Koskamo

willmehr MCP

An open-source Model Context Protocol server that allows AI agents to search second-hand classified listings on willhaben.at and kleinanzeigen.de. It supports two modes: full mode using a user's own session cookie for account-specific tools, and public mode for anonymous, self-hosted HTTP access with rate limiting. The server is built by reverse-engineering the willhaben web app's JSON API.
