- 01Checking DNS records for a domain
- 02Retrieving WHOIS information
- 03Inspecting SSL data
- 04Looking up geo-IP data
MCP support
It runs as a stdio MCP server and exposes cached DNS, WHOIS, SSL, and geo-IP data to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y @weiseer/dns-cache-mcpDNS_CACHE_URLOverride remote snapshot URLDNS_CACHE_LOCAL_ONLYSkip remote fetchLocal servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
