merlonix-mcp

MCP access to Merlonix — live infrastructure monitoring tools for AI agents. Domain health (SSL + DNS + registration + reachability), MCP server health checks with an A–F security posture grade, AI agent-readiness scoring, email blacklist checks, broken-link scans, and live status for 11 major cloud vendors.

8 public tools, no signup, no API key. An optional API key unlocks authenticated account tools (managing monitored assets and alerts).

The hosted server (preferred)

Merlonix runs a remote MCP server over Streamable HTTP (protocol 2025-06-18):

https://api.merlonix.com/mcp

If your client speaks Streamable HTTP natively, point it straight at that URL — no local process needed:

# Claude Code
claude mcp add --transport http merlonix https://api.merlonix.com/mcp

// Cursor / other JSON-config clients
{
  "mcpServers": {
    "merlonix": { "url": "https://api.merlonix.com/mcp" }
  }
}

This bridge (for stdio-only clients)

This repository is a thin stdio↔Streamable-HTTP bridge for clients that only launch local stdio servers. It forwards initialize / tools/list / tools/call 1:1 to the hosted endpoint and adds nothing else.
