NetworksDB MCP Server

NetworksDB MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Fast MCP integration for NetworksDB API - Query IP addresses, organizations, ASNs, and DNS records using natural language through Model Context Protocol.

What you get

NetworksDB-MCP is a powerful integration that brings the capabilities of Model Context Protocol (MCP) Server to NetworksDB, enabling natural language queries for network intelligence, IP geolocation, organization details, and DNS information.

What the assistant can call

Once NetworksDB is connected, these are the calls the assistant has available:

• key_info — Get API key info and usage stats
• ip_info — Get IP address details
• ip_geo — Get IP geolocation
• org_search — Search organizations
• org_info — Get org details
• org_networks — List networks owned by org
• asn_info — Get ASN information
• asn_networks — List networks for ASN
• dns — Get DNS records
• reverse_dns — Get reverse DNS for IP
• mass_reverse_dns — Bulk reverse DNS lookup

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Configuration and credentials

You will need one environment variable: NETWORKSDB_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. NetworksDB's toolset — key_info, ip_info, ip_geo and 8 more — is a fair guide to whether it matches your workflow. It is maintained by MorDavid; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• With 11 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch NetworksDB.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the networksdb mcp server does with a few real requests.
