Overview

AI-generated overview

DNS Spy is a remote MCP server that lets an assistant check live DNS records, propagation, WHOIS/RDAP, SSL and look-alike domains for a domain.

What you can do
Look up live DNS records for a domain and check how they resolve across nameservers or locations (propagation). Retrieve domain registration details through WHOIS/RDAP. Inspect SSL certificate information for a domain. Find look-alike or similar domains for security monitoring.
When to use it
Useful when you need to verify DNS configuration, confirm that a change has propagated, check registration or certificate details, or look for typosquatting and look-alike domains during domain security reviews.
Requirements
A remote MCP endpoint at dnsspy.io over streamable HTTP. Authentication is required: either an OAuth 2.1 sign-in from the client or a DNS Spy API key sent as a Bearer token in the Authorization header. Network access to dnsspy.io is needed.
Before you install
The server requires a DNS Spy API key or OAuth sign-in; treat the Authorization credential as a secret. Queries reveal which domains you are investigating to a third-party service. Lookups are read-only, but confirm whether your plan has usage limits or costs before relying on it.

Installation

In SourceWeft

  1. Open DNS Spy in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.dnsspy%2Fdnsspy/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
