Frequently asked questions

1

What is IR Toolshed MCP Server?

It is an MCP server that exposes networking and security tools (ASN, DNS, WHOIS, geolocation) as callable resources for AI agents, designed for security professionals.

2

What are the prerequisites to run it?

Python 3.8 or newer (3.13+ recommended) and the `uv` package manager. The geolocation tool additionally requires a free MaxMind license key.

3

How do I obtain a MaxMind license key?

Visit https://dev.maxmind.com/geoip/geolite2-free-geolocation-data to get a free key. Set it as the `MAXMIND_LICENSE_KEY` environment variable or provide it each time you use the geolocation tool.

4

What happens when a lookup fails?

Each tool returns a structured error response with a status of "error", a detailed error message, and the original query value, enabling graceful handling by AI agents.

5

Does the server require an internet connection?

Yes, ASN, DNS, and WHOIS lookups require network access to external services. The geolocation tool uses a local MaxMind database but still needs an internet connection to download the database initially.
