Dechonet MCP server

DechoNet MCP Server

Domain security reconnaissance for AI agents via the Model Context Protocol.

19 tools, free, no API key. DNS, SSL/TLS, HTTP security headers, email authentication, port scan, DNS propagation, reverse DNS, ASN/BGP, RDAP/WHOIS, subdomain discovery (CT logs), lookalike/typosquat detection, OWASP-mapped observable checks, brand-impersonation exposure, go-live readiness, and domain change history — what changed since the last check.

Every result comes back interpreted, not just as raw JSON: a status, the key numbers, each issue with severity and confidence, and the concrete action to take. That is what an agent needs to tell a human what to do next.

Part of DechoNet. Every tool here is also a free web tool at dechonet.com — no sign-up — backed by error-fix guides. This package brings the same checks to AI agents.

Zero-install: remote endpoint

No npx, no install, no key. Point any MCP client that speaks Streamable HTTP at:

https://dechonet.com/mcp

Claude Desktop / Claude Code (claude mcp add --transport http dechonet https://dechonet.com/mcp), Cursor, and other HTTP-capable clients connect directly. The remote endpoint also serves 3 curated prompts (auditdomain, monitorsetup, investigate_changes) and 2 reference resources.

Quick Start (stdio, Claude Desktop)

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "dechonet": {
      "command": "npx",
      "args": ["-y", "dechonet-mcp"]
    }
  }
}

Config file location:

• macOS: ~/Library/Application Support/Claude/claudedesktopconfig.json
• Windows: %APPDATA%\Claude\claudedesktopconfig.json

Restart Claude Desktop. You'll see the DechoNet tools icon in the input area.

Install

# Via npx (no install needed)
npx dechonet-mcp

# Or install globally
npm install -g dechonet-mcp

Available Tools

Every tool response ends with a link to the full interactive report on dechonet.com for the human behind the agent.
