Stdio bridge to the hosted Merlonix monitoring MCP server — domain health, SSL/DNS, MCP health checks, agent readiness, vendor status. 8 public tools, no auth.

merlonix-mcp

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

8 public tools, no signup, no API key. An optional API key unlocksauthenticated 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 onlylaunch local stdio servers. It forwards initialize / tools/list /tools/call 1:1 to the hosted endpoint and adds nothing else.
