Summary

This server gives your AI agent instant access to cached DNS, WHOIS, SSL certificate, and geo-IP lookups without burning tokens or hitting rate limits on live queries. It's part of the weiseer family of cached oracles, which basically pre-fetch and snapshot common lookup data so your agent doesn't have to shell out to dig or whois commands repeatedly. The pitch is simple: instead of spending 100 to 1500 times more in tokens and latency doing these lookups yourself, you pull from their snapshot. You'd reach for this when building agents that need to inspect domains, check SSL certs, or geolocate IPs as part of security audits, network diagnostics, or reconnaissance workflows.

@weiseer/dns-cache-mcp

DNS/WHOIS/SSL/geo-IP cache MCP server for AI agents. stdio MCP server.

Part of weiseer — AI-agent-native cached oracles.

Install

npm install -g @weiseer/dns-cache-mcp

Use with Claude Desktop / Cursor / Cline / Continue / Windsurf

{
  "mcpServers": {
    "dns-cache": {
      "command": "npx",
      "args": ["-y", "@weiseer/dns-cache-mcp"]
    }
  }
}

Why use this instead of your agent doing it itself

The DIY cost in token-spend, latency, and rate-limit risk is 100-1500x our cost. See the weiseer organization README for the economic argument.

Environment

  • DNS_CACHE_URL — override remote snapshot URL
  • DNS_CACHE_LOCAL_ONLY=1 — skip remote fetch
