Greynoise Overview
Greynoise is an unofficial MCP integration for the GreyNoise Community API, delivered through the Pipeworx gateway. Its `ip_context` tool classifies an IP address as noise or RIOT and returns associated name and last-seen information. Use it from an MCP client through the hosted endpoint, from a local npm stdio bridge, or with direct HTTP requests. Authentication can use a Pipeworx platform key or a GreyNoise key supplied through the gateway URL.
Primary Use Cases for Greynoise:
- Classify an IP address during an agent-led investigation
- Check whether an address is associated with internet scanning
- Retrieve an IP's GreyNoise name and last-seen details
- Ask Pipeworx to route a natural-language question about GreyNoise data
