Koskamo

theHarvester MCP

An MCP server that wraps theHarvester to enable AI agents to perform OSINT email and subdomain discovery. It supports harvesting public emails, subdomains, hostnames, IPs, and LinkedIn profiles for a specified domain using free sources like crtsh, hackertarget, and DuckDuckGo. The server runs via multi-arch Docker with stdio transport, allowing agents to ask for public contacts and receive structured JSON results asynchronously.
