Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-network-tools Check the DNS records for github.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-network-tools
Network diagnostics tools for AI agents, exposed via the Model Context Protocol (MCP).
Tools
Tool | Description |
| Resolve domains to DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA). Reverse DNS. Propagation check across public DNS servers. |
| Geolocation and network info for an IP address — country, city, ISP, ASN, coordinates. IPv4 and IPv6. |
| Inspect SSL/TLS certificates — validity, issuer, expiry, SANs, certificate chain, cipher, protocol. |
| WHOIS data for a domain — registrar, creation/expiry dates, nameservers, status. |
| Measure HTTP response time over N requests. Returns avg, min, max, p95 latency and success rate. |

5 toolsdns_lookupA
Resolve a domain name to DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA). Supports reverse DNS and propagation checking.
Inputs: domain (required), mode, record_types.
http_pingA
Measure HTTP response time to a URL over multiple requests. Returns per-request latency and statistics: average, min, max, p95, and success rate.
Inputs: url (required), count, timeout_ms.
ip_infoA
Get geolocation and network information for an IP address: country, city, ISP, ASN, coordinates. Supports IPv4 and IPv6.
Inputs: ip (required).
ssl_checkA
Check the SSL/TLS certificate of a host: validity, issuer, expiry date, days until expiry, subject alternative names, certificate chain, cipher, and protocol.
Inputs: host (required), port.
whois_lookupA
Look up WHOIS information for a domain: registrar, creation date, expiry date, nameservers, and domain status.
Inputs: domain (required).

TDQS
A4.1/5.0
Scored across 5 tools
Disambiguation5/5
Each tool targets a distinct network diagnostic function: DNS resolution, IP geolocation, SSL certificate inspection, WHOIS registration data, and HTTP latency testing. There is no functional overlap between them.
Naming Consistency4/5
Most tools follow a clear noun_action pattern (dns_lookup, ssl_check, http_ping, whois_lookup), but ip_info breaks the pattern by using a noun suffix instead of an action. Still, all names are lowercase snake_case and clearly readable.
Tool Count5/5
Five tools is a well-scoped set for a network diagnostics server. Each tool serves a distinct purpose and the count is within the ideal range, neither overwhelming nor thin.
Completeness4/5
The set covers the most common network checks (DNS, IP, SSL, WHOIS, HTTP). Minor gaps exist such as traceroute or port scanning, but for a focused diagnostic tool these are optional additions, not critical missing functionality.
