro running iOS 17.2 with Safari. This batch parse (up to 256 strings) lets you aggregate device telemetry without manual regex parsing.

Shows the User-Agent parsing tool paired with AI synthesis. The MCP returns structured device/browser/OS data; the AI aggregates trends. This is a read-heavy operation useful for analytics dashboards or compatibility testing. Parsing is deterministic—same string always yields same result—but relies on IPRegistry's device database being current.

When IPRegistry beats raw logs for threat response

A 6-person SaaS team sees a spike in failed login attempts from 200 IPs overnight. The on-call engineer needs to know if it's a distributed bot or a single ASN before escalating to the security vendor. IPRegistry's batch lookup returns threat scores, carrier data, and ASN relationships in one call—no need to parse raw logs or chain multiple API requests. The 1024-IP batch limit covers most incident windows without pagination. If your team runs a WAF or SIEM that already enriches IPs, this MCP is redundant. But if you're still grep-ing nginx logs and manually checking IP reputation sites, IPRegistry turns a 20-minute fire drill into a 2-minute Slack update. Worth the API key if you handle security incidents more than once a quarter.

How batch ASN lookup scales for transaction review

A 12-person marketplace team reviews 50-100 flagged transactions daily, looking for patterns across buyer IPs. The fraud analyst needs to see if multiple accounts share an ASN or hosting provider without opening 50 browser tabs. IPRegistry's batch ASN lookup returns organization and network-prefix data in one request, surfacing shared infrastructure that manual checks miss. The 16-ASN batch limit means you'll loop for larger review queues, but the inline error handling keeps bad data from blocking the rest. If your fraud tool already does IP clustering, skip this. If you're still copy-pasting IPs into WHOIS lookups, this MCP cuts review time by 70 percent. Best fit for teams that triage fraud manually before handing off to automated rules.

When to use IPRegistry for device segmentation

A 4-person product team wants to segment feature adoption by device type—mobile web versus desktop, iOS versus Android—but their analytics tool only logs raw User-Agent strings. IPRegistry's parser handles 256 strings per call and returns structured browser, OS, and device data without regex maintenance. The input-order guarantee means you can join results back to session IDs without extra bookkeeping. If you're already using a client-side analytics SDK that parses agents, this is overkill. But if you're working with server logs or webhook payloads that dump raw strings, this MCP turns a messy ETL job into a single API call. Use it when you need device breakdowns for a one-time analysis or quarterly report, not for real-time dashboards.
