Nslookup vs MCP Victoriametrics

A side-by-side look at the Nslookup and MCP Victoriametrics MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Nslookup logoNslookupMonitoring · Local subprocess (stdio)DNS lookups, SSL certificates, security scanning, and propagation checks via nslookup.io60GoodAuth: not declaredMCP Victoriametrics logoMCP VictoriametricsMonitoring · Remote HTTP/SSEProvides comprehensive integration with your VictoriaMetrics instance APIs and documentation for monitoring, observability, and debugging tasks related to your VictoriaMetrics instances67GreatAuth: api key required

Verdict: choose Nslookup for monitoring work as a local process; choose MCP Victoriametrics for monitoring over a hosted endpoint. You can also run both side by side in one mcpServers block.

Tools & capabilities

Nslookup tools 23

  • dns_lookupLook up all common DNS records (A, AAAA, NS, MX, TXT, CNAME, SOA) for a domain. Returns results from a specified DNS server.
  • dns_recordLook up a specific DNS record type for a domain. Supports 53 record types including A, AAAA, MX, TXT, CNAME, SOA, PTR, CAA, SRV, DNSKEY, DS, TLSA, HTTPS, SPF, and more.
  • dns_propagationCheck DNS propagation for a domain across 18+ global DNS servers (Cloudflare, Google, Quad9, OpenDNS, regional servers, and authoritative nameservers). Shows if DNS changes have propagated worldwide.
  • webserversGet the IP addresses (both IPv4 and IPv6) for a domain by looking up A and AAAA records. Also returns the punycode and unicode domain representations.
  • ssl_certificateCheck the SSL/TLS certificate for a domain. Returns issuer, expiry date, days until expiry, certificate chain validity, cipher strength, SAN domains, fingerprint, and TLS protocol version.
  • bimi_vmcCheck BIMI (Brand Indicators for Message Identification) and VMC (Verified Mark Certificate) for a domain. Returns BIMI DNS record status, VMC certificate details, logo URL, trademark info, and expiry.
  • security_scanRun a security scan on a domain to detect DNS misconfigurations, missing SPF/DKIM/DMARC records, cookie security issues, and other web security vulnerabilities. Returns findings with severity levels (critical, high, medium, low, info).
  • uptime_checkPerform a one-time HTTP uptime check on a URL from a single location. Returns whether the site is up or down, HTTP status code, and response time in milliseconds. For multi-location checks, use uptime_check_multi instead.
  • uptime_check_multiCheck if a website is up or down from 7 global locations simultaneously: Amsterdam, Sydney, London, Frankfurt, Delhi, Warsaw, and South Carolina. Returns status, response time, and HTTP status code for each location.
  • dns_healthRun a comprehensive DNS health audit on a domain — 39 checks across 7 categories: DNSSEC (chain of trust, algorithms, validation), MX & email (PTR, MTA-STS, redundancy), DNS hygiene (SPF conflicts, wildcards, apex CNAME), TTL & SOA configuration, nameserver setup (diversity, lame delegation, EDNS0), CAA certificates, and operational maturity (security.txt, abuse mailbox). Returns an overall severity-weighted score (0–100) plus per-category scores.
  • geo_checkerCheck a domain's GEO (Generative Engine Optimization) score — how well the site is optimized for AI search engines like ChatGPT, Gemini, Claude, and Perplexity. Returns three scores (Technical Readiness, Entity Readiness, Answer Readiness), AI crawler access status, structured data analysis, and prioritized recommendations.
  • rdap_lookupLook up registration data (RDAP — the successor to WHOIS) for an IP address, AS number, or domain name. The query type is detected automatically. Returns the owning organization, network range/CIDR, RIR (ARIN, RIPE, APNIC, LACNIC, AFRINIC), country, status, registration/last-changed dates, nameservers, and abuse/registrant contacts, plus the raw RDAP JSON.

MCP Victoriametrics tools 17

  • active_queriesActive queries. This tool can determine currently active queries in the VictoriaMetrics instance. This information is obtained from the "/api/v1/status/active_queries" HTTP endpoint of VictoriaMetrics API.
  • alertsList of firing and pending alerts of the VictoriaMetrics instance. This tool uses `/api/v1/alerts` endpoint of vmalert API, proxied by VictoriaMetrics API.
  • documentationSearch documentation resources for the given search query, returning the URIs of the resources that match the search criteria sorted by relevance. This tool can help to get context for any VictoriaMetrics related question.
  • explain_queryExplain how MetricsQL query works
  • label_valuesList of label values from VictoriaMetrics instance for a provided label name. This tool uses `/api/v1/label/{labelName}/values` endpoint of VictoriaMetrics API.
  • labelsList of label names of the VictoriaMetrics instance. This tools uses `/api/v1/labels` endpoint of VictoriaMetrics API.
  • metric_statisticsStatistics of metrics usage in queries of the VictoriaMetrics instance. This tool helps to identify unused (never queried) or rarely used metrics or conversely actively queried metrics. This tool uses `/api/v1/status/metric_names_stats` endpoint of VictoriaMetrics API.
  • metricsList of available metrics of the VictoriaMetrics instance. This tool uses `/api/v1/label/__name__/values` endpoint of VictoriaMetrics API.
  • metrics_metadataReturns stored metrics details (metadata) such as name, type, help (description), and unit, and can be used to generate natural language queries. This tool uses `/api/v1/metadata` endpoint of VictoriaMetrics API.
  • prettify_queryPrettify (format) MetricsQL query. This tool uses `/prettify-query` endpoint of VictoriaMetrics API.
  • queryInstant query executes PromQL or MetricsQL query expression at the given time. The result of Instant query is a list of time series matching the filter in query expression. Each returned series contains exactly one (timestamp, value) entry, where timestamp equals to the time query arg, while the value contains query result at the requested time. This tool uses `/api/v1/query` endpoint of VictoriaMetrics API.
  • query_rangeRange query executes the query expression at the given [start…end] time range with the given step. The result of Range query is a list of time series matching the filter in query expression. Each returned series contains (timestamp, value) results for the query executed at start, start+step, start+2*step, …, start+N*step timestamps. In other words, Range query is an Instant query executed independently at start, start+step, …, start+N*step timestamps with the only difference that an instant query does not return ephemeral samples (see below). Instead, if the database does not contain any samples for the requested time and step, it simply returns an empty result. This tool uses `/api/v1/query_range` endpoint of VictoriaMetrics API.

Frequently asked questions

Nslookup is categorized under Monitoring and uses a local stdio subprocess. MCP Victoriametrics belongs to Monitoring and uses a remote HTTP/SSE transport. Pick Nslookup for monitoring work and MCP Victoriametrics for monitoring.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Nslookup has no declared pricing — check the project's own site. MCP Victoriametrics is listed as free. Auth: api key required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add nslookup and victoriametrics-community-mcp-victoriametrics as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Nslookup has a quality signal of 60/100 (Good) with 1 views, 0 installs and 23 GitHub stars. MCP Victoriametrics has 67/100 (Great) with 4 views, 0 installs and 239 GitHub stars.
