@codetidy/mcp-live

MCP server for live network developer tools — DNS lookup, WHOIS, SSL checker, HTTP headers, IP geolocation, and more. Makes outbound network requests via free public APIs.

Separate from @codetidy/mcp (62 pure-function offline tools). This package provides 12 tools that require network access.

Quick Start

Remote (recommended)

No install needed. Add to your MCP client config:

{
  "mcpServers": {
    "codetidy-live": {
      "url": "https://mcp-live.codetidy.dev/mcp"
    }
  }
}

Local (stdio)

npx @codetidy/mcp-live

Or in your MCP client config:

{
  "mcpServers": {
    "codetidy-live": {
      "command": "npx",
      "args": ["-y", "@codetidy/mcp-live"]
    }
  }
}

Tools (12)

DNS Tools (5)

| Tool | MCP Name | Description | |------|----------|-------------| | DNS Lookup | codetidy_dns_lookup | Query DNS records (A, AAAA, CNAME, TXT, NS, SOA, MX, CAA) | | Reverse DNS | codetidy_reverse_dns | Find hostname for an IP address via PTR record | | MX Lookup | codetidy_mx_lookup | Look up mail exchange records for a domain | | DNS Propagation | codetidy_dns_propagation | Check DNS propagation across global resolvers | | Email Auth Checker | codetidy_email_auth_checker | Validate SPF, DKIM, and DMARC records |

Network Tools (4)

| Tool | MCP Name | Description | |------|----------|-------------| | IP Lookup | codetidy_ip_lookup | IP address geolocation and network info | | Website Status | codetidy_is_it_down | Check if a website is up or down | | HTTP Headers | codetidy_http_headers | Inspect HTTP response headers for any URL | | Redirect Trace | codetidy_redirect_checker | Trace full HTTP redirect chain |

Security Tools (3)

| Tool | MCP Name | Description | |------|----------|-------------| | WHOIS Lookup | codetidy_whois_lookup | Domain registration info via RDAP | | SSL Checker | codetidy_ssl_checker | Check SSL/TLS certificate and HSTS | | Security Headers | codetidy_security_headers | Audit security headers with grading |

Architecture

All tools are read-only and make outbound network requests to free, no-auth-required APIs:

| API | Purpose | |-----|---------| | DNS-over-HTTPS (RFC 8484) | DNS, MX, reverse DNS, propagation | | IANA RDAP registries | WHOIS data (JSON-based) | | Edge runtime metadata | IP geolocation | | Target URL fetch | Headers, SSL, status, redirects |

Tool annotations:

• openWorldHint: true — makes network requests
• readOnlyHint: true — never modifies external state
• destructiveHint: false — safe to run
• idempotentHint: false — network results can vary

Why a Separate Package?

1. MCP tool count limits — Cursor caps at 40 tools; our main package has 62. Combining would exceed safe limits.
2. Different security contract — @codetidy/mcp declares openWorldHint: false (no network access). Mixing destroys trust.
3. MCP best practices — focused, scoped servers with one clear purpose.
4. Different failure modes — network tools can timeout and return variable results.
