This n8n workflow transforms the CIRCL Hashlookup API into a robust API gateway, enabling AI agents to perform various hash lookup operations seamlessly. It acts as a middleware server that exposes multiple endpoints for querying file hashes, such as MD5, SHA1, and SHA256, retrieving parent or child hash relationships, and managing search sessions. The workflow uses an MCP trigger node to receive requests via webhooks, followed by HTTP request nodes to communicate with the Hashlookup API. It is ideal for automating hash investigations, malware analysis, or digital forensics by providing an easily accessible API interface for complex hash queries within automated workflows or AI-powered applications.
