Robtex MCP server
46 tools · Last check that passed 27 Oct 2026, 01:50 UTC
Robtex's own remote MCP server gives an agent DNS, IP, AS and domain reputation lookups, and Bitcoin and Lightning Network lookups, with no sign-in. Once a day, Stackduke connects to it the way any MCP client would, with no account and no sign-in, and lists its tools. It never runs them.

The tools the server listed at the last check that passed, at its default address and settings, with no sign-in; an account that signs in, or other settings, may see other tools. What a tool is counted as doing is Stackduke's cautious reading of the server's labels, the tool's name and its description: where they disagree it takes whichever says the tool can do most, so it overcounts on purpose. It does not say the server is safe, and it does not list what a tool cannot do. Descriptions are not shown, because they are written for models and may try to steer them.

One email when Robtex's official MCP server adds, removes or changes tools, with what changed. Nothing else.
What to watch for
- Its check_email tool connects to an address's mail server over SMTP to test whether the address is accepted. Robtex's MCP server page
- DNS records and domain data come back to the agent, and text an agent reads can carry instructions for it. OWASP, prompt injection
How to limit it
With Robtex's own settings, as its documentation describes them. Stackduke has not tested them.
- Keep the agent from querying in bulk. Robtex says it may block addresses that abuse the service with excessive automated queries. Robtex's terms of service
What Stackduke is designed to do
Stackduke is designed to sit between your agents and their MCP servers: to check each tool call against your rules before it runs, hold the risky ones for a person to approve, and keep a record of what was decided.
It does not yet forward or block tool calls for customers. Today it reads what this server offers and publishes what changes.
